[Update October 13th] Working very hard right now to organize the shipping of the Pellet Extruder and other tasks related to Greenboy3D like organizing a supply of pellets for everyone and a pellet extruder wiki, which is why I sometimes have trouble answering everyone immediately. Most parts for the extruder have already arrived and have been processed & packed for shipping, however the pellet extruder screws are still in manufacturing since this is the most complicated and costly part of the pellet extruder. I believe that the first units will be shipped out by the end of October. Due to the additional organizational tasks related to the supply of pellets, there is simply more work that needs to be done. This includes staying in contact with many companies selling different types of plastics & watching out for good offers, requesting samples, testing them, negotiating prices, organizing the transportation of tons of plastic pellets, and so on. These tasks also take up some of my time, which would otherwise have been spent on the Wiki/Knowledge Base platform and the guide videos. Just a couple days ago, for example, I ordered and paid for 8,600 kg of PLA pellets, which will likely be transported to my location from Slovenia next week. 2500 kg PETG pellets are already in my possession, but more of other types are needed like: ABS/ASA/ABS-GF/ABS-GB PET TPU/TPE (various Shore levels) PA GF/CF Additionally soon there will be a new update about the ongoing progress (including the one about pellets) 🙂 If you want to get some additional pellets along with your order then that is possible however you need to consider that, while the pellet extruder will be shipped for free there will be additional shipping costs for pellets. However I will keep you updated regarding the pellets. The only thing I am not sure about is whether I should also get these extremely elastic pellets I showed in one of my videos, after doing more research it turned out these were not Shore 5A, but Shore 30 (with out the "A") which is significantly below Shore 0A meaning even more elastic and flexible than Shore 0A The only problem is that these pellets are quite expensive compared to other plastics and could only be offered for prices like 12,99 USD/EUR per kg (way higher than the other plastic types like PLA, which will probably go for 3,5 USD/EUR) Should you have more questions or concerns please feel free to contact me anytime - I am here to help.
Hopefully you remember to show love to your early supporters 😁 I signed up for your email notifications because I think you're onto something that's going to shake up the extrusion printing industry in a big way! 👍 Question: Have you already made an efficient system for recycling/shredding filament for reusable pellets as well?
Big companies make a simple idea look complicated to ask for a lot of money while wise guys like you make it really simple and cheaper and show that can it be done without a lot of mystery. This is the easiest subscription button click I have ever done. Very nice, hope some day I can use this.
Maybe the bucket you empty unused pellets into is itself a modular piece of the hopper so you don't have to keep transferring over and over, and loading the machine becomes easier with less risk of spilling pellets everywhere
There are some major flaws in your reasoning. The first is that you think one guy doing it for fun is somehow better than multiple teams of engineers. Another flaw is that simple does not equal the best or good, maybe the other companies solutions were more complicated for good reasons. A major flaw is thinking this is cheaper, one guy doing it and posting about his progress publicly will not have to worry much about the cost of their time whereas a company needs more engineers and needs to pay them high salaries which then gets passed on to the customer, this also seems to be just a prototype, so whilst it may work it may need significant work to make it producible on any reasonable scale which again takes time and money. Also there was never any mystery about pellet extrusion if you did any research at all, injection moulding machines have extruded from pellets for decades. Likely the reason that companies haven’t focused on pellet extruders is because filament extruders are generally just better. There seems to be no benefit to direct pellet extrusion other than cost and when turning it into filament first it is easier to add colour or composites. With the method shown here it would be difficult to add anything into the plastic consistently. If you need to 3D print at large scale or want to reduce costs then you likely can afford to buy a filament extrusion machine and just buy pellets and turn them into your own filament and then use normal off the shelf printers. The cost of outfitting a large print farm with pellet extruders far outweighs the cost of just buying filament or your own filament extrusion machine.
This could legitametly be a million dollar idea, and for the value that it can and I believe will add to people's lives, I feel wholeheartedly that you should be rewarded for your phenomenal efforts. Thank you so much for taking the time to develop this product and share it with the world. I wish you nothing but 100% success, financially and beyond, with the launch of your invention!
This isn't a million dollar idea however, there were 2 pellet extruders made in 2015 at different universities in Sweden. Both were small in this regard and one of them continued making industrial machines. Very much the same design as this, however this is a bit more well designed from what I would imagine would be a passion project and a lot more time :)
Umm, nobody sees the main flaw? Colors. These small extruders can not mix properly pigments into the material. That's why industrial extruders are huge.
This will make testing 3D prints so much easier since i can do more tests and I won't feel bad about using a large amount of supports anymoe. All the waste can be just ground down and reprinted.
Yes but you need to keep in mind ground print waste is not exactly same as original, while printing some substances which help make p4inting easy vaporize, so petg when ground isn't petg anymore, it's like printing pet, more stringy less forgiving
@@howabout2138Obviously _some_ plastics are going change properties once heated and cooled and not _every_ filament type is recyclable... That doesn't change the fact that many filaments _are fully recyclable_ and with how common 3D-printers are getting, the ability to recycle even ½ of the plastics used will be *huge* in lowering the amount of plastic waste and environmental impacts of 3D-printing 💯👏
No no no no you can´t simply keep recyngling that crap over and over again, it´s not like a metal plastic degrades over time you will always have to add virgin material, probably at least 50%. But this opens up new possibilities, like color mixing, recycling, keeping material dry or drying it in real time etc.
Recyled materails test printing or print your going the sand smooth anyways sounds like a good idea for printer poop/fails seem like a interesting way to deal with it.
That is definitly the main goal with this, I only need to figure out a better, easier and cheaper, way of recycling failed prints back into pellets. What however would be revolutionary (which is also something no one even imagines about) Is that you actually could recycle you general home plastic waste like jogurt cups, bottles and so on... into usefull objects 🙂
This is by far the biggest advance i have seen in years ! And the dark truth is simple : price of the filament vs pellets … A full métal hotend with more heating power can probably print almost any material at a fraction of the cost. Keep this up !
How's it possible that big companies like Prusa and Bambu don't have anyone prioritising this sort of fix? Because they'd lose money on selling filament? Perhaps this will be yet another gift of open source. If this tech takes off on cheaper printers, they big boys will be forced to adopt this ASAP to avoid a mass exodus from their machines. Brilliant!
I'd say more or less yeah. I mean filament printers are cheaper and easier to make. But for many places, they can cut printer costs by shifting their profits to the filament. Just like how you can buy an inkjet printer for $30, but the ink costs $50 despite costing only about $0.10 to make. Filament is WAY less of a rip off than inkjet, though, so I don't mind the hit too much. But I would love to have an open source option like this in order to at least feel less wasteful, and can order materials cheaply and in bulk.
exactly. because companies thrive on "lifetime consumers" (aka. geniuses), not free thinking individuals who can see through the curtain on the stage (of life) who could potentially distrupt the game in a heartbeat if there is an unjustified markup in retail in any market to be balanced out. if a filament costs arms and legs compared to the raw material price this imbalance will sooner or later be resolved with.
Maybe it doesn't work that well, print quality is not that good, speed is super slow. You see like there was already a cheap way to color prints before the AMS: an airbrush. But it's complicated, it takes skills, most people want to hit print from the smartphone and go away.,
You could also greatly decrease weight by using flexible shaft (similar like dremel use for example) and moving motor to upper frame. It should work pretty ok, it could cause some retraction issues as it's basically just a coil most of the time but well, maybe worth to give it a try.
I think that what you doing right now is going to change the industry quite drastically. And I do love the idea you provide to us. Thank you for your hard work.
Wow Amazing work! You have solved the major headache people has by trying to find the best filament. With pellets we only need to find the best material for the application. Thanks.
Very cool update video! I'm very impressed not just by the cool tech, but by the very high standard of video production and explanations. Very inspiring!
If there wasn't an ocean seperating us, I would be actively throwing money at you. Thanks for the full assembly video, addressing some of the common failure points, and the engineering that went into using only common parts. Looking forward to putting together my own when this gets released!
Fun fact. Using the same revolutionary technology that allows for us to watch a video of him from across an ocean, average folk like us can throw money across an ocean back at him.
You can throw money from anywhere in the world. Paper money in USD is FIAT Currency. It has no really value. It's just based on whatever people are willing to submit to accept as it's value.
What a great view of your progress designing a simple and very smart pellet extruder. The coolest part is the firmware compatibility, great work. Looking forward to the next video.
The natural next video I think is see the extruder being loaded and printing with at least one material, then you can use different materials in multiple videos. Or course, it is part of my expectations to know how to access to the designs ad also to the metal parts of the extruder. Keep it going.
Your entire production here is incredibly impressive. Every question I had, you answered it just as I was asking it in my head. Video quality and background is great and you have an incredible new product along with links to an email list and everything?! And it’s only your second video? Mind blown dude!
The *entire movement* for "home-based 3D-printing" was started to make open-access small scale production & prototyping easily accessible for everyone and to allow home-based makers, engineers, & artists to be able to bring their own computer models to reality 💯 That's why I was starting to get really disheartened at seeing companies lean more into proprietary software/hardware and price-gatekeeping the best materials/newest technologies... 🤦 But seriously, you have resparked my passion/hope that 3D-printing can & will eventually reach its full potential as it was originally intended‼️😁👍
Nothing about 3D printing says it has been or is intended to be open source or open access, that is just what you want it to be. The point of home 3D printing is to allow people to 3D print at home, it doesn’t really matter if the printer is proprietary or open source. The first 3D printers weren’t open source and were never intended to be. So what if more closed source companies came about? If you don’t want to use closed source then don’t use it, it is as simple as that. However you can’t deny that closed source printers are making 3D printing much more accessible, why haven’t open source printers done that yet? How is a company like Bambu Lab able to make better printers with more features that are easier to use for a better price than any open source company? If you want open source to compete then you need to help it compete, if you want the open source equivalent to a Bambu Lab printer then the open source printing community or a company need to make one. A lot of people seem to forget that open and closed source can coexist, we don’t need to choose one or the other and neither is inherently better or more moral than the other. You need to ask yourself though, why isn’t open source at the same level as closed source printers? Some aspects I do agree with though, particularly in regards to patents. The patent system is broken and really needs fixed. We still need patents but patents for fast developing fields like 3D printing should be short, two years at the absolute maximum and you should only be able to patent implementations, not concepts.
@@conorstewart2214 Bro. Then entire home 3D printer industry started open source. Sure, 3D printing existed in industrial and high-end prototyping first. But that was inaccessible to anyone who didn't have hundreds of thousands to throw at it. The reason why so many of these companies and sub $1000 printers exist is because of open source. Just because Bambu or whatever doesn't share their design files doesn't mean they didn't lean heavily on existing open source technology to get their products out. Ever heard of Prusa? Makerbot? Ultimaker? Most of the tech that 3D printing companies that aren't open source sell (Creality, Bambu, etc) started with open source. They may not be using open source to produce their products, but they copied many of the innovations of others. Bed leveling tech (touch sensors, magnetic, etc), power failure recovery, slicer software, motion systems, etc all came from open source projects and companies. Take the humble Ender 3 for example, a $250 printer. First off, they run marlin. Open source. The entire motion system is a copy of Prusa's i3. Open source. Bed leveling sensor, a copy of the BLTouch. Open source. OK, so they designed their own control board and extruder, big deal. The entire product and the very demand for it would not exist without Josef Prusa's original i3. And that wouldn't have existed without the RepRap movement, started by Dr. Adrian Bowyer. The entire reason why this industry exists in a way that normal people can access it and use it is because a few people figured out how to do it cheaply and at home and shared that with the world. If that had not happened, I fully believe that 3D printing as a hobbyist industry would not exist. Without the maker community, only large business would be doing any type of 3D printing at a cost of tens of thousands at the very least.
@@conorstewart2214I agree on two facets 1 : open & closed source "can coexist", if you as a private entity want to make and sell something without telling people how it works that's your right. However, that doesn't mean it cant be socially or culturally discouraged, it just means you should have a legal right to do it. Calling someone random on the street a dickhead is a legal right, and it should be, but it still makes you an asshole. 2 : patents are broken. I'm dubious on the idea of patents in general, but I could be convinced they're a necessary evil to some extent. (Generally I fall more in line of the camp "if you don't want people to use products in certain ways, YOU can invest in trying to stop them, but the tax payers aren't your enforcers", so DRM, trade secrets, etc. are all fair game, but if someone leaks the code, reverse engineers it, cracks the DRM, etc. thats also fair game, thus things can reach a natural and stable equilibrium) With that said, I've seen some ludicrously simple patents that aren't even a design or design concept but just a vague idea, and they still don't expire for decades. IMO "vague idea" patents shouldn't last more than a year, "I can see the innovation there but thats pretty bloody simple" can last 2-3, "alright, yeah, thats fairly unique" ~5, and "holy shit, yeah, this is pretty huge and could be big" ~7. Businesses getting to a market first already have an insane competitive first-move advantage and can grow their market niche by making their products better, you don't need two decades of forced exclusivity too. Esp. since many new ideas are fairly logical progressions based on the cultural collective unconscious. A lot of the "unique ideas" you had were probably had by dozens or hundreds of other people because they originate from the same core ideas currently prevalent in the cultural zeitgeist. In other words, chances are without a patent someone else would make it within a few years too, but with a patent they can't without engineering around your BS. I mean christ imagine if Apple got a patent on the smart phone. No, not the iPhone, the smart phone. I've seen patents WAAAAAAY more far reaching then that, and yet if they did get that patent they would *_actually_* still have the monopoly spineless #RtR consumers claim they do, since that patent wouldn't expire until at least ~20 years after the first iPhone was released. With that said, you are completely wrong about 3D printing. 3D printing as we know it today was and frankly still is borderline extremist open source. Starting ~2005 projects like the Reprap started going with the explicit goal of open sourcing and decentralizing manufacturing. In fact, this started before the patents for FDM even expired. (2009) Prior to this the idea of individuals, let alone average consumers, owning a 3d printer was fucking laughable. We're talking hundreds of thousands of dollars here, these were exclusively industry targeted devices. 3D printing is a market niche that was conceived, incubated, birthed, developed, educated, graduated, and is now getting a full career in Open Source. Additionally proprietary offerings rarely do much all that special, with open source offerings almost always being generally better except for, again, patents. Closed source has a right to exist, but that doesn't make it good. If people are willing to buy what you are selling every party involved has a right to make that transaction, but that doesn't mean what you're selling is actually a good product or is even better than alternatives, it just means that, for one reason or another, your customer wants it and is willing to buy it. Eating 5 pounds of bacon is not a good idea, but you are just as free to sell 5 bounds of freshly cooked bacon as you are to buy and then consume 5 pounds of freshly cooked bacon. (Or buckets of cheese)
Had an similar view of this happening soon to 3d printers while I work with plastic injection and have been producing pellets for long time. I find your minimalistic screw pellet struder very intrincate and yet simple. Am looking forward on your development...this is real engineering at its finest. Open up already a Patreon or something.
Absolutely amazing!!! The way you managed to unload the pelets is mind blowing!!!! I will watch all of your videos, this is so amazing! Congratulations! This is engineering as its best!
When a smart person commits to a revolutionary project with dedication and passion this is what we get. I've been 3D printing since 2017 and honestly this is the first time ever considering a pellet extruder! Removing the obstacles and optimizing the system while keeping the advantages of the pellet extruder and an accessible price is one heck of an achievement. Wish you all the success!!!
I'll do my best to release it as fast as I can, but I want to perfection it by it becomes available. (German Engineering Habit)) 😅 What would you like to see next? 🙂
This looks like itll be game changing for print farms and prototyping. I dont think itll be as useful for personal use, but it wont be detrimental thats for sure. Youve really done alot to make it so simple and user friendly, cant wait to see it completed and hopefully ready to purchase as a kit or something.
Very impressive! Great engineering here. I haven't done much 3-d printing in the past several years due to work and other hobbies, but this has motivated me to get back into it!
@@greenboy3d Perhaps an assembly and first print video? Would be useful for anyone who plans to purchase as well. A demo of using a high end filament like carbon fiber on a fairly large print and comparing the price would be cool.
I used to work in the molding industry for nearly a decade and gave you a more detailed answer than you probably asked for. interested in your work, product, and where this thing goes!
This is a nice extruder, looking forward to seeing the end-product, maybe even one in my hand. But the price of pellets varies a lot. Yes, if you go for the plain plastic pellet types that are used in the plastic molding industry you can get very cheap stuff. But most of the well known filament brands have additives to make the plastics more 3D printing friendly and while they do sell the pellets too, you pay premium prices for this (about 50% of the filament price when I looked around). So pellet extruders make the most sense on larger printers that are used for high volume production jobs. I still think that using a pellet extruder on a consumer or prosumer style printer is a nice thing to have.
True about the material - but the real kicker here is recycling. If you only use Prusament, you could shred your misprints, feed them into your pellet printer and use the stuff instead of throwing it away. I thing that scenario is much more interesting than the pellet printing as such.
@@greenboy3d I want to see more videos of it in action please. I wonder if it can be made smaller? I wonder if we can push manufacturers to make the PLA beads even smaller. let's start a revolution. On the premise that this idea will save energy costs for everyone.
I want to know if I can get the STL file for that drive screw. Grouches on reddit seem to think that drive screw will be impossible to mass produce for a reasonable price, I think that it wouldn't be that complicated. @@greenboy3d
Thank you for publishing the details of your design. This should help protect you from any patent related issues, since you have put the design in the public domain. I do hope this design is more widely adopted, and even if I would buy pellets for most of my "cheaper" prints, I'd still buy filament for some things.
Retraction is why it's not mainstream I almost guarantee, or the lack thereof. The only way I could figure to do it would involve precise tuning to essentially "coast" to the "retraction" point and you just run out of material in the perfect amount instead of sucking it back in a little. The retraction of molten material without a fixed point to pull back from is the issue of course, maybe an air compressor but to create a vacuum instead of pressure? Idk man, this is awesome with a lot of potential!
Retraction in a filament extruder is not caused by the filament retraction itself, but by the underpresure it create. And our atmospheric air pressure then presses against the remaining molten plastic through nozzle hole preventing it for a short time to ooze out until the presure levels balance themselfs What would you like to see next? 🙂
With Pressure Advance the need for retraction is significantly lower, and with some plastics, retraction almost barely works anyway, PETG for example. Pressure Advance should work the same way with this pellet extruder as it does with a filament extruder. I run 1mm retraction on my direct drive converted Ender 5 Plus, and pressure advance (running Klipper) and it works pretty well with PETG, very well with PLA. I dont print esthetic parts though, only functional stuff where I prioritize strength over looks so run low cooling and high extrusion rates with high temps, neither of which helps with looks :D
Assuming we have a suitable shredder for unwanted prints that could be used with this system, I'd say this is a massive win for the environment! Amazing work! I am looking forward to seeing how this develops further.
Very clever engineering, well done! Does this work with the new generation of high speed FDM printers. I would imagine the extra mass on the print head would be a major issue when these printers run at such high start and stop accelerations as well as keeping the pellets feeding at these high accelerations. Also will the resonance compensation algorithms still be able to account for the mass of the print head/feeder.
I can see why for hobbyist-level machines, manufacturers have little incentive to push for pellet printing - especially since they also usually sell filament spools themselves. But for large print farms that go through hundreds or thousands of kg per month, it would be a big boon, and some of them even develop their own printers. How come they didn't develop this tech yet? Would be very curious to hear your take on that. Thanks!
I think the main reason stopping most people is the inherit flow consistency issues that come with pellet exteiders. Pellets aren't the same as filament and there are always going to be some amount of gaps between pellets which causes inconsistencies in flow which are much more difficult to tune for. With most designs I've seen, it takes a good amount of experience and time to be able to produce an acceptable product with pellet extruders
@@daliasprints9798I'd say a combination of increasing pellet pathway & decreasing pellet size is the route to optimize👍 Even though it takes more processing to get smaller pellets I'd wager the its still ultimately much less processing to get 2mm pellets than it is for standard filament! Not too mention smaller pellets = faster more efficient heat transfer and melting when extruding and ultimately if you can feed/melt pellets in the screw at a rate that equals or exceeds extrusion rate, then the inconsistent extrusion due the pellet gaps will be all but eliminated 💯
I want to buy it! So much of my printing is exploratory, I am already using recycled PLA and am always looking for more cost effective solutions for my prototypes. Excited for your product launch!
TIME TO LAUNCH MY FRIEND. You should be shipping development kits already. Most people are still tinkering with filament extruders. Why grind up material and extrude it only to be fed back through another hot end, just buy/ make pellets and feed them. Ender 3s are $150 in the US right now. I want the metal parts ASAP! Also the tech you have been developing. I could buy a commercial pellet printer but that's many times the cost. I want a sub $300 (total printer cost) printer on my bench tomorrow. Your solution seems more refined than most. Release at 80-90% refinement or lose out. Perfecting your design is taking too long. I've read many of the comments and those folks don't seem to recognize how close you are to a breakthrough solution. I would love to see the PLA tech first and then the TPU after that. Please ignore the "critiques" below. I've been following 3D printing tech since 1986 when it was first invented. You have a game changer here, just get it deployed.
Depends what your plans are. If you plan to sell a assembled product, 2.5-3 times what the base cost is. However cost of scaling desighns and creating a distribution network and the cost to humanity if the design is stuck in IP prison for 30+ years would be prohibitively expensive and just be repeating the same mistake every designer of this pellet system has yet to fall into. Instead of you sell affiliate link parts kits and a tutorial on a platform with advertisements you could avoid such issues and save yourself headache of calling manufactures and distributors with extortionate cost to entry and mitigate. A lot of countries just steel patents anyway. Sling Shot Chanel has a great vid on the hassle and lawyers involved for mediocre results. Maybe though if you mass adoption and mass donation you can set up your site (agian with affiliate links) a “pay what you can system” with a recommended amount. It scales well with viral content and I’m sure the people won’t mind supporting the original Prometheus and calling out people who don’t credit if you do it like that. You can even add a few (are you sure you don’t want to donate?) links in the web page flow just to give people a reminder. It’s not scummy to ask for support if you are doing humanity a service and it’s pay what you can.
In short open source with your web page. Web page has your tutorials and affiliate links to make your parts kits. The site has advertisements on it and a “recommended donation amount”. Then add pop ups in your web page flow saying “are you sure you don’t want to donate to the inventor of this product?” “Are you really sure? Not even 3 dollars?”. But if they make it through the pop ups, it is a “pay what you can” system for the affiliate parts list including 0 as a option. Though the adverts and affiliate links should compensate you even for the people who just go to download and refuse to support regardless. This is good and you get clout for open sourcing and guarantee best prices. Maybe you could even sell merch or have a “#(your pellitPrinter name)” so others can easily post links to your page in copy cat comment sections.
I like poeple that put their effort to finding solutions. I would not buy expensive pellet extruder as I do not print much but for your extruder I would pay. Great job, keep on ! Looking forward to further progress and other inventions !
This is absolutely fantastic! The first question I have in mind is how retraction is handled by the system, and the impact it has on print quality so I subscribed to your channel and will look at your other videos. Thanks also for making the video so educative and describing the typical challenges with pellet extruders. I loved how simple is the solution to swap pellets 😃
Could this same method be used as a standalone device to make spools of filament? It seems like you’d retain basically all the benefits of using pellets, but you are still able print regular filament, and can use it for multiple printers without modifying all of them
You wouldn't need anything as complex as this to do pellet extrusion for filament. Filament extruders are FAR easier to make as you control the filament diameter by how much you pull the extruded material. Many think you extrude at the final diameter, but you actually extrude at a much larger diameter, and you pull it as it runs through the cooling bath to get down to the target diameter. Some will use gravity to control the diameter thickness, but those systems are much harder to tune to get a consistent filament diameter.
This is so, so cool I'm going to try and build one as soon as I get my printer up and running again. Being able to use pellets would be so awesome for a bunch of ideas I have You, sir, are freaking awesome
DU BIST DER HAMMER KRISTIAN!!! Ich danke dir!!! Eine geile Idee nach der anderen haust du hier raus, machst das Leben von vielen Menschen einfacher und hilfst somit der 3D-Druck-Welt sehr Weit voran zu kommen. Du solltest am Ende evtl. noch erwähnen, dass nach einem Umbau nur die E-Steps eingestellt werden müssen, da die Übersetzung anders ist als mit einem Filament. Zu deiner Einschätzung am Ende würde ich sagen - viele Drucker Hersteller produzieren ihr eigenes "teures" Filament, ich denke allein durch diese Tatsache gibt es wenige Ambitionen zu so einem Pellet-Extruder, denn dann würde diese Einnahmequelle für sie verschwinden ;-)
Das sehe ich genauso. Und die meisten Ingenieure o.ä. denken oftmals viel zu kompliziert. Da sind "Hobbybastler" meistens effizienter. Ich bin auch schon sehr gespannt wann der Extruder rauskommt und was er letztendlich kostet.
@@joherberth9230 Lol ich bin gespannt wie viele Ingenieure du kennst .... Eine Firma muss ein sicheres Produkt für Vollidiot liefern die sich nicht verletzen können oder ihren Hamster drin backen, ein Hobbybastler kann eine PLA mouting plate rausbringen obwohl man schon heute weiß, dass es Schrott ist da PLA einfach ein kack Material dafür ist, aber egal wenn man es nach 200h wieder neu druckt und dran bastelt im Hobbybereich spielt das keine Rolle. Hobbybastler nehmen einfach keine Rücksicht auf Bedienerfreundlichkeit, Sicherheit, Dauerlauf etc.
Danke für die inspirierenden Worte ❤ Du hast vollkommen Recht mit deiner Annahme mit der 3D Drucker Industrie :) Was würdest du gerne als nächstes sehen?
@@greenboy3d sehr gerne, du hast es verdient! :) vielleicht kannst du den Bereich hinter der Schnecke, wo man das Granulat sehen kann / raus holen kann, etwas runder und etwas trichterförmiger gestalten, damit die hinteren „Pellets“ besser vorne raus flutschen können, dann muss man hinten nicht so rum machen mit Werkzeugen.. ;-) ich habe dir bereits Anregungen über deine Website zu kommen lassen.. Zum Beispiel um den Antriebsmotor nach „Extern“ zu verlagern, in dem du eine Biegsame Welle / Biax dazwischen schaltest, zwecks der Kraftübertragung.. :)
As the new president of Argentina Javier Milei says, You can only be successful by manufacturing better quality goods and services at a lower price... and at the same time be a social benefactor.
I love this man. I'm brand new to 3D printing, so I can't provide sugestions, or meanifully contribute to the convesation. I just want to offer my encouragement, I think this is a really wonderful and helpful project! Please keep working on this, I will absolutely be building a printer to use with this once I have enough experience to know what I'm doing!
next thing you know you will design a pellet dryer to either integrate into the hopper or have a separate dryer hopper that feeds the main hopper. then you can also add pigment directly into the pellet mix. you know just like a pro industrial extruder
You could "reinforce" the hopper with silica gel that is going to suck up all the moisture in the Hopper keeping pellets dried :) What would you like to see next? 🙂
actually you could run heater pads on the sides of the hopper walls, do to the distance of the hose and hot air rising out of it , it should create a natural circulation of air including some vacuum from the bottom of the hose or chamber of the extruder@@greenboy3d
The Chinese are going to put up a clone for sale just based on this video alone. Hurry up with the release so that you can get a part of the customers.
I'ts amazing to see what you've achieved with this project and the potential impact of this is huge! With this mod and a belt printer like the Creality CR-30 a whole new level of continuous 3D print manufacturing can be achieved. Looking forward to seeing future updates and hope you make some good money off this.
This is an advancement for 3d printing and recycling as well imagine the amount of plastic that could simply be reused instead of thrown away. Do you think this would work with hemp plastic pellets to further improve sustainability and print quality?
Seems pretty cool, not much use to me but cool nonetheless, and we know why cheap pellet extruders didn't get made, it's called profit, if everyone could make their own filaments then that loss in profit would be huge Although while I see this being able to replace a lot of things there are a lot of filaments I don't think this can replicate well, specifically the dual extruded ones, this should be able to mostly do rainbow filaments if you can get the coloured pellets
If you mean with "pla" materials for 3D printing, then yes. The only Thing that is still need is a simple and cheap recycling system that everyone can afford and which lets you turn your household plastic waste into pellets for 3d printing. Have this one already planned ^^ 🙂 Do you maybe have any ideas? As an inspiration
i havent watche the video, but im sure that 3d printing companies are not too happy about this considering they make money off filament! so i doubt youll ever get big support from them. but we the people will support you
this looks great man, i cant wait till your done, would love to build one myself. i work in injection molding and have access to TONS of waste resin so this would be amazing to basically print for free!
I'm not sure why you keep talking about printing food. It's a super niche gimmick and won't be the selling point. Have you even considered what would be required to meet food safety standards? Freedom from higher filament prices and the companies trying to lock you into their ecosystem is a big deal, and makes your concept worthwhile on its own.
The sugar 3D printing is not about eating it, but making insanely cheap "Aesthetic" or low strength parts, that can be spray painted in any desired color 😄
Someone shared this on reddit and I just wanted to pop in to say how cool this is and I could definitely see myself giving this a try as someone who prints a lot of big terrain pieces on my OG ender 3
This is brilliant! all that's needed then is a shredder to shred waste PET Bottles and failed prints and I can just print with my recycled materials! brilliant! well done
This is a great I didn't know pellet existed until a few weeks ago,pellet extruders are a great idea ,I bought a 3D printer at the beginning of February so far so good, as a beginner I think I wasted almost half of my filament because of a fault with the printer and bed adhesion,I plan to make a filament maker but this also could a viable option to recycling plastics myself
I think there’s a market for manufacturing functional prints where the aesthetics are not a priority and your design would be an incredible way to cut down on cost. I imagine a company that wants to mass manufacture parts but don’t have the volume to pay for the tooling costs of injection molding. Your design could fill an interesting niche and allow people to bring things to market we wouldn’t see otherwise. Bravo. That being said, reaching the consistent density, flow performance, and quality of manufactured filament with a pellet and hopper system is no small challenge. I image it would take a high quality extrusion screw and some clever thinking to make it work in such a short barrel! Also, as much as I want to believe the powers that be are gatekeeping pellet 3D printing, I think it’s more consumer preference. When most people purchase a 3D printer, they want the things it prints to be perfect. Extruding pellets introduces new variables and is less consistent than filament. The blemishes and imperfections caused by pellets would naturally turn people off and they would lean toward buying a filament extruder. Im rooting for you and this project, I signed up to follow your progress, and I look forward to ordering one to test in the future!
This is the best 3D printing news I've heard in quite some time. I am definitely buying the kit when it gets available. I hope I'll be able to afford it 😜
@@greenboy3d How much mixing occurs in such extruder? Would it be possible to blend different materials to get new, different properties? For example, if I just poured pellets of two different colors into the hopper, would the resulting color be homogenous?
Wow that is a real game changer! Hats off to you, you are doing god's work here pushing innovation forward! As people said already companies profit off of spools so they won't support you probably but we the people will! Imagine having to buy just clear pellets and add pigment to get any color plastic you want! That would be truly astounding.
@@greenboy3d hmm, honestly i would love to see a cheap shredder project made of readily available parts to turn waste/failed prints into pellets and/or an add-on dye dosing system that will control precise dosage of dye to get any color you want
Wenn du fertig bist hol ich das Teil direkt ab, Versand dauert zu lange! Wirklich cool dass du mich aufgibst und ich hoffe deine Mühen zahlen sich aus.
It's projects like this that make me glad I held on to my old Ender3 after (eventually) moving up to an X1Carbon. I have so much waste with that thing. I could see adapting the Ender to reuse the wasted PLA for slower prints where part color isn't as important. Nice work!
The pellet extruder printers feels like it could be an amazing answer to the nurdles (actual name of the pellet) in the ocean. People can create a demand for reclaimed plastics from the ocean. Also a demand for unused/defective nurdles from companies who produce plastic products.
This is absolutely amazing. I fully expected this to cost around 1K, but with under 300€ it's actually well within reach of anyone who can afford a good 3D printer. Still, I have two reasons I'm not buying it though; I don't print that much, especially weight-wise, and I'm not willing to give the hardware aspect of printing more time and effort than necessary - with that consideration, I probably wouldn't use it even if it was for free. I'd say if you go through lots of material, buy it.
In the US you can buy pellets by the pallet load. Either totes (sorta like a cloth bag) or a skid box (pallet sized box) and an auger feed to your bin would be an awesome way to feed large amounts to a large printer.
This is a really impressive project! I hope it becomes a common thing in the future, especially since print farms need to save all the money they can. I’ve also been a bit obsessed trying to figure out how to deal with filament waste between color changes. Those Bambu printers make a lot of poop. I’m hoping we can purge material directly into usable 1.75mm filament using something like a silicone mold, but it might be easier to skip all that and just make “pellet” feeders that can consume those squiggly purge blobs. Anyway, keep up the great work! I’ll have to print and install a pellet feeder in the lab next time I’m in an experimental mood.
For the pla portion, odd question. Did you account for creep? Even though the pla for the most part won't melt but over time eith enough heat it will deform.
It will take a lot of time till you can even notice any effect from creep because the applied load is very small on the plastic parts. And you don't have to limit yourself to PLA, you can also use Nylon CF/GF for example. I just designed everything in a way so that I can also be used with PLA up to 300°C, which is not the case with most other pellet extruders... And in the end you can always just print out a new PLA part when you think the time has come to replace the already used PLA parts without the need to buy new spare parts 🙂
You did exactly what i wanted to do for ages but havent had the recources yet to actually do it, and i absolutely love what you came up with ❤ very well done mate and with some modifications (im not yet sure how well they would perform and if they would be pracical) that would basically be the go to extruder in my opinion
I'm definitely looking forward to buying this kit as my last quote for a pellet extruder hurt my feelings, badly. I'll try and be patient. Creating content required for releasing this type of kit has to be substantial. I'm getting voron vibes from this project!
You work on this pellet extruder is marvelous, simply freedom to use more materials and colors , recycling of plastic at micro level is breeze. We will support you and want to development in future printer modifications
Hut ab!! I had never looked into pellet-extruders before, but I do agree - why buy a manufactured product, when you can use (at least for some materials) the raw-material instead. Great concept and nice looking result so far - I'm impressed!! 1+ sub!
I am genuinely excited for the release of this project. The biggest advantage I can see for such an extruder is recycling failed prints via shredding and printing with the shreds directly. One design feature I'd like to see is some way to stir the material by the motor to keep it reliable. Something similar to the ARTME3D DIY filament extruder system has by using a screw.
[Update October 13th]
Working very hard right now to organize the shipping of the Pellet Extruder and other tasks related to Greenboy3D like organizing a supply of pellets for everyone and a pellet extruder wiki, which is why I sometimes have trouble answering everyone immediately.
Most parts for the extruder have already arrived and have been processed & packed for shipping, however the pellet extruder screws are still in manufacturing since this is the most complicated and costly part of the pellet extruder. I believe that the first units will be shipped out by the end of October.
Due to the additional organizational tasks related to the supply of pellets, there is simply more work that needs to be done. This includes staying in contact with many companies selling different types of plastics & watching out for good offers, requesting samples, testing them, negotiating prices, organizing the transportation of tons of plastic pellets, and so on.
These tasks also take up some of my time, which would otherwise have been spent on the Wiki/Knowledge Base platform and the guide videos.
Just a couple days ago, for example, I ordered and paid for 8,600 kg of PLA pellets, which will likely be transported to my location from Slovenia next week.
2500 kg PETG pellets are already in my possession, but more of other types are needed like:
ABS/ASA/ABS-GF/ABS-GB
PET
TPU/TPE (various Shore levels)
PA GF/CF
Additionally soon there will be a new update about the ongoing progress (including the one about pellets) 🙂
If you want to get some additional pellets along with your order then that is possible however you need to consider that, while the pellet extruder will be shipped for free there will be additional shipping costs for pellets.
However I will keep you updated regarding the pellets.
The only thing I am not sure about is whether I should also get these extremely elastic pellets I showed in one of my videos, after doing more research it turned out these were not Shore 5A, but Shore 30 (with out the "A") which is significantly below Shore 0A meaning even more elastic and flexible than Shore 0A
The only problem is that these pellets are quite expensive compared to other plastics and could only be offered for prices like 12,99 USD/EUR per kg (way higher than the other plastic types like PLA, which will probably go for 3,5 USD/EUR)
Should you have more questions or concerns please feel free to contact me anytime - I am here to help.

I signed up for your email notifications because I think you're onto something that's going to shake up the extrusion printing industry in a big way! 👍
Question: Have you already made an efficient system for recycling/shredding filament for reusable pellets as well?
Cnckitchen has a few good ones as does teachingtech if I remember right
I noticed there is no heat break in this system, how long does it take to heat up before printing and how long was your longest print in testing?
Thank you, I'll do my best to perfection it with the help of your feedback and then make it globaly available @@extended_e ❤
Big companies make a simple idea look complicated to ask for a lot of money while wise guys like you make it really simple and cheaper and show that can it be done without a lot of mystery. This is the easiest subscription button click I have ever done. Very nice, hope some day I can use this.
Thank you for your warming words! ❤
What would you like to see next? 🙂
engineering isn’t the mystery. mass manufacturing is
Neither is a mystery. It's an art@@kleanish
Maybe the bucket you empty unused pellets into is itself a modular piece of the hopper so you don't have to keep transferring over and over, and loading the machine becomes easier with less risk of spilling pellets everywhere
There are some major flaws in your reasoning. The first is that you think one guy doing it for fun is somehow better than multiple teams of engineers. Another flaw is that simple does not equal the best or good, maybe the other companies solutions were more complicated for good reasons. A major flaw is thinking this is cheaper, one guy doing it and posting about his progress publicly will not have to worry much about the cost of their time whereas a company needs more engineers and needs to pay them high salaries which then gets passed on to the customer, this also seems to be just a prototype, so whilst it may work it may need significant work to make it producible on any reasonable scale which again takes time and money.
Also there was never any mystery about pellet extrusion if you did any research at all, injection moulding machines have extruded from pellets for decades. Likely the reason that companies haven’t focused on pellet extruders is because filament extruders are generally just better. There seems to be no benefit to direct pellet extrusion other than cost and when turning it into filament first it is easier to add colour or composites. With the method shown here it would be difficult to add anything into the plastic consistently. If you need to 3D print at large scale or want to reduce costs then you likely can afford to buy a filament extrusion machine and just buy pellets and turn them into your own filament and then use normal off the shelf printers. The cost of outfitting a large print farm with pellet extruders far outweighs the cost of just buying filament or your own filament extrusion machine.
This could legitametly be a million dollar idea, and for the value that it can and I believe will add to people's lives, I feel wholeheartedly that you should be rewarded for your phenomenal efforts. Thank you so much for taking the time to develop this product and share it with the world. I wish you nothing but 100% success, financially and beyond, with the launch of your invention!
This is not his idea. There are pellet 3D printers already
They are far from cheap though, did you even watch the video?@@romantashevRT
This isn't a million dollar idea however, there were 2 pellet extruders made in 2015 at different universities in Sweden. Both were small in this regard and one of them continued making industrial machines. Very much the same design as this, however this is a bit more well designed from what I would imagine would be a passion project and a lot more time :)
Umm, nobody sees the main flaw? Colors. These small extruders can not mix properly pigments into the material. That's why industrial extruders are huge.
@@romantashevRT and you can buy them from ali
I HAVE NO WORDS, THIS IS PROBABLY YHE BEST IMPROVEMENT FOR FDM PRINTERS IN THE LAST FEW YEARS
they have been around before this
This is fantastic. I hope this stays open source. I, for one, would definitely click a "donate" button on your site if ever such a thing existed.
Thank you for your warming words! 😊
Regarding the "donate" button 😅, I have a Patreon account, which you find in the description
This will make testing 3D prints so much easier since i can do more tests and I won't feel bad about using a large amount of supports anymoe. All the waste can be just ground down and reprinted.
Yes but you need to keep in mind ground print waste is not exactly same as original, while printing some substances which help make p4inting easy vaporize, so petg when ground isn't petg anymore, it's like printing pet, more stringy less forgiving
@@howabout2138Obviously _some_ plastics are going change properties once heated and cooled and not _every_ filament type is recyclable...
That doesn't change the fact that many filaments _are fully recyclable_ and with how common 3D-printers are getting, the ability to recycle even ½ of the plastics used will be *huge* in lowering the amount of plastic waste and environmental impacts of 3D-printing 💯👏
No no no no you can´t simply keep recyngling that crap over and over again, it´s not like a metal plastic degrades over time you will always have to add virgin material, probably at least 50%. But this opens up new possibilities, like color mixing, recycling, keeping material dry or drying it in real time etc.
Recyled materails test printing or print your going the sand smooth anyways sounds like a good idea for printer poop/fails seem like a interesting way to deal with it.
That is definitly the main goal with this, I only need to figure out a better, easier and cheaper, way of recycling failed prints back into pellets. What however would be revolutionary (which is also something no one even imagines about) Is that you actually could recycle you general home plastic waste like jogurt cups, bottles and so on... into usefull objects 🙂
This man is single handedly changing the 3d printing industry.
This is freaking AWESOME!
Doing my best to improve it further more with the feedback im am gathering through my survey :)
This is by far the biggest advance i have seen in years ! And the dark truth is simple : price of the filament vs pellets …
A full métal hotend with more heating power can probably print almost any material at a fraction of the cost.
Keep this up !
Thank you for your warming words! ❤
What would you like to see next? 🙂
@@greenboy3d how about carbon fiber nylon? The chopped fibers in a pellet can be longer than the ones in filament, leading to stronger parts.
How's it possible that big companies like Prusa and Bambu don't have anyone prioritising this sort of fix? Because they'd lose money on selling filament? Perhaps this will be yet another gift of open source. If this tech takes off on cheaper printers, they big boys will be forced to adopt this ASAP to avoid a mass exodus from their machines. Brilliant!
I'd say more or less yeah. I mean filament printers are cheaper and easier to make. But for many places, they can cut printer costs by shifting their profits to the filament. Just like how you can buy an inkjet printer for $30, but the ink costs $50 despite costing only about $0.10 to make.
Filament is WAY less of a rip off than inkjet, though, so I don't mind the hit too much. But I would love to have an open source option like this in order to at least feel less wasteful, and can order materials cheaply and in bulk.
It wouldn't work for Bambu since it can't change colors.
exactly.
because companies thrive on "lifetime consumers" (aka. geniuses), not free thinking individuals who can see through the curtain on the stage (of life) who could potentially distrupt the game in a heartbeat if there is an unjustified markup in retail in any market to be balanced out. if a filament costs arms and legs compared to the raw material price this imbalance will sooner or later be resolved with.
Prusa wouldn't exist without print farms and bambu makes good money on filament
Maybe it doesn't work that well, print quality is not that good, speed is super slow.
You see like there was already a cheap way to color prints before the AMS: an airbrush. But it's complicated, it takes skills, most people want to hit print from the smartphone and go away.,
You could also greatly decrease weight by using flexible shaft (similar like dremel use for example) and moving motor to upper frame. It should work pretty ok, it could cause some retraction issues as it's basically just a coil most of the time but well, maybe worth to give it a try.
I think that what you doing right now is going to change the industry quite drastically. And I do love the idea you provide to us. Thank you for your hard work.
Thank you for your kind words :)

And thank you for your warming words! ❤

Yes I also like the that it looks like a "drop in" replacement
The natural next video I think is see the extruder being loaded and printing with at least one material, then you can use different materials in multiple videos. Or course, it is part of my expectations to know how to access to the designs ad also to the metal parts of the extruder. Keep it going.
Your entire production here is incredibly impressive. Every question I had, you answered it just as I was asking it in my head. Video quality and background is great and you have an incredible new product along with links to an email list and everything?! And it’s only your second video? Mind blown dude!

Just doing my best to make the world a better place
The *entire movement* for "home-based 3D-printing" was started to make open-access small scale production & prototyping easily accessible for everyone and to allow home-based makers, engineers, & artists to be able to bring their own computer models to reality 💯
That's why I was starting to get really disheartened at seeing companies lean more into proprietary software/hardware and price-gatekeeping the best materials/newest technologies... 🤦
But seriously, you have resparked my passion/hope that 3D-printing can & will eventually reach its full potential as it was originally intended‼️😁👍
I'll do my best to achive what you mentioned :)
What would you like to see next? 🙂
@@greenboy3dPEEK for the price of polycarbonate
Nothing about 3D printing says it has been or is intended to be open source or open access, that is just what you want it to be. The point of home 3D printing is to allow people to 3D print at home, it doesn’t really matter if the printer is proprietary or open source. The first 3D printers weren’t open source and were never intended to be.
So what if more closed source companies came about? If you don’t want to use closed source then don’t use it, it is as simple as that. However you can’t deny that closed source printers are making 3D printing much more accessible, why haven’t open source printers done that yet? How is a company like Bambu Lab able to make better printers with more features that are easier to use for a better price than any open source company? If you want open source to compete then you need to help it compete, if you want the open source equivalent to a Bambu Lab printer then the open source printing community or a company need to make one. A lot of people seem to forget that open and closed source can coexist, we don’t need to choose one or the other and neither is inherently better or more moral than the other. You need to ask yourself though, why isn’t open source at the same level as closed source printers?
Some aspects I do agree with though, particularly in regards to patents. The patent system is broken and really needs fixed. We still need patents but patents for fast developing fields like 3D printing should be short, two years at the absolute maximum and you should only be able to patent implementations, not concepts.
@@conorstewart2214 Bro. Then entire home 3D printer industry started open source. Sure, 3D printing existed in industrial and high-end prototyping first. But that was inaccessible to anyone who didn't have hundreds of thousands to throw at it. The reason why so many of these companies and sub $1000 printers exist is because of open source. Just because Bambu or whatever doesn't share their design files doesn't mean they didn't lean heavily on existing open source technology to get their products out. Ever heard of Prusa? Makerbot? Ultimaker? Most of the tech that 3D printing companies that aren't open source sell (Creality, Bambu, etc) started with open source. They may not be using open source to produce their products, but they copied many of the innovations of others. Bed leveling tech (touch sensors, magnetic, etc), power failure recovery, slicer software, motion systems, etc all came from open source projects and companies.
Take the humble Ender 3 for example, a $250 printer. First off, they run marlin. Open source. The entire motion system is a copy of Prusa's i3. Open source. Bed leveling sensor, a copy of the BLTouch. Open source. OK, so they designed their own control board and extruder, big deal. The entire product and the very demand for it would not exist without Josef Prusa's original i3. And that wouldn't have existed without the RepRap movement, started by Dr. Adrian Bowyer.
The entire reason why this industry exists in a way that normal people can access it and use it is because a few people figured out how to do it cheaply and at home and shared that with the world. If that had not happened, I fully believe that 3D printing as a hobbyist industry would not exist. Without the maker community, only large business would be doing any type of 3D printing at a cost of tens of thousands at the very least.
@@conorstewart2214I agree on two facets
1 : open & closed source "can coexist", if you as a private entity want to make and sell something without telling people how it works that's your right. However, that doesn't mean it cant be socially or culturally discouraged, it just means you should have a legal right to do it. Calling someone random on the street a dickhead is a legal right, and it should be, but it still makes you an asshole.
2 : patents are broken. I'm dubious on the idea of patents in general, but I could be convinced they're a necessary evil to some extent. (Generally I fall more in line of the camp "if you don't want people to use products in certain ways, YOU can invest in trying to stop them, but the tax payers aren't your enforcers", so DRM, trade secrets, etc. are all fair game, but if someone leaks the code, reverse engineers it, cracks the DRM, etc. thats also fair game, thus things can reach a natural and stable equilibrium) With that said, I've seen some ludicrously simple patents that aren't even a design or design concept but just a vague idea, and they still don't expire for decades. IMO "vague idea" patents shouldn't last more than a year, "I can see the innovation there but thats pretty bloody simple" can last 2-3, "alright, yeah, thats fairly unique" ~5, and "holy shit, yeah, this is pretty huge and could be big" ~7.
Businesses getting to a market first already have an insane competitive first-move advantage and can grow their market niche by making their products better, you don't need two decades of forced exclusivity too. Esp. since many new ideas are fairly logical progressions based on the cultural collective unconscious. A lot of the "unique ideas" you had were probably had by dozens or hundreds of other people because they originate from the same core ideas currently prevalent in the cultural zeitgeist. In other words, chances are without a patent someone else would make it within a few years too, but with a patent they can't without engineering around your BS.
I mean christ imagine if Apple got a patent on the smart phone. No, not the iPhone, the smart phone. I've seen patents WAAAAAAY more far reaching then that, and yet if they did get that patent they would *_actually_* still have the monopoly spineless #RtR consumers claim they do, since that patent wouldn't expire until at least ~20 years after the first iPhone was released.
With that said, you are completely wrong about 3D printing. 3D printing as we know it today was and frankly still is borderline extremist open source. Starting ~2005 projects like the Reprap started going with the explicit goal of open sourcing and decentralizing manufacturing. In fact, this started before the patents for FDM even expired. (2009) Prior to this the idea of individuals, let alone average consumers, owning a 3d printer was fucking laughable. We're talking hundreds of thousands of dollars here, these were exclusively industry targeted devices.
3D printing is a market niche that was conceived, incubated, birthed, developed, educated, graduated, and is now getting a full career in Open Source. Additionally proprietary offerings rarely do much all that special, with open source offerings almost always being generally better except for, again, patents.
Closed source has a right to exist, but that doesn't make it good. If people are willing to buy what you are selling every party involved has a right to make that transaction, but that doesn't mean what you're selling is actually a good product or is even better than alternatives, it just means that, for one reason or another, your customer wants it and is willing to buy it. Eating 5 pounds of bacon is not a good idea, but you are just as free to sell 5 bounds of freshly cooked bacon as you are to buy and then consume 5 pounds of freshly cooked bacon. (Or buckets of cheese)
Had an similar view of this happening soon to 3d printers while I work with plastic injection and have been producing pellets for long time. I find your minimalistic screw pellet struder very intrincate and yet simple. Am looking forward on your development...this is real engineering at its finest. Open up already a Patreon or something.

I used to work in the molding industry for nearly a decade and gave you a more detailed answer than you probably asked for.
interested in your work, product, and where this thing goes!
This is brilliant! You’ve inspired me to release some of my designs.
I have a lot of respect for you making something like this free, and it’s clear this was made out of pure interest and drive.
How does retraction work with this? Does running the screw in reverse suck the plastic back in?
yep, I'll demonstrate that in the next video 🙂
I’m more impressed by the auger than anything else. The rest is just fitting parts to a motion system in an organized manner.
This is a nice extruder, looking forward to seeing the end-product, maybe even one in my hand.
But the price of pellets varies a lot. Yes, if you go for the plain plastic pellet types that are used in the plastic molding industry you can get very cheap stuff. But most of the well known filament brands have additives to make the plastics more 3D printing friendly and while they do sell the pellets too, you pay premium prices for this (about 50% of the filament price when I looked around).
So pellet extruders make the most sense on larger printers that are used for high volume production jobs. I still think that using a pellet extruder on a consumer or prosumer style printer is a nice thing to have.
Thank you for your warming words! ❤ But there a couple of things you oversee, because there are not obvious
What would you like to see next? 🙂
True about the material - but the real kicker here is recycling. If you only use Prusament, you could shred your misprints, feed them into your pellet printer and use the stuff instead of throwing it away. I thing that scenario is much more interesting than the pellet printing as such.
Amazing extruder, the gravity fed Hopper really simplifies the design, and is a really great decision to focus on the extruder.
I can't wait for this to come out to the public. Put me down for three of them.
What would you like to see next about it? 🙂
@@greenboy3d
I want to see more videos of it in action please. I wonder if it can be made smaller? I wonder if we can push manufacturers to make the PLA beads even smaller. let's start a revolution. On the premise that this idea will save energy costs for everyone.
I want to know if I can get the STL file for that drive screw. Grouches on reddit seem to think that drive screw will be impossible to mass produce for a reasonable price, I think that it wouldn't be that complicated. @@greenboy3d
Thank you for publishing the details of your design. This should help protect you from any patent related issues, since you have put the design in the public domain. I do hope this design is more widely adopted, and even if I would buy pellets for most of my "cheaper" prints, I'd still buy filament for some things.
Retraction is why it's not mainstream I almost guarantee, or the lack thereof. The only way I could figure to do it would involve precise tuning to essentially "coast" to the "retraction" point and you just run out of material in the perfect amount instead of sucking it back in a little. The retraction of molten material without a fixed point to pull back from is the issue of course, maybe an air compressor but to create a vacuum instead of pressure? Idk man, this is awesome with a lot of potential!
Retraction in a filament extruder is not caused by the filament retraction itself, but by the underpresure it create. And our atmospheric air pressure then presses against the remaining molten plastic through nozzle hole preventing it for a short time to ooze out until the presure levels balance themselfs
What would you like to see next? 🙂
With Pressure Advance the need for retraction is significantly lower, and with some plastics, retraction almost barely works anyway, PETG for example. Pressure Advance should work the same way with this pellet extruder as it does with a filament extruder. I run 1mm retraction on my direct drive converted Ender 5 Plus, and pressure advance (running Klipper) and it works pretty well with PETG, very well with PLA. I dont print esthetic parts though, only functional stuff where I prioritize strength over looks so run low cooling and high extrusion rates with high temps, neither of which helps with looks :D
Assuming we have a suitable shredder for unwanted prints that could be used with this system, I'd say this is a massive win for the environment! Amazing work! I am looking forward to seeing how this develops further.
amazing work !
I'm looking forward to the release and possibly mounting this to my Prusa mini !
Thank you for your warming words! ❤
What would you like to see next? 🙂
Very clever engineering, well done! Does this work with the new generation of high speed FDM printers. I would imagine the extra mass on the print head would be a major issue when these printers run at such high start and stop accelerations as well as keeping the pellets feeding at these high accelerations. Also will the resonance compensation algorithms still be able to account for the mass of the print head/feeder.
This is amazing! I am looking forward to seeing this implemented!
And thank you for your warming words! ❤
What would you like to see next? 🙂
Don't worry about print quality. People will play with settings to improve it. Just the fact that you got it to work is amazing. You have my respect!
I can see why for hobbyist-level machines, manufacturers have little incentive to push for pellet printing - especially since they also usually sell filament spools themselves.
But for large print farms that go through hundreds or thousands of kg per month, it would be a big boon, and some of them even develop their own printers.
How come they didn't develop this tech yet? Would be very curious to hear your take on that. Thanks!
I have already a video planned for your mentioned topic "How come they didn't develop this tech yet?" 😀
@@greenboy3d Very exciting! Looking forward to it.
I think the main reason stopping most people is the inherit flow consistency issues that come with pellet exteiders. Pellets aren't the same as filament and there are always going to be some amount of gaps between pellets which causes inconsistencies in flow which are much more difficult to tune for. With most designs I've seen, it takes a good amount of experience and time to be able to produce an acceptable product with pellet extruders
@daliasprints9798 this is the way.
@@daliasprints9798I'd say a combination of increasing pellet pathway & decreasing pellet size is the route to optimize👍
Even though it takes more processing to get smaller pellets I'd wager the its still ultimately much less processing to get 2mm pellets than it is for standard filament! Not too mention smaller pellets = faster more efficient heat transfer and melting when extruding and ultimately if you can feed/melt pellets in the screw at a rate that equals or exceeds extrusion rate, then the inconsistent extrusion due the pellet gaps will be all but eliminated 💯
I want to buy it! So much of my printing is exploratory, I am already using recycled PLA and am always looking for more cost effective solutions for my prototypes. Excited for your product launch!
soon you can
Awesome! Are you going to be releasing the design for download along with links to purchase the non-3D printable parts?
Thank you for your warming words! ❤ All 3D Printed part will be for free and the other ones come in form of a Kit
What would you like to see next? 🙂
Can't wait to see more development on this system. Anyone operating a 3D printing business should be very interested in this system. Well done!
TIME TO LAUNCH MY FRIEND. You should be shipping development kits already. Most people are still tinkering with filament extruders. Why grind up material and extrude it only to be fed back through another hot end, just buy/ make pellets and feed them. Ender 3s are $150 in the US right now. I want the metal parts ASAP! Also the tech you have been developing. I could buy a commercial pellet printer but that's many times the cost. I want a sub $300 (total printer cost) printer on my bench tomorrow. Your solution seems more refined than most. Release at 80-90% refinement or lose out. Perfecting your design is taking too long. I've read many of the comments and those folks don't seem to recognize how close you are to a breakthrough solution. I would love to see the PLA tech first and then the TPU after that. Please ignore the "critiques" below. I've been following 3D printing tech since 1986 when it was first invented. You have a game changer here, just get it deployed.
Thank you for your words :)
Launch is planned for this June
What would you think would be a reasonable price?
Depends what your plans are. If you plan to sell a assembled product, 2.5-3 times what the base cost is. However cost of scaling desighns and creating a distribution network and the cost to humanity if the design is stuck in IP prison for 30+ years would be prohibitively expensive and just be repeating the same mistake every designer of this pellet system has yet to fall into. Instead of you sell affiliate link parts kits and a tutorial on a platform with advertisements you could avoid such issues and save yourself headache of calling manufactures and distributors with extortionate cost to entry and mitigate. A lot of countries just steel patents anyway. Sling Shot Chanel has a great vid on the hassle and lawyers involved for mediocre results. Maybe though if you mass adoption and mass donation you can set up your site (agian with affiliate links) a “pay what you can system” with a recommended amount. It scales well with viral content and I’m sure the people won’t mind supporting the original Prometheus and calling out people who don’t credit if you do it like that. You can even add a few (are you sure you don’t want to donate?) links in the web page flow just to give people a reminder. It’s not scummy to ask for support if you are doing humanity a service and it’s pay what you can.
In short open source with your web page. Web page has your tutorials and affiliate links to make your parts kits. The site has advertisements on it and a “recommended donation amount”. Then add pop ups in your web page flow saying “are you sure you don’t want to donate to the inventor of this product?” “Are you really sure? Not even 3 dollars?”. But if they make it through the pop ups, it is a “pay what you can” system for the affiliate parts list including 0 as a option. Though the adverts and affiliate links should compensate you even for the people who just go to download and refuse to support regardless. This is good and you get clout for open sourcing and guarantee best prices. Maybe you could even sell merch or have a “#(your pellitPrinter name)” so others can easily post links to your page in copy cat comment sections.
@@wastelesslearning1245lol he is charging $600
I like poeple that put their effort to finding solutions. I would not buy expensive pellet extruder as I do not print much but for your extruder I would pay. Great job, keep on ! Looking forward to further progress and other inventions !
Great video keep up the good work!!! Can't wait to do that on my 3d printer (KLP1)
Thank you for your comment ❤
This is absolutely fantastic!
The first question I have in mind is how retraction is handled by the system, and the impact it has on print quality so I subscribed to your channel and will look at your other videos.
Thanks also for making the video so educative and describing the typical challenges with pellet extruders. I loved how simple is the solution to swap pellets 😃
Could this same method be used as a standalone device to make spools of filament? It seems like you’d retain basically all the benefits of using pellets, but you are still able print regular filament, and can use it for multiple printers without modifying all of them
You wouldn't need anything as complex as this to do pellet extrusion for filament. Filament extruders are FAR easier to make as you control the filament diameter by how much you pull the extruded material. Many think you extrude at the final diameter, but you actually extrude at a much larger diameter, and you pull it as it runs through the cooling bath to get down to the target diameter. Some will use gravity to control the diameter thickness, but those systems are much harder to tune to get a consistent filament diameter.
haven't tried it yet, would want me to do it? 😄
@@greenboy3d absolutely, this seems like a great idea
This is so, so cool I'm going to try and build one as soon as I get my printer up and running again. Being able to use pellets would be so awesome for a bunch of ideas I have
You, sir, are freaking awesome
DU BIST DER HAMMER KRISTIAN!!! Ich danke dir!!! Eine geile Idee nach der anderen haust du hier raus, machst das Leben von vielen Menschen einfacher und hilfst somit der 3D-Druck-Welt sehr Weit voran zu kommen. Du solltest am Ende evtl. noch erwähnen, dass nach einem Umbau nur die E-Steps eingestellt werden müssen, da die Übersetzung anders ist als mit einem Filament. Zu deiner Einschätzung am Ende würde ich sagen - viele Drucker Hersteller produzieren ihr eigenes "teures" Filament, ich denke allein durch diese Tatsache gibt es wenige Ambitionen zu so einem Pellet-Extruder, denn dann würde diese Einnahmequelle für sie verschwinden ;-)
Das sehe ich genauso. Und die meisten Ingenieure o.ä. denken oftmals viel zu kompliziert. Da sind "Hobbybastler" meistens effizienter. Ich bin auch schon sehr gespannt wann der Extruder rauskommt und was er letztendlich kostet.
@@joherberth9230 Lol ich bin gespannt wie viele Ingenieure du kennst .... Eine Firma muss ein sicheres Produkt für Vollidiot liefern die sich nicht verletzen können oder ihren Hamster drin backen, ein Hobbybastler kann eine PLA mouting plate rausbringen obwohl man schon heute weiß, dass es Schrott ist da PLA einfach ein kack Material dafür ist, aber egal wenn man es nach 200h wieder neu druckt und dran bastelt im Hobbybereich spielt das keine Rolle. Hobbybastler nehmen einfach keine Rücksicht auf Bedienerfreundlichkeit, Sicherheit, Dauerlauf etc.
Danke für die inspirierenden Worte ❤
Du hast vollkommen Recht mit deiner Annahme mit der 3D Drucker Industrie :)
Was würdest du gerne als nächstes sehen?
@@greenboy3d sehr gerne, du hast es verdient! :) vielleicht kannst du den Bereich hinter der Schnecke, wo man das Granulat sehen kann / raus holen kann, etwas runder und etwas trichterförmiger gestalten, damit die hinteren „Pellets“ besser vorne raus flutschen können, dann muss man hinten nicht so rum machen mit Werkzeugen.. ;-) ich habe dir bereits Anregungen über deine Website zu kommen lassen.. Zum Beispiel um den Antriebsmotor nach „Extern“ zu verlagern, in dem du eine Biegsame Welle / Biax dazwischen schaltest, zwecks der Kraftübertragung.. :)

I love this man. I'm brand new to 3D printing, so I can't provide sugestions, or meanifully contribute to the convesation. I just want to offer my encouragement, I think this is a really wonderful and helpful project!
Please keep working on this, I will absolutely be building a printer to use with this once I have enough experience to know what I'm doing!
Thank you for your kind words, I will absolutly keep working on this 😀
What would you like to see next? 🙂
next thing you know you will design a pellet dryer to either integrate into the hopper or have a separate dryer hopper that feeds the main hopper. then you can also add pigment directly into the pellet mix. you know just like a pro industrial extruder
You could "reinforce" the hopper with silica gel that is going to suck up all the moisture in the Hopper keeping pellets dried :)
What would you like to see next? 🙂
actually you could run heater pads on the sides of the hopper walls, do to the distance of the hose and hot air rising out of it , it should create a natural circulation of air including some vacuum from the bottom of the hose or chamber of the extruder@@greenboy3d
this guy is responsible for the biggest breakthrough in 3d printing
The Chinese are going to put up a clone for sale just based on this video alone. Hurry up with the release so that you can get a part of the customers.

I'ts amazing to see what you've achieved with this project and the potential impact of this is huge! With this mod and a belt printer like the Creality CR-30 a whole new level of continuous 3D print manufacturing can be achieved. Looking forward to seeing future updates and hope you make some good money off this.

This is an advancement for 3d printing and recycling as well imagine the amount of plastic that could simply be reused instead of thrown away. Do you think this would work with hemp plastic pellets to further improve sustainability and print quality?
Seems pretty cool, not much use to me but cool nonetheless, and we know why cheap pellet extruders didn't get made, it's called profit, if everyone could make their own filaments then that loss in profit would be huge
Although while I see this being able to replace a lot of things there are a lot of filaments I don't think this can replicate well, specifically the dual extruded ones, this should be able to mostly do rainbow filaments if you can get the coloured pellets
And thank you for your warming words! ❤
What would you like to see next? 🙂
I want to experiment with materials for 3d printing batteries, and this will make it 10x easier. Amazing work.
so people can basically make their own pla using household products?? checkmate
If you mean with "pla" materials for 3D printing, then yes. The only Thing that is still need is a simple and cheap recycling system that everyone can afford and which lets you turn your household plastic waste into pellets for 3d printing.
Have this one already planned ^^ 🙂
Do you maybe have any ideas? As an inspiration
This is so clever. It will potentially allow a lot of different color and material blending not previously possible.
i havent watche the video, but im sure that 3d printing companies are not too happy about this considering they make money off filament! so i doubt youll ever get big support from them. but we the people will support you
What lovely words ❤
If that couldn’t be stopped, they will try to monetize
this looks great man, i cant wait till your done, would love to build one myself. i work in injection molding and have access to TONS of waste resin so this would be amazing to basically print for free!
I'm not sure why you keep talking about printing food. It's a super niche gimmick and won't be the selling point. Have you even considered what would be required to meet food safety standards?
Freedom from higher filament prices and the companies trying to lock you into their ecosystem is a big deal, and makes your concept worthwhile on its own.
The sugar 3D printing is not about eating it, but making insanely cheap "Aesthetic" or low strength parts, that can be spray painted in any desired color 😄
An infinite supply of those breakable prop bottles would be awesome.
Someone shared this on reddit and I just wanted to pop in to say how cool this is and I could definitely see myself giving this a try as someone who prints a lot of big terrain pieces on my OG ender 3
Thank you for your kind words ❤

@@greenboy3d I'd love to see how it handles bridging!
This is brilliant! all that's needed then is a shredder to shred waste PET Bottles and failed prints and I can just print with my recycled materials! brilliant! well done
This is a great I didn't know pellet existed until a few weeks ago,pellet extruders are a great idea ,I bought a 3D printer at the beginning of February so far so good, as a beginner I think I wasted almost half of my filament because of a fault with the printer and bed adhesion,I plan to make a filament maker but this also could a viable option to recycling plastics myself
I really like how you thought about everything, including easy replacement of pellets with the other color or material. Nice German engineering here 👌
I think there’s a market for manufacturing functional prints where the aesthetics are not a priority and your design would be an incredible way to cut down on cost. I imagine a company that wants to mass manufacture parts but don’t have the volume to pay for the tooling costs of injection molding. Your design could fill an interesting niche and allow people to bring things to market we wouldn’t see otherwise. Bravo.
That being said, reaching the consistent density, flow performance, and quality of manufactured filament with a pellet and hopper system is no small challenge. I image it would take a high quality extrusion screw and some clever thinking to make it work in such a short barrel! Also, as much as I want to believe the powers that be are gatekeeping pellet 3D printing, I think it’s more consumer preference. When most people purchase a 3D printer, they want the things it prints to be perfect. Extruding pellets introduces new variables and is less consistent than filament. The blemishes and imperfections caused by pellets would naturally turn people off and they would lean toward buying a filament extruder.
Im rooting for you and this project, I signed up to follow your progress, and I look forward to ordering one to test in the future!
This is the best 3D printing news I've heard in quite some time. I am definitely buying the kit when it gets available. I hope I'll be able to afford it 😜
Thank you for your comment ❤
What would you like to see next? 🙂
@@greenboy3d How much mixing occurs in such extruder? Would it be possible to blend different materials to get new, different properties? For example, if I just poured pellets of two different colors into the hopper, would the resulting color be homogenous?
Wow that is a real game changer! Hats off to you, you are doing god's work here pushing innovation forward! As people said already companies profit off of spools so they won't support you probably but we the people will! Imagine having to buy just clear pellets and add pigment to get any color plastic you want! That would be truly astounding.
Thank you for your warming words! ❤
What would you like to see next? 🙂
@@greenboy3d hmm, honestly i would love to see a cheap shredder project made of readily available parts to turn waste/failed prints into pellets and/or an add-on dye dosing system that will control precise dosage of dye to get any color you want
Wenn du fertig bist hol ich das Teil direkt ab, Versand dauert zu lange!
Wirklich cool dass du mich aufgibst und ich hoffe deine Mühen zahlen sich aus.
I’ve literally been saving my PLA scraps for years hoping someone would do this… can’t wait to finally have it
It's projects like this that make me glad I held on to my old Ender3 after (eventually) moving up to an X1Carbon. I have so much waste with that thing. I could see adapting the Ender to reuse the wasted PLA for slower prints where part color isn't as important. Nice work!
Thank you for your kind words :)
Pure brilliance !!! 👍👍👍
Thank you for your kind words 🙂
The pellet extruder printers feels like it could be an amazing answer to the nurdles (actual name of the pellet) in the ocean. People can create a demand for reclaimed plastics from the ocean. Also a demand for unused/defective nurdles from companies who produce plastic products.
This is absolutely amazing. I fully expected this to cost around 1K, but with under 300€ it's actually well within reach of anyone who can afford a good 3D printer.
Still, I have two reasons I'm not buying it though; I don't print that much, especially weight-wise, and I'm not willing to give the hardware aspect of printing more time and effort than necessary - with that consideration, I probably wouldn't use it even if it was for free.
I'd say if you go through lots of material, buy it.
Thank you for your feedback 🙂
In the US you can buy pellets by the pallet load. Either totes (sorta like a cloth bag) or a skid box (pallet sized box) and an auger feed to your bin would be an awesome way to feed large amounts to a large printer.
Never even knew something genius like this existed. Looking forward to further developments!😁
Thank you! 🙂
What would you like to see next?
This is a really impressive project! I hope it becomes a common thing in the future, especially since print farms need to save all the money they can. I’ve also been a bit obsessed trying to figure out how to deal with filament waste between color changes. Those Bambu printers make a lot of poop. I’m hoping we can purge material directly into usable 1.75mm filament using something like a silicone mold, but it might be easier to skip all that and just make “pellet” feeders that can consume those squiggly purge blobs. Anyway, keep up the great work! I’ll have to print and install a pellet feeder in the lab next time I’m in an experimental mood.
Brilliant. This is the future of 3D printing. Subscribed.
For the pla portion, odd question. Did you account for creep? Even though the pla for the most part won't melt but over time eith enough heat it will deform.
It will take a lot of time till you can even notice any effect from creep because the applied load is very small on the plastic parts. And you don't have to limit yourself to PLA, you can also use Nylon CF/GF for example.
I just designed everything in a way so that I can also be used with PLA up to 300°C, which is not the case with most other pellet extruders...
And in the end you can always just print out a new PLA part when you think the time has come to replace the already used PLA parts without the need to buy new spare parts 🙂
😔 I wish I had time to play with my printers and develop fun stuff like this. Great job!!
You did exactly what i wanted to do for ages but havent had the recources yet to actually do it, and i absolutely love what you came up with ❤ very well done mate and with some modifications (im not yet sure how well they would perform and if they would be pracical) that would basically be the go to extruder in my opinion
Fantastic ingenuity! Best of luck finishing this project. I would be interested in this for a Bambu p1s.
I'm definitely looking forward to buying this kit as my last quote for a pellet extruder hurt my feelings, badly.
I'll try and be patient. Creating content required for releasing this type of kit has to be substantial. I'm getting voron vibes from this project!
You work on this pellet extruder is marvelous, simply freedom to use more materials and colors , recycling of plastic at micro level is breeze. We will support you and want to development in future printer modifications
Thank you for your feedback!❤

@@greenboy3dPrinting multiple materials and recycling ♻️ different materials with different 3d printers
Hut ab!! I had never looked into pellet-extruders before, but I do agree - why buy a manufactured product, when you can use (at least for some materials) the raw-material instead.
Great concept and nice looking result so far - I'm impressed!! 1+ sub!
Thank you! 🙂
What would you like to see next?
I am genuinely excited for the release of this project. The biggest advantage I can see for such an extruder is recycling failed prints via shredding and printing with the shreds directly.
One design feature I'd like to see is some way to stir the material by the motor to keep it reliable. Something similar to the ARTME3D DIY filament extruder system has by using a screw.
There is no stir necessary
What would you like to see next? 🙂
Excellent works. There are good ideas there specially where you could save costs. I wonder how the retraction works though!
Thank you for all of your hard work and everything you’ve done it is very appreciated by the community 🎉
