This guy is out here single-handedly revolutionizing 3d printing
But I couldn't do this without your great support and from the community 😊
yeah this seriously is an insane leap in tech. it really is going to change everything.
Don't be that excited! People like CNC kitchen had done more before him! Ignorance makes you think that's a revolution is underway... Use the search form!
how is this revolutional ? its a pellet extruder. they have been on the market for a long time
@@greenboy3dextruded wax would be amazing for making molds... who needs a metal printer if you can crank out a wax print into casting sand and dump molten metal in half the time.
NASA used a similar technique to cast some of its early rockets
1:36 so the truth comes out
CAUGHT ME SO OFF GUARD OMG
more reason to get a elgoo giga... /s
sex toy industry is about to go extinct
Out of the closet. And onto the printer
I had to play that back like wtf
1:35 he already knows what people are going to ask, and the way he casually mentions it was what really caught me off guard
😅
You know you really should publish research papers about your process, optimizing a novel additive manufacturing process is the kind of thing people do for a phd thesis
I think there will come a day where we realize a LOT of science/engineering online content should be published in a more official manner. Lots of real progress happening.
@@LimabeanStudios the publishing industry shut that down a decade ago. in the EU at least. everybody in academia is too busy making money selling publicly funded research.
@@simonschneider5913 afaik everyone is always open to submit a paper anywhere
This guy has the most relevant videos on hobby 3D printing. I have no clue how i found this channel but bruh you are a genius keep up the good work.
Not only in hobby era i think.
5A!!! That is wild! At 30mm³/s? Wow!!! You're making excellent cases for your extruder and I really appreciate all the videos. This use alone could justify the mod for some people and uses. Love the material mixing experiments too. Keep up the great work!
Your extruder is perfect for the newer huge machines from elegoo for instance.
Hell yeah, yuuuuge 3D prints dirt cheap
bet they already copying it
We probably won't see pellet extruders from 3D printers companies because a big chunk of their profit comes from filament rolls, so projects like this are really helpful and must be supported
It would be actually hell a lot more profitable to sell branded pellets, so it's not the main reason.
@@SergeiSugaroverdoseShuykov Yes and no. Yes, these companies could add pellets to their product line, but no they still don't want to do that. The process would be a huge cost for a lot of those companies, since they don't own pellet making machines or have the institutional knowledge required to operate those machines. There are also other factors that neither of us would know of that would incur great costs.
@@kj9004 plastics are sold as pellets, you basically only need to repackage them
There’d still be a lot of markup between pellets sold in 1,000 kg lots and those sold 1kg at a time. That and offering profiles tuned exactly for their pellets would entice a lot of people to buy the name brand. A huge factor would be that there’s a big difference between printer-brand spools at $25/kg vs generic at $13. If it was the difference between $2.50 vs $1.30/kg though, I’d just buy the name brand for peace of mind.
This is why this guy deserves all the support we can give him. I think I simply buy one of his early extruders for that reason. A big middle finger to the established 3D printer manufacturers. Build these types of printers or go extict. This extruder has too many advantages to ignore.
He should get his extruder in the hands of CNC Kitchen. Stephan would be an enormous help.
An advantage not talked about yet is that the material will be of better quality as it suffered one less heat cycle when turning pellets into fillament. That has to be a factor considering recycling used fillament is so hard to do. ergo, prints made by pellet extruders must be easier to recycle.
Finally, if screw extruders are better for injection mould machines then it might have advantages in 3D printing too. Again CNC Kitchen could shed some light on this.
9:07 "Hello, Clarice!"
😟
from the looks of it - best pellets-/granulates-extruder ive seen ever on a 3d-printer so far! makes me almost proud to even watch! :)
At least best cheaper offer (I assume). All the commercial stuff is huge, and over 15 grand
Try using PETG with the tpu, PETG is much better with tpu
This could be the smoking gun that gets my ender 3 back from storage. This looks fantastic
I gave my ender 3 to my dad second last Christmas. Have to take it back...
My Ender is my primary printer, but this gives me an excuse to build a CoreXY FDM printer and convert the Ender to pellets.
@@StevenPeterson1 Yeah, who cares if a print takes 4x longer but is 1/10th cheaper?
I love it what you do to 3D Printing industry! Thanks for being awesome and so smart 🙏🏻
Love the idea of reseeding old 3d prints and reuse it again, this is how it should be, bravo!!! Start a kickstarter for this!
My new favorite 3d print guy, hands down
Big thing I learned from this, octopus can run on walls apparently 😂
Great inovation! I have to try it as soon as it released.
Hey bud any updates on your Pellet extruder release? This could be a huge change to the industry! The Change that we all need!
Soon There is going to be a very big update, especially for those that are in my email list and answered the survey.
Just finished creating a full Website and so... :)
I loved the home science aspect of this video. Nicely done!
Really good work!!
Thank you :)
What would you like to see next?
Yup, extrudinaire originally showed it to me, it is very remarkable what pellet extruder can do
I love your experiments!
the fibrous TPU/PLA hybrid remid me of CNC Kitchen's TPU core PLA which had amazing toughness
I think there's something worth exploring here
I want you to try 70% PLA / 30% 75D TPU this should make something close to wood's cellulose/lignin ratio and should somewhat mimic it's properties
Love to see your work
Thank you for your kind words :)
What would you like to see next?
Hmmmm you make excellent points. 5A TPU would be ridiculous with a filament extruder. Heck, even 85A is already a pain. Keep refining this please!
Great idea and really cool idea for flexibles
Very cool! great discovery!
Thank you for your comment 🙂
I am a 3D Artist And I have a suggestion for you, the swirl should have extended arm’s, up in that pallets compartment which will push the pallets toward the center of that rotating part pushing it down this way chances of failed print because of lack of pallets will decrease
The quality of your TPU prints is amazing. I am now having ideas that would probably be way too expensive right now, but having a dual head 3D printer both with your pellet extruder. One extruder has the extra soft TPU and the other PLA. You could print those dummies that are shot by gun youtubers with a 3D printer like that.
I converted an old 700×700×1000mm cmm a year or so ago to a 3d printer/cnc machine and have been looking for a print head to make for it. This is the perfect solution I think! I just have to sort out the build plate.
Keep up the good work !
Thank you for your coment 🙂
What would you like to see next?
@@greenboy3d I hope you find a team to support you in developing a new leading standard Machines !
In general TPU gets added to PLA to make silk PLA, probably a very small amount just to make it shiny
I can't what to make it, and use it. This is amazing. Instant get powdered paints for instant RGB and colour 3d printing, glitter for effect, etc. or open plastic recycling service with 3d printing. As for mixing PLA with TPU, it can be used for scenario where if something breaks, it doesn't break completely.
I was going to ask about flexy filaments! The current extruders are not good, you have to print very slowly. I am glad to hear that this pellet extruder does the trick!
Impressive, and will definitely have a great use. Image having this extruder on a Prusa XL as one of your options and combining it with traditional extruders in one print!
谢谢分享！非常精彩的节目！🎉
With every Video I see about your extruder I want it even more
7:05 _30mm³ of 5A TPU per second_
*gesundheit!*
that is game-changing for TPU! think printing cushions or entire mattresses for sleeping. kudos. can't wait to use this!
"entire mattresses for sleeping" 😂
just being able to throw out hybrid filaments is so insanely useful, I almost wonder why we ever bothered with filament
Would be interesting to test out foaming materials. LW-pla and foaming tpu come to mind.
For certain people, printing with shredded plastic rather than filament could be pretty useful. I really love the idea of being able to print 5a tpu, but I'm not willing to do all that workand sacrifice strength for it. I will say as a SLA printer owner I really like the idea of mixing plastics in an fdm printer. I'd also like to see some polypropylene and ASA or ABS mixed.
This is insane! Are you going to make a video on how to DIY one of these extruders or sell the extruder?
yess he will soon
You are changing the game. You are setting yourself up to be a very wealthy man.
Usually these type of inventions just get copied by a bigger company and the original person gets no credit and no money
I love when peoppe invent random stuff and it works very good
Extraordinary quality for the printing speed and elasticity of the material! I didn't hear about what the TPU materials is though in the video - is there a link to this material? What about the huge amount of smoke in the video? I can't imaging that would be healthy inside 🤣
I hope it’s mostly water vapor
@@hellothere6627 I hope so, but the lack of bubbles in the extruded material (which would be likely if the pellets had absorbed a lot of water) seems to indicate maybe no? 😬
One process reliability thing that’s super important is drying your pellets. Pellets have a greater surface area than filament so it Will absorb moisture much faster.
And also dry much faster.
Yep
damn this is amazing, my friend recently asked if I want to buy his ender 3 V3 SE but wasn't really sure what id use it for as I'm happy with my Neptune. if this will be available for the SE i'll for sure grab it off him and be waiting till it's out.
funny you mention spitballs, we were shooting (pla?) pellets out of beanie babies through pen tubes over 20 years ago :').
9:09 out of context this is wild
1:36 in context is wild
Try mixing TPU with a soluble material like PVA or HIPS. If you dissolve out the soluble component, you could potentially achieve a much lower apparent Shore value, assuming it prints smoothly and has good interlayer adhesion.
suggestionsforpelletprinthead"
1 plastics are moisture sensitive. Might be good to have a way to keep the pellets in the head dry.
2 big injection molding machines have variable pitch lead screws to increase the de-airing capability and the injection pressure.
3 a smaller motor, side mounted, with a gear reduction for higher torque and tighter control might be good.
Smaller pellet delivery pipe maybe with something in it to prevent clogging?
I want to use it with my bambu carbon X1. Not a lot of extra room in there.
Heyoo! Will it be possible to make this system for a Bambu lab A1, or is it impossible due to their more closed eco system? I’m about to get a new printer and definitely want to make this upgrade happen at some point!
Wouldn't it be a good idea to also put an fume extraction near the nozzle to get rid of the fumes? (not all of it)
The fume extractor could be a ring duct but sucking air in istead of blowing air out and
the cooling fan duct blowing cool air from above the fume extractor down.
I was writing a comment about making a TPU-PLA alloy when you showed it! It would be interesting to research it further until you find the right parameters (temp, speed, mix, ...) and send samples to CNC Kitchen to characterize its properties
I'd say that this one is crucial for large volume 3d printers, 1kg/3kg spools look ridiculous on massive 3d printers.
Also this is very good for recycling, you can just shred your own failed prints and print again.
I was waiting for this for a long time, unfortunately I don't want to tinker anymore, so I'll wait until this goes mainstream.
Well done!
Sooooo... can i get the files for this extruder or shall i attempt to build my own?
Just tell me when I can purchase and I’ll be there waiting
Working on it
have you thought about another motor? i wonder if theres something better than the standard NEMAS...would require a nice BLCD controller and firmware, but theres potential i think...
@@simonschneider5913 NEMAS have too much unnecessary metal on, but for now I don't know any better motor
@@greenboy3d can you tell us about the range of rpm youre running it? I am exactly of the same opinion about the NEMAs as you are! are you familiar with the rolling-screw-extruder designs? they run a usual brushless with quite high rpm. but i guess thats too much here...and then i was thinking about if there are cheap and precise cycloidial gears to buy to make torque out of the usual high-rpm-brushless motors perhaps?
[starting to think about it, the oozing and firmware tweaking to stop it when using high-rpm-motors make my head spin already.. ;) ]
@@greenboy3dMoons/LDO?
You should test how good the extruder mix the pellets, use colourless with a very small amount of coloured TPU (or any other plastic but the same type for both), then you can check the part on how good it mixed the pellet.
I worked in injection moulding, and even there you could get in trouble (when using coloured pellets instead of powder) because when you have a very low ratio (1 colour/30 clear) the screw can't mix it well.
In these cases you could just extrude a filament, that you shred and use again, to keep colour consistence.
Mixing different sorts of plastics, is quite difficult as all have different optimal melting temperatures.
I'm interested in even softer stuff like TPE-S, (SBCs, SBS, SEBS)..
Bo 😂like that you kept the flubs, makes it more entertaining
Think maybe next you should try adding some milled glass/carbon fiber. Subbed, working on my own extruder, just on an e3 belt kit.
Great work Bo!
Thank you! :D
Seeing this makes me so happy. Not because i am amazed by the engineering. But because this makes me feel, there are still some clever and willing to to people in germany left .... :D keep it up man!
that soft TPU looks almost like a real octopus when you squish it :O
It looked like there was a lot of steam being produced during the extrusion of the TPU in the start of the video, how hard do you think it would be to integrate a pellet drying/dessicating solution to the pellet feed? It seems possible, but more difficult due to the larger volume of the transfer hose, and the printed parts.
This is so cool. I’ll be waiting till a kit or something can be bought. Will this be able to be used on a creality ended 3 v2 neo. I have it sitting around and would be a fun use for it
Amazing! You could make some money with this idea.
My hunch is you either purchased the screw or made it on a lathe. If you want to make a reciprocating screw with a small back diameter and large front diameter, that works via friction as much as heat, use a CNC Mill with a 4th axis on the table. Or just buy one! haha
Nice man! Do you plan to release that extruder into the market? I think there is big market gap for this!
This is really cool!! Is your extruder able to print abrasives materiel? Like Nylon and CF or GF
i LOOVEEE this idea, and i will defo follow you more closely from now on.
I just have few questions if you don't mind
Where do you get those pellets and tubing you showed off in previous videos?
How did you make the screw and hotend block? Did you make it with CNC or had it made somewhere else?
When do you plan (if you do) releasing the files publicly?
Do you plan on making collab on this with one of the big players like Prusa or someone else?
You don't need to answer all of it, even just one will be enough
thank you in advance
I am convinced that in a few short years every printer will use pellets with an extruder like this. In fact, I am so certain that I will hold off replacing my old Prusa printer. My next printer MUST have that extruder.
Thank you for your coment 🙂
What would you like to see next?
So glad to see you are still working on your channel! As you know I even gave you $ as a patron because even a small amount might help you get your Chanel started
I have been working on my own channel but not ready to put up because I couldn’t edit them yet, hopefully soon!
Coincidentally my husband took my elastic bands from my blood draws to use for slingshots!
Thank you for your support and your kind words 😊
Filament manufacturers nightmare. Amazing.
Would it be possible to mix wood fibres and hot glue, to 3d print mdf?
I would be interested in seeing how well this handles high volume fraction composites. Typical filament becomes excessively brittle as the additive ratio increases, but the pellets should help alleviate this if the material is premixed before extrusion and would theoretically allow for some interesting applications that typical filament extrusion is incapable of doing.
Or you could possibly do metal 3d printing by printing mostly metal "sand" but including just enough plastic pellets to make it all stick together. Then sinter it in an oven.
@@celeron55 I have seen that done with bio-style pressure driven extrusion so that you can use an elastomeric binding agent or high viscosity liquid to suspend the metal particles. If the thermoplastic has sufficient binding strength to retain the particles in large volume fractions, I imagine that what you are describing would be viable but I imagine that you will need a pretty significant volume fraction to be able to post-process sinter the part and get a serviceable lattice of the remaining metal.
it will literally eat the extruder. like in injection molding, fiber reinforced is hard on the cavities.
@@simonschneider5913 As long as you aren't printing some 450 C space alchemy plastic, you can case harden the auger and just use a hardened steel nozzle or polycrystalline diamond nozzle if you really want to go for abrasion resistance. If you are going with the PEEK style nerd plastic, there are tool steels that can be be hardened and stay at sufficient temperature to print without annealing.
@@galacticscalepenguins6092 ok sure, then you go ahead!
Do you have any idea yet of when you will release the first version?
3D PRINTED STICKY HANDS LETS GOOOOOO!!!
Really excited to see this extruder to hit the market. 3-d printing is so exciting to see new tech coming constantly.
Thank you for your kind words :)
What would you like to see next?
Easiest sub button press ever, keep this up dude.
Thank you for your comment 🙂
What would you like to see next?
@@greenboy3d I read in some of the other videos about a secondary hopper that heats/dries the pellets to make it on par with what an industrial extruder would do. I think this is probably the next logical step.
Wow really cool extruder
And put it on a toolchanger like prusa xl
Would be very cool to have like pla core with a tpu exterior
Very interesting, do you plan on commercialization of the extruder?
Will there be a kit?
well, This looks all great, but the same question again, When can i buy one!
That pla-tpu amalgam might be awesome as an adhesion interface layer between tpu and pla in a 3d print, just need 3 print heads I guess?
Maybe this way we could 3D print also with PP or PE much easier
Should I try this out in one of my next videos?
@@greenboy3d oh yea! Like maybe you could fill the screw with hot melt glue for the first few layers of a raft, then your main material is HDPE
How does it handle finer-grinds? Like right now you're feeding standard pellet sizes, but the poor PLA mixing got me thinking the blend of TPU and PLA was too large for the nozzle to mix more than at a surface level. I dont know how viable chopping TPU pellets would be (might need to freeze it first).
BTW: you might need to dry your TPU pellets. There was a lot of steam in the printing footage.
It really sucks that creality hasn't jumped yet on making these yet because I can see this being the future of 3D printing I want one but I don't want to modify my printer for this I want a dedicated printer to sit next to my filament one. Can you do me a favor and test your printer recycling random stuff I am really interested in how printing with milk jugs will go and how it looks?
He has already made adapters to fit it to a standard Creality mount, so you could just buy an Ender 3, add this, and have it be the dedicated pellet printer.
Will there be also in your shop option to buy some pellet? I know that it is difficult to buy 5 kg of pellet or less. And it wold be nice to have 1 or 5 kg of material in 2-5 diffrent colors.
i see that your extruder is smoking when printing, be careful because when you can see fumes that's when VOOCS are higher. please do this in vented room :)
C'mon bro I've been bullied like that story from your school just leave bad stuff out, you have a future in this field 👍
Yeah, subbed!
The point about getting a Ph.D isn't far off!
What do you mean with "The point about..."?
hmm, elegoo nepture 3 pro prints tpu just fine. at least I think 95A or something quality. you would actually try the syringe force feed extruder, where the screw is above the piston, and the whole syringe is hot melter metal chamber. and it needs some pause time to reload. but maybe the screw-only nozzle is best for continuous feed. you decide. try the stress weight test for the flexible tpu. you can make the harder tpu flexible by making hollow parts. also much lighter and less 3d print material used. separate food color as liquid or something that mixes directly with the tpu. maybe spot coloring like in a bubble jet printer head.
95A and 5A are entirely different worlds of difficult to print.
want to try wire spot electro-plating on a metal 3d print surface. copper or zinc wire. yep true metal 3d prints at home easily cheaply simply.
If everything mixes in the screw I am wondering how you purge the extruder properly to use for the next material
Hello how did you get flexible tpu pellets thx
Great work! Can you do a retraction in this type of extruder?
Yes, I talk about it in my Video "Stop buying Filament, Use this alternative instead"
In all seriousness though I wonder if a combination approach would be more effective. In terms of mass at the hot end anyway.
So the hopper creates a filament from the pellets and the extruder uses an extruder screw instead of traditional screws. This could reduce hot end mass by half at least as the screw could be much smaller.
Now I want to see TPU+ABS :)
I want to build one of your pellet extruders so badly!
Soon you can :)
@@greenboy3d :)
1:36 I know this is the internet but that caught me off guard...
Well, this topic is more popular then you might think... 😃
I like to think about it as dough. When you want to make good baking, you have to mix dough thoroughly, otherwise you might get chunks of different, and not very pleasant parts of it to eat. You will probably never achieve better result by just mixing this in the extruder itself and probably have to pre-process pellets differently. This is still a great success so far and I am watching you closely. Keeping fingers crossed for you mate
😘
What if you shred pla pellets with blender? Would it give worst or better results? I mean, you should then have smaller and more consistent air gaps so everything should be more cobsistent but idk
The smaller the pellets/granules the better. Which you use a blender, coffee grinder or something else. It it just a tool to turn plastic waste in small "3d printable pieces"
There definitly better ways, but those "blender" methods still work to some degree 😇
This idea might finally solve the elastic pressure suit problem.
This would be really cool with pneumatics as well. Balloon-Shaped cavities could be used like mussels.
