Stefan, PLA is compostable (in very special conditions) but not biodegradable, definitely. To compost, PLA requires temperatures over 65°C + high pressure + high concentration of specific enzymes, otherwise, it only degrades possibly into micro plastics, like others thermoplastics. And there's no way you can find these three conditions into nature or into a garden waste ground compostage. You need an industrial or laboratory environment which both involve heavy machinery and energy. And last 2023 studies leads to the same conclusions, alas. By the way, there's currently no sorting facilities for PLA which is, like most of plastics currently incinerated with other materials. Please document yourself on the topic and beware about hoax which are by numbers on the net. I would like the community be more aware of that. There's currently no printing material with no impact on the environment, alas.
is 0:48 a shot of i70 in Colorado?
@@axelSixtySix i could not have said it better!
Hey, i have noticed that when you shred the plastic, a lot of it sticks to the machine due to static buildup. Coincidentally this problem also exists when crushing coffee beans so people spray the beans with water to reduce the static buildup and thus the clinging to the walls of the machine. You might give it a try since you already gotta dry the filament afterwards :)
A little hint. When producing PLA filament, an elastomer such as EVA (for example, TPUs such as Ninjaflex should also work) is often used to make it less brittle. 5% is enough.
Thanks for being one of the few channels that actually talk about recycling or the pla issues in general! Even though this still seems too difficult/expensive for most, it's vital to shine a light on it.
yeah, because we need lot of this deranged cultist thinking. same pattern - create imaginary problem, try to solve it at great costs and waste and then expect praise. Grow up and get real
Agreed. I would really love a place nearby where I could drop my unused prints and waste knowing that they would create new filament from it.
@@_renze_ - Do you think it would be viable to ship your plastic to be recycled into filament? I was running through the logistics of it all, as I could likely set up a super small operation and use the proceeds of reselling (super cheap) recycled filament to scale.. but I'm simply not sure how viable it is to ask folks to ship it out or whether I could even keep up if I got more than expected at first.
In the US, you can just put box in your local grocery store and ppl will collect things for you. I'm getting one full box of HDPE plastic caps in 2 months. Shipping is cheap in the US, it'll work. In the EU shipping is super expensive.
It's got to happen at some point. Governments dont have a plan ever. Someone has to do it
It would be interesting to see you do some iterative strength tests by starting with virgin plastic and then extruding, testing and then grinding it to extrude it again and see the trends in the strength metrics as the number of melt cycles increases. This could potentially help determine by comparision how much virgin plastic needs to be added to recyled material to reach certain strength thresholds.
Totally agree!
I've seen some studies on this done. the problem is that it's not the grinding and re-extruding that is the primary cause of weakened plastic, but things like prolonged uv exposure and abrasion. I know that injection molded plastic can be ground and re-injected dozens of times without a noticeable strength decrease, but virgin plastic that sat outside for a year will be noticeably weaker when ground and re-used, as the polymer itself is what has degraded.
I'd also like to see how the name brand cutlery filament does in the usual testing gauntlet with and without food exposure with 100% recycled material. maybe throw in some poorly washed stuff if you think the recycling setup isn't going to be damaged by it.
Brothers Make did a video on how many times plastic can be recycled
i think it was interesting 😊
I would hope you wouldn't fuck any of the plastic but hey you do you
I would love to see you turn more complicated old-prints into new filament such as polycarbonate, tpu, and petg. I love this "series" because it truly shows just how much 3D Printing can impact the world not only through building, but through recycling as well.
Congrats, you won some of the filament I made! Please send me a quick message at contact@cnckitchen.com
I work in injection molding hopefully I can help with some mixing percentages. For most of our materials we have anywhere from 4%-6% for color hopefully this will help with color consistency. As far as regrind (recycled plastics) go, we change % based on how much scrap we have. Recycled plastic has generally already gone through a heat cycle and the polymer chains do break down causing a less viscous melt. This could be why your diameter for your recycled filament wants to stay undersized but when virgin material is added the diameter increases. If you want to do a 15%-20% Virgin added to regrind, then maybe stepping up a nozzle size on the filament extruder and running a slightly hotter melt. This hopefully will help with filament diameter and a more homogeneous and consistent melt and color. As always do what you do best and experiment for the best results. I just hope this helps put you in the right direction.
If you use the used plastic cutlery you might even create some exciting new variants of scented filament.
Dog breath benchy.
Interesting😃
Nah fam
danm thats a good comment
Using hdpe from shampoo and cleaning agent bottles makes for some amazing smelling materials. Hdpe is basically a sponge for odors
What about plasic containers from take out food? It feels like a logical next step! As always, good job Stephan!
If it's #6 plastic it can be used just like Shrinky-Dinks! (The other ones, not so much)
On my school project in Germany btw that's what I used. And you won't need an industrial shredder. You can slice lids with scissors and use the blender to make it to a smaller fraction. With a shredder it's faster though.
I love that you've really taken this on! I think the biggest blocker for slightly wider adoption is the cost of the shredder still. It'd be cool if there was a cheaper option that performed well, or perhaps you could look into designing one?
I just separate and save my scraps and send them to my local recycler and get back nice new rolls. It’s always exactly 1.75 and comes with an engineering and material property report.
Since they have a system and infrastructure it is basically the same price as getting rolls of cheap filament, but much higher quality, as I give them good plastics.
If I was to make this myself, just for my labour, not any equipment, each roll will cost me $300 instead of the less than $30 that I pay for a professionally recycled one.
If it’s a hobby and you have time, it’s great. But I have already spent weeks of my life, trying to make good filament. It’s not for me personally. I learned all that I wanted to learn and sold the equipment.
@@lemonsquareFPV Really wish there were more recyclers around. Completely agree with you that an exchange program is a better use of everyone's time.
The shredder and extruder are both individually more expensive than the cost of filament spools for most hobbyists (I have barely spent more than $100 on filament in my 3 years of owning a printer), and professional users might not see any cost savings after quality control and recycle costs are factored in.
@@dsp4392couldn't agree more! Recycling centers could be turning all kinds of plastics into filament
It would likely never be economic for a single hobbyist, but a local makerspace might be able to pay it back by selling their recycled filament
Been really enjoying all the recycling videos! Keep them coming. I think it would be good to mention that most plastic cutlery is made from PP and PS and not PLA.
On a related note, PureCycle is a PP recycling company that finished their first large-scale plant in Ohio earlier this year.
This isn't just a US problem. Asian countries have the most plastic waste in the world. This is a huge opportunity for reuse worldwide!
China and India account for 80% of the great pacific garbage patch. But you won’t hear that covered on CNN or MSNBC
You get better engagement when you say it's a US problem.
Not really, you can´t collect all that stuff easily. It costs more to sort, clean etc than just create virgin material. We have the same problem in the automotive industry which we ciurrently work on, but the material is just not a good as virgin material and costs even more money.
@sierraecho884 it even extends beyond recycling. Almost all renewable / clean things we need will be more resource or effort intensive than the old pulluting things they replace. But we still put in the effort!
@@AnnaVannieuwenhuyse This is factually wrong. Recycled Aluminium is waaaay cheaper and easier produces, same goes for any other metal. It´s also easier to collect, sort, etc. Solar an Wind can be very cost efficient as well. I don´t want to be mean but you have simply no idea what you are talking about. Sounds like you talk from a more political correctness point of view.
Not long ago this kind of at home recycling seemed impossible and expensive. This is really pushing the curve and i find it incredibly impressive. Hopefully this will become something anyone can add to their hobby.
Just do a whole series where you work your way through all the most common short life or easily broken household items. Plastic plates, cups, soap bottles, shampoo/conditioner bottles, combs, tooth brushes, ziploc bags, etc.
Id love to see you shred and 3d print whats in your recycling bin! Im loving these videos and hope this turns into a series because it gets me excited to see what absolutely amazing things 3d printing could do for us
You did the plastic silverware. Now try the plastic food containers, trays, cups, etc. Love watching your channel, always interesting new things to see and learn!
Not gonna lie my main issue with this is the shredder. It would be interesting to see a good way to shred the plastic for cheap
I would think a coffee grinder might do it. The low speed type with ceramic disks that baristas use, not the blender models.
I don´t make new filament but i recycle plastic with other methods and a classic mixer is the best cheap option
@@sail4life
@@sail4life I think the hardest part of trying to use a burr grinder is getting the plastic through it. Coffee beans tend to get kicked up as it is so getting the plastic to go through the grinder on its own would be, I assume, a challenge. Then again, they make hand-driven and non-electric burr grinders. I guess you could figure out a way to attach one of those to a surface and then turn the crank with one hand while feeding the plastic in with the other hand? I really wish in-home recycling from start to spool was as inexpensive and available as 3D printers are though.
You are knocking these home recycling and filament making videos out of the park! Can't wait to see where you go to next with this. ❤
I like the random horizontal banding and even more banding effect would be a very nice option.
The evenness of the blending of the red Masterbatch was very impressive from such discrete pieces.
Shred a ton of old CDs oder DVDs. Leave the metallic particles inside
Good one! Glittery Polycarbonat Filament
Too bad 3D Printing and recycling wasn't big when recordable CDs and DVDs were in their heyday; the coasters would have been great for this purpose.
I wonder if the organic dye layer in record able cds would effect the polycarbonate base material... Can that filament maker that you used get hot enough for polycarbonate?
@@Sembazuru guess the stuff get burned away and mostly carbon stays.
@@Sembazuru It uses PTFE tape on the nozzle so no, not without modification. I've also read that pure polycarbonate is very hard to print; the filament you can buy generally has additives to make it easier.
This looks awesome for the use with single use plastics! Though, CPLA is quite uncommon for anything else, isn't it? Could you give Polypropylene (PP) a try, too? Many packaging materials are made from it and it has some really interesting properties.
Heads-up, polypropylene and any other polyolefin is far from a beginner friendly filament.
These recycling videos of yours have to be my favorite ones! Awesome experiment and idea!
I’d like to see some testing on recycled ABS material from old car parts and maybe yard equipment? Maybe old electronics too? This could be a big source of material!
You should try recycling the Prusament spool material, that way you can combat the waste that comes from sending the extra spool plastic with every roll of filament!
I’m totally interested in this extruder! I can see so many opportunities to create usable filament from recycled post-consumer waste plastic. 😊
In Sweden (and most likely the rest of the world) we use polypropylene for ice cream containers etc. It would be really interesting to see how those recycles. I might even buy me an artme extruder if it goes well
Excellent video as always. Your attention to detail is impeccable.
I absolutely love your channel! I've learned soooooo much from you. I started #3Dprinting back in 2021 on a Ender 3 pro, your channel was my first 3D Print channel sub. Anyway, I'd love to see you recycle TPU (if possible) with different color changes, and different hardness levels. Thank you for such amazing info, all your hard work, and high quality (visually pleasing) videos. Keep up the amazing work Stefan!
Thank you for another very interesting video Stefan! I'd love to see PET bottles recycled with your setup.
Not going to work. Shredding will take him for a loop)))
I think this is a very promising idea. I hope to one day get a filament machine like the one you have. It seems awesome.
It's not expensive 600 euro, made in Germany.
Stefan has always been one for progress and environmentalism. Thank you for all you do. Good, important work, and highly entertaining.
Love this series on recycling this stuff, keep it up!
I think I remember you mentioning HDPE a while back, but I would love to see if you can recycle that, or perhaps go into ways to blend or even treat prints of various types to have increased UV resistance. It'd be an awesome help to the community, in my opinion, especially to those who want to print products specifically for the medical field, since we use UV to sterilize a lot of our equipment.
Love the channel, love what you do, and the way you succinctly present information is incredibly refreshing!
Using recycled plastics for medical purposes is a horrible idea.
@@DaveSmith-cp5kj Out of curiosity, why? I would think recycled plastics would be fine for anything that is already made from the same plastic but I really don't know much when it comes to medical.
@@JoshDavis40 It's the sterilization issue. If you want something reusable it has survive being autoclaved which pretty much none of what is commonly used is capable of without warping due to glass transition. Compounding this is the fact 3D printing introduces an insanely high surface area for contaminants to be trapped, which increases the risk of contamination. Contamination is not very likely, but in medicine unlike say dentistry you have no idea how sensitive a patient will be to pathogens. If you watch healthcare workers if anything is suspect, they throw it out (even if they drop some gauze on the floor still in it's plastic wrapper) because infection control can mean life or death.
An autoclave also only sterilizes biological threats. You could have something like a recycled material having an allergen or something that would go unnoticed. This could be as equally as dangerous no matter how small.
For first responder applications however, infection control is not as big of a deal because the act of treating a victim in an austere environment automatically introduces pathogens. Your objective here isn't infection control, but ABC stuff (Airway, Breathing, Circulation), or MARCH if you are in military. Ukrainians on the separatist side early in the civil war before they started getting supplies from Russia did things like make tourniquets, NPA, and even decompression needles from trash which saved lives. However many had complications from the obvious lack of infection control.
@@DaveSmith-cp5kjand you are very right)
It is amazing to recycle cutlery but I don't know how you but I use plastic cups more than plastic cutlery. You could take colored plastic cups and have it colored filament without adding any colours.
I used to work in a medical production facility where we made medical tubing on a plastic extruder. There the diameter was very critical. We had a laser micrometer continuously measure the extruded diameter and via a feedback loop we adjusted for the correct diameter. The tubing was cooled in a waterbath so it wouldn't change diameter anymore before winding on a spool.
Correction was done by pulling out the material faster or slower until the specification diameter was reached. This was done continuously throughout the production proces.
I would suspect that if you can create a very stable fillament diameter the 3D printed product would benefit greatly and have fewer defects and artifacts.
Just my 2 cents. Great Vid!
I love videos where I yell at the screen "do this and that" and then 2-3 seconds later the person explains my very good idea and I feel smart :D Still very much enjoy all your videos, thank you for all the energy you put in.
Frohe Feiertage und einen guten Rutsch!
Old coffee machines that grind coffee beans sometimes have grinders that no longer produce a fine enough ground coffee for the machine to work properly but might be able to grind filament plastic into pieces possibly smaller than the raw pellets.
I wonder if it would be possible to thoroughly mix a finely ground mix of filament to achieve a more uniform color.
Love the recycling videos! maybe try HDPE and ldpe bottles next time, I heard they are hard to 3d print with
Fascinating concept. Thanks for sharing.
Just like my comment on the last extruder video; how does it handle ground up PET bottles? What if you first make them a bit smaller by putting them in a convection oven to let them deform? Also would like to see something like PP and HDPE post consumer waste getting shredded. You are a gateway for quite a few people into homemade filament Stefan, and I can’t thank you enough for this
The red filament looks like it’d be perfect for some mesa terrain pieces. As for suggestions, I’m somewhat curious what effect mixing different materials has.
I haven’t made much effort to sort my printing leftovers between PLA and PETG since I don’t have a recycler, but supposing I did have one would the mixed materials work at all or just make a useless spool?
You'd probably end up with a useless spool, unless you managed to sort them. PLA has a low melting temperature, so you could sort the PLA from the other material by putting it in an oven at just high enough temperature to make it soft, and then squish the prints to test the material.
PLA and PETG absolutely do not like each other, they form virtually no molecular bond, so you would be relying purely on mechanical interlocking. PLA and ABS do work together quite well though, so I imagine PC might work too since PC and ABS work together. PETG happily bonds to TPU and Nylon to a lesser degree, so some impurities there shouldn't harm the result too much. Definitely a nice topic for more research!
I would absolutely love to see a company take this idea and insert it on a large scale! Great job
'Recycling Fabrik' in Braunschweig, Germany. Amazing guys. The only ppl in the industry who really helped me with my falling out recycling project in German school plus Naomi Wu (she is AMAZING). I wish Stefan would highlight them too.
Honestly, I'm a random guy who is interested in 3d printing since I have started watching your videos. You're doing really good job bro 😊. Keep it up. We long for new videos ❤
Great work! I can't wait to start recycling my own filament.
I think the next step to this process should be re pelletizing the filament and make it into final filament. Pelet flow through the machine much more consistent and it might help with color consistency.
build another extruder and feed the output of the first into the second
Really liked this video! I would like to see a test where you printed a multicolor print only with your recycled material, and then tried to recycle the poop from that. And maybe, repeat that as many times as possible!
I truly enjoy this channel and learn new things for use in my printer. I’m trying to use plastic bottles by making a filament maker with it. Fingers crossed
I absolutely love your recycling videos and hope to see you find more affordable ways for us to do this ourselves!
Please DONT make a video about plastic bottle recycling since a lot of EU countries have a deposit system. I would love to see a video about filament made from many variuos plastic mix such as PLA, ABS, PETG etc. and how it prints.
Very cool! Would love to see you try recycling the actual spools for the filament.
This is great!
Loving the showcase of the extruder.
Really interested to see if this filament extruder can handle PET as it's was more common discarded plastic.
Think a better way to put it. How the 3D printing industry has contributed to the plastic waste problem. The industry you cherish, has contributed a ton to waste, from plastics to short EOL machines. Instead you poke at the US. While other countries are unregulated and dump toxins to manufacture products that people use daily! I find it odd that the US seems to be the boogeyman, yet these creators make a living off of US based companies.
Germans just love hating on the us
a couple of counterpoints 1. there is a tone of reuse/repurposing of machines in the 3d printer industry. 2. the actual amount of waste generated by it is tiny compared to the unnecessary use of single use plastics.
@@legokill1019 - People living in their plastic bubble. Most machines are not reused they are eventually scrapped or possibly thrown away. People always seem to miss words and read other things. I said “contributed to the plastic waste problem”, no matter how small it is still an issue. It is people like you that gloss over it as a non issue. Then dodge the second part of my comment. Seems to me other countries have more of this elitist attitude, thinking their country has no faults and the US is an easy target. If it wasn’t for the US, CNC Kitchen would have to find a different source of revenue.
@@Firstleaker What's your source to say that 3D printers are scrapped and thrown away, have you personally thrown away a 3D printer or seen one thrown away? People sell their garbage 3D printers on and they fetch pretty adequate money ($50-$100 for a typical Ender-esque one) because there's any number of enthusiasts who'll happily reuse the motion system bits and the motors and the frame and rebuild the machine, either repairing the electronics and doing new firmware, or replacing or augmenting the electronics, also reusing the PSU. There also... just isn't that many of these machines around. Sure 3D printers are quite shitty and unreliable but thanks to RepRap they're very rebuildable and reusable. If i find one thrown away, i'm absolutely rescuing it.
The second thing is the byproducts of 3D printing itself, such as support and attachment material (non-use parts of the output), failed prints, and failed designs from the iteration process, as well as 3D printed items that have outlived their usefulness or got worn or degraded. This is actually something Stefan has addressed multiple times with his own recycling attempts and has pushed for improvement. There are companies popping up here to which you can mail your sorted print material for recycling and get credit towards recycled filament that they sell. This is still certainly a problem, since i have thrown away plastic at times and have seen others do that as well. I try to collect most of it for eventual recycling. It is also certainly a question of scale, since there just isn't enough critical mass to do better about it. I think 3D printing crowd is actually substantially more cognisant about plastic waste problem than the general population, and would actually be quite receptive about recycling offers if they were more available.
Seems to me you're just trolling, as you admit it's a problem that is in general fairly small in scale compared to most single-use plastic problems.
Also 3D printing is a creative endeavour. I am yet to see creative endeavours which weren't anyhow wasteful. Maybe you're just "wasting" electricity to do something that is screen bound only, but that's still coal and oil that get consumed. And yet creativity is valuable, because it's the foundation of society, culture and tech progress. Plastic cutlery or single-use plastic packaging are not valuable in the same way, no harm would come to society from replacing them with permanent, reused items.
@@SianaGearz - I can alway appreciate the long effort someone can put into a reply. Once again people tend to read what they want. “Scrap”. What is the definition of “scrap”
Metal waste or scrap metal is any product that's broken or no longer useable, which is made completely or mostly from a metal material. For example, it could be broken tools, metal sheets from manufacturing, a bent pipe, old electrical appliances. Doesn’t mean it is thrown out.
See people like you, the enthusiasts, are not typical consumers. Typical consumers live what is called a “throw away society”. Do you know when a “throw away society happened? It is the term “planned obsolescence” came into play. See, planned obsolescence started with the lightbulb. The standard lightbulb was lasting so long that manufacturers stopped making money. So all the manufacturers made an agreement that a lightbulb would have a max lifespan. Any manufacturer caught making bulbs passed a certain lifespan would get majorly fined.
People buy the latest and greatest, a year later a better machine comes out, they buy that. That old tired machine sits on a garage floor getting tossed in every corner. Then 2 years later it cannot even be sold on Facebook Marketplace. Then that poor machine is sent to “scrap” or thrown out.
Once again I said ”contribute”. Just amazing how people cannot read and blow things out of proportion!
Not everyone lives in this space, and goes by the “3D community” guidelines. People are consumers, if they get a print failure, it will go into the trash. That’s because they are told some of the filament they use isn’t recyclable.
Seems that everyone in this space lives in their plastic bubble! Literally! You think everyone thinks like you, and should think like you.
The first words was calling out a country for something not everyone does. To me that is very word of elitism. I can go down countless streets for recycling and waste pickup, there is usually more recycling than waste. I don’t pass judgement on other countries, especially if I am earning most of my revenue form that country as a creator.
If I was trolling I would be doing a much better job!
Happy Christmas, Stefan! 🎄
Happy holidays!
I'm still making my filament maker. It's gonna be a while. I honestly believe this has a huge future for 3DP and being able to use recycled material. I use recycled ♻️ filament now from a UK supplier so it will be awesome to make my own.
Valentine's recycled filament! Since you love the environment. 🥰 The finish is very impressive too. I didn't even realize that compostable silverware was made of PLA!
Nice video. Also, from what brand is the spool You used @4:38? Would make for some nice transparent drawers
I'd love to see more DIY methods for recycling pretty much any of the commonly recycled plastics (PET, HDPE, PVC, LDPE, polypropylene, polystyrene), albeit into homemade 3D printer filament or even injection molded parts (using 3D printed molds)
Investigating the use of high-force extruders for injection molding with common plastics would also be quite interesting
Pet would for sure work, not sure about the others
PET won't work. The melting temperature is 245C, not 165C. You would need more expensive extruder for PET.
learning so much from your channel thanks
Hay can you make a video on how to tell what material is what I am considering getting into this but want some help with the sorting part
This was a great idea and well executed - to me I think the key here is how to efficiently clean large batches of used cutlery, as washing them in that way is labour intensive and perhaps hard to automate. If you could shred them while dirty and clean them when in a shredded state (although maybe not something you'd like to do with your machines) that'd be a great option for industrial scale recycling.
Would a food processor work instead of a blender for shredding old filament or other plastic material you intend to recycle?
Would it be possible to use plastic trashbags as they might be able to the heatet and pulled into a filament string and what type of would be best to use?
As for what to recycle next, old LEGOs might be a good candidate, as the tires are TPU, and the bricks are ABS, and loads of them end up broken, discarded, and in landfills every day! I would love to see old bricks melted down and given new life!
Love the red. Perfect for the holidays! 🎁
Can you do a similar thing with the in between filament that is extruded from the filament maker when you switch colors?
Hi, I got a few rolls of ABS+ASA blend a while ago, and recently found out that they soften at only 60-70 degrees. Would you make and test some blend materials? My guess is that blends always have a lower temperature resistance than pure material.
I'm curious about something: I have a bunch of really old PLA that is probably not usable anymore even after drying, it is too brittle. Could this be recycled into usable filament or is it still going to be bad even after re-melting? Your video suggests that it will still be brittle, but maybe some sort of plasticizer could be mixed in to improve it?
is there any kind of plastic takeout container that can be recycled? my work orders takeout every day and there are so many black tubs. I don't know if you can print polypropylene.
How is printing HDPE? I have about 20 or 30 lbs of shopping bags from the supermarket. Could we melt it into a small chunks and shred it for 3D printing?
I work at a supermarket chain in New Zealand and I’m now consulting the deli department on collecting and used cutlery to turn into filament thanks Stephan.
I would love to see how other variants of plastic could be incorporated to a batch of recycled pellets ie; plastic bags, caps etc!
Nice results and filaments! Love the gradient red ! Can you recycle the spools of filaments ? I always end up throwing them since it takes so much space. I would love to recycle myself so I Hope that we will have soon an affordable and convenient way to do it.
How much power did a kg of material use/cost with the shredder, dryer and extruder?
Would love to see an way to recycle PP or PE containers and plastic films in to filament. The ones they usually package meat, fish and various other food products, but i really don't know how one would grind those.
Love, love this topic. Thank you for continuing to bring it to the forefront. I think a lot of us are waiting for a low-cost, easy-build, consistent solution to grind the plastics and extrude them. Also, you might want to get some moisturizer on those poor hands of yours :)
heck yah thats cool and also a very nice machine, i would like to see if you can recycle multicolor/multimaterial filaments?
great video! would be interested to see if you can then print cutlery again. Wonder how smooth it would come out
As always, excellent video. An idea to achieve the good filament diameter: Shorten the loop to reduce the weight at the output of the extruder.
What filament brand do you use for your bambu lab x1?
As far as i know the stockings are made from nylon, it will be posible to melt them to make nylon filament?
The filament recycling videos are pretty interesting and fun!
We have a lot of roundbale nets. I always wondered if it would be possible to make filament from it.
Can you make filament from leftover spools? What about fiber composite filaments?
Can PET be pulltruded and then pelleted to be used in the extruder and make filament?
i do really wonder what you do with all the purge stuff? and also how effective is this really? i mean you use a couple of machines that uses quit some power because of heating elements.. would be nice to at wich point it really would "save" money
I'd love to see you try to recycle filament spools. I think most of them are a blend of ABS and PC, so it should be feasible.
I also have e pile of empty spools laying around. I plan to recycle them, but i don't know how.
I'd love to see you do a roll of filament that changes color on purpose using scrap prints and/or bits of pelletized filament from the ends of rolls too short to print anything with. Basically, put in 100g or so of one color (or white with one color pigment), and then put in another amount of another color, and so forth. I'd love to see how the colors transition using your extruder and how well the color transition zones adhere to each other, both on the spool and in the final print.
Hi Stefan, I am a great fan of your channel. I learnt a lot of things and got success in 3d printing. Thanks a lot man. I am working on an odd project in which i wanted to calculate my laser engraving machine (DIY) laser head movement. My thinking is to calculate pulses of x & y stepper driver every fixed interval and calculate its tangent and add up its values till one job completion . As you are an expert of this subject can you suggest to me if it will work or any other method i have to use.
This is amazing, & everything I've ever wanted
King's collage London, just released a paper ("An enzyme used in laundry detergent can recycle single-use plastics within 24 hours") on a very fast method that breaks down PLA to monomers within 24 hours, without quality degradation of reproduced PLA. Its a long way from that to commercial recycling, but it shows the possibility of a much more practical way to recycle than the time consuming industrial composting.
Can you print all prusa parts needed to make a printer from recycled plastic?
Can you recycle the filament roll plastic? I have a few laying srroudn and there's not much to do with them.
Another area that i see a lot of waste is the packaging of foods. I wonder how recyclable they are for 3D printing.
Also, polyester clothing. could that be recycled into filament? Would polyester/cotton blends be considered "natural fibers" reinforced?
Would it be possible to add a cold output die to get 100% consistent diameters?
Very cool! I wonder if the plastic disposable plates could be turned into filament too?
very useful information, thank you - if you notice any affordable shredders, would you please post?
Would annealing the plastic either before or after extrusion help with the brittleness?
I want to know how many times pla can go through the process of being printed and recycled. Could you recycle filament indefinitely? how quickly do you notice degradation?
I would like to see filament recycling with composite fibers.
Mix in some shredded fibers, shredded some parts which already have fibers and so on.
I would love to see a revisit of a DIY filament grinder to get more consistent results. I would love to make a filament maker to recycle filament at home. It would also be interesting to see you grind down some PET bottles like with the pullstrusion to see if it gives as good of a result
I have never seen a cutlery tray like the one in your dishwasher. That is amazing. I have a small counter top dishwasher and while it lacks the space for two trays it still makes my dishes very clean. Remember to add a little detergent for pre wash! 😂
Can you mix different random plastics together in making new filament?
How long from having raw material to a full spool does it take you with the Artme ?
