3D printing with granules and recycling plastic waste...
I need your feedback about my extruder, Please answer this super short survey ➡ greenboy3d.de/
My mission is to create a low-cost system, that allows everyone to 3d print with pellets and to recycle 3d printing or plastic waste into anything through 3d printing. And this channel is all about this mission, it's progress and it's possibilities.
3 big milestones need to be achieved:
1: ✅
Is to create an inexpensive and universal 3D-Pellet-Extruder and to bring it to the world of desktop-3D-printing, so that every Maker and 3D-Printer-Enthusiast can get a taste of the significant reduction in printing costs when printing with pellets and all the other benefits...
2:
Is to create an inexpensive machine that turns plastic chunks into small plastic granules, which can be used for 3d printing with the Greenboy Pellet Extruder.
3:
To spread the word about 3d pellet extruders and their capabilities to recycle plastic waste.

Why use blender to shred 3d prints??? Mmm micro plastics
Why u cant just do new filament from recycled grains? Then you can use it in normal printer.
You can, but this is more difficult than just directly 3D printing with grains
Hello, after watching this video I was immediately very happy that there is a new way to cheaply print your products. but later, when I started to be interested in pellet prices, I had to be disappointed. Did I not find cheap pellets for sale, or does the author of the film buy standard filament in coils at a very high price and that is why he has such a big price difference for raw materials? for example, I pay £9/kg for Petg filament in rolls, and I found Petg pellets the cheapest for £7.5/KG. because of such a small price difference, it is not worth rebuilding your printer.
My bet is that getting the pellets in Australia would cost about the same as all we have are scrounging lazy middle-men importers trying to squeeze as much as they can from us rather than a 15-30% markup or any local manufacturing. #LudditeNation
Most excellent vid
this is the future!
Recycling is great, but filament does not have such a big price. Question is reproducibility/fail rate etc. Standard noozles is must, as custom ones give you disadvatage on market. In future I think you will have problem with spreading of MMU option. Over all like idea.
what do you mean with "spreading of MMU option"?
@@greenboy3d Multi Material
So extra hardware board is needed along with some firmware and software/driver to make the extruder work. This can’t be a simple swap out of a filament puller whose mechanism is a bit different. Looks nice but cludgy. Wonder if this will become a thing, ie option for 3d printers going forward.
Never said you need extra hardware board or some extra special firmware. From a mechanical perspective things work different, but from an electrical perspective things as exactly the same...
I dont like too much all the "green" theme, but i like the idea of self-sufficiency, i might use recycled plastic for low quality prototypes and only use top quality expensive filament for things that i want to be more permanent and of higher quality, i am a fanatic of quality by the way
9:00 of all the colors to use.
well.. what can I say? 😅
@@greenboy3d i dont care at all but the lefties will crybully blackface and cancel you.
would grinding the pellets into more of a dust give you a more consistent flow rate compared to larger pellets?
Yes it would
I love what you got here. The problem is layer lines. I would like to see this mod on something really good with that. If it's your system then open-source it to see how you can compress it. Current superchargers come to mind with compression.
Make sense for large production (dozen kilos per day), for printers with 1mm nozzle at least. If you still wish to print as is, make your own filament. In current state it's too much hustle and errors to use it. And don't print things which you can buy (usually it cheaper, stronger, last longer and don't require hustle).
You won me at the 8:41 . Now I want a 3d printer just to be a brat.
😀
I would probably still prefer something more akin to filament maker in shape of regular 1kg spool :D - that would require no change to printer hardware ... at max somehow sync filament demand and production rate (some humor included :) ).
"dildos and toy vaginas" im glad youre honest about the fact that thats guaranteed to happen.
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!
amazing
when you made that hook I immediately recognized it being the cnc kitchen one lol
Maybe I should sent it to him for testing
This might be a really good idea I will look into this Although i must say having worked as both a baker and a chef, that 3d printed donut idea doesn't sit very well with me.
You should check out the quantum delta 3d printer by Kilian Gosewisch, instead of moving the printhead it moves the entire bed on all axis and the extruder stays stationary, that way you can eliminate the size and weight constraints of your extruder.
Make an adapter for your propriety "nozzle" that has multiple SKUs for every nozzle thread type. Boom done. Really cool idea man.
im sorry what? yorue telling me i can stop printing my bedroom toys in 95a shore hardness TPU???
indeed 😅
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... :)
spray painting raises cost and time quite a bit. I have a question: why does using pellets reduce print quality?
I recommend you to watch my First video "Pellet vs Filament 3D Printing" kzread.info/dash/bejne/c4dsm5qBaamWZNY.html I explain the reason for this in it
Hey Bro, Can I get the BOM of metal parts and it's specifications?...
have send you an email
$20 for a spool that can last me multiple months never felt like much. Reducing that saves such an insignificant amount of money that I don't see it as a factor when I think of this. It's still a cool concept though. Being able to cut out making spools of filament alltogether would save a bunch of energy and resources.
I don't mean to sound overly-negative. It just feels like you are focusing the most on price when that's the least significant aspect of filament to many people.
@@Spencer-wc6ew oh my friend :) It is a significant aspect for many people
Look up “Nordson hot melt extruder nozzles” we use these at my job. their prices can be a little steep for some parts since they sell to factories but I believe that’s the kind of nozzle you’ll want to swap it with while still being available. But I’m not sure. They even have a lot of stuff to work with pelletized materials, but that’s extremely expensive but the individual replacement bits are cheap.
Pellet swap mechanism? Like during print.
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 😇
Will you need custom firmware because I have that exact same printer and will try and ake this as soon as it comes out.
You can use any firmware like. For example, Marlin is the firmware I use. You just need to adjust some very minor settings in the firmware in order to use the pellet extruder on your 3D printer. But don't worry I will make very detailed tutorials regarding this, which will everyone to upgrade their 3D printer to a pellet 3d printer 😀
Any more questions?
@@greenboy3d Yeah would i be able to grind/shred failed prints and support material and reprint it in this extruder setup? Also would you be able to grind things like PET bottles to recycle them directly into new prints?
I think the nozzle should be optimal for the process however if you can make it so the nozzle is easily swapped so the user can choose, that might be best. Seems like this system would be great for prototyping where you may not be worried about print quality however I would question whether the print quality is good enough for dimensional accuracy.
this is what big filament doesnt want you to know
😶
Faster and better alternative, mold a block and CNC that into shape.
As a plastics department student, I can easily say that every time a plastic is broken, its properties decrease by 15%. For example, if you break a plastic that can withstand a load of 100 kg and reuse it, it can withstand a load of 85 kilograms in the next test. Additionally, print quality begins to decrease. This is an average value and varies depending on the plastic, considering that there are more than 3000 types of plastic in total. good luck
Wouldn't it be 85 kg if it's a 15% decrease from 100 kg?
@@russiannpcbot6408 Yes, you are right, I just pressed 7 instead of 8. mistake
Extrusion to print head is never going to be worth it. There is no cushion to maintain even flow hench, the heavy layer lines. Better to extrude to a filament spooler. You would have to work it so there is a little back pressure to act as a cushion to keep the filament an even thickness. Do able though...
I recently got a Magneto X printer, and your work seems tailored to using it as a test bed, since the linear motor can move some serious mass quickly.
Great inovation! I have to try it as soon as it released.
Your Project is awsome dude! When will you release this extruder commercialy. I can't wait while thinking about how cheaper I could produce my products.
The only defects I'm seeing is like you stated the nozzle pressure not being controlled (k-factor). I'd think simply reducing the thread length (basically a short stub nozzle) would change variations drastically. To add would also need to reduce the overall melt zone temp as well increasing feed so the pellets aren't in the melt zone too long. Just food for though
I’m all for recycling and reducing waste, also I like saving money, so I love it! Most prints just don't need good quality. Stuff like hooks, holders, storage containers and so on work just the same even with a +-1mm tolerance, so the reduced surface finish is no problem.
Cool thing to print with a very hoght temperature pallet nozzle. Lava, 3d printing with lava that will be super cool, but you need a nozzle that can warm up to 3000 degrees celsius wich is way too hot for a combentional printer, but it will be cool to make an oxidian 3d print
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.
The sad reality is filliment industry is a source of income for so many people.. This video is a sign gor all of them to invest in something new
after this video, if I were buying new 3dprinter, your extruder would be one of my main considerations. I've got couple questions tho. How compatible this design is with enclosed 3dprinter (like many bambulab clones)? How sensible is switching back and forth, if I wanted to do most of printing with pellet and go back to filament for parts, I want to be really nice?
1) Technically there is no problem using it on an enclosed 3D printer, however in such case either a bigger enclosure is necessary if you want to you use my gravity pellet feed-hopper, or you install an air pressure based pellet feeder for which you don't need to extend the size of the enclosure 2) It is not sensible in the sense of changing the printhead from Filament to Pellet back and forth if that is what you are asking.
@@greenboy3d 1 it makes sense 2that was, what i was asking. Thank you for quick and sensible answers
Thanks a lot for sharing this and hoping to get one when it becomes available. Not a pro and just started to 3d print. Would the dust be a problem with the opening on top of the extruder? Just asking out of curiosity.
There an even more improved Version now, which has a dust cap for the opening :)
Where can I buy cheep PLA pellets? I have a filament extruder and use it to recycle filament. I can extrude pellets, but I cant find a shop where I can buy pellets under €8/kg (max. 100 kg)
How well does it work with the cht nozzle. That would probably help with the oozing because of the extra resistance
Hey dude I i support what you're doing and know your legit but you should probably stop using the "the industry has a dirty secret, but I'm not allowed to tell you" shit as it's a common scammer tactic and gives people the wrong impression of you.
I feel like the stepper motor would pose more of a heat risk then the hot end if the heat break portion has been done right, them 💩s can get pretty warm 6.6
