[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.
Hi Greenboy, I have been exploring the possibilities of a pellet extruder and large format printing about 10 years ago. Back then i put a lot of effort and research in, so i like to share the hard work i put in back then as i did not print with pellets ever myself.. What my main conclusions were then: 1) The pellet extruder is a 100% needed tool for large format 3D printing. Printing a chair would be about 6 kg of material. Costing about 3 euro per kg = 18 euro for printing a chair. GREAT SOLUTION! Instead of 30 euro per kg. (prices then) = 180 euro for a chair. (TOO MUCH!) Print a 6 kg mailbox for packages for 18€, sell em for 75 and you have a business.. If you print for 180 and want to sell for 400, that would be too expensive compared to other production methods. 2) A printer, about the size of a washing machine and slightly larger would be a nice size, because that is related to the size of the human body. Almost anything made from a cardoor to a lawnmower, sinks, microwave or table. The size is related to the human body. About 85*85*85 is a nice size. Or for example 1*1*2 meter. The size of a door. But parts can also be connected, so the 85*85*85 is actually good. 3) This would also be great for making (large) molds for composites, concrete and more.. BUT: 1) it has to be 100% reliable. Not 99%. And if the plastic stays in too long, it will clog easily. You need a clogging protection script. And a dumping basket just like the bamboo A1. When material is longer in the hotend than say 20-30 seconds, it should start flushing.. Otherwise the material burns and clogs..... Also at start up and cool down. This is really important. if it clogs once, it takes A DAY!!! to repair and the pellet extruder is financially totall loss.. Also take care about a superfast startup and cooling down time. If it takes 10 minutes to heat up and 10 minutes to cool down, there will be material in for 20 minutes, the material starts to burn so 100% guaranteed clogging. SOLUTION: A) POWER on the heater. use a lightweight, powerfull heater. Heat the barrel in 10 seconds instead of 10 minutes. Use a relais and 230 volts.. B) Use powerfull cooling after printing. Cool it down fast. If you want to keep the moving parts as light as possible, make a cooling down location on the printer, just like a material drop box, Put the nozzle in water, oil (non electric conductant) or cool with air and a powerfull fan pushing air at the righ spot.. Try cooling it down in 15 seconds. C) There should be a flush material dump at the end of the printing cyclus.. So the printer heats up with fresh, un burned material. D) start with large nozzles (not too small) so it flows easily. E) Make it easy to take it apart. 2) Experiment with fibers in the material. That can produce about a two times higher strength to weight ratio in the product.. So way better product, lower printing costs, printing the same product/strenght twice as fast. And this can also be made in a kind of envirementally friendly way. PLA can be made out of starch, bioplastic. Mix it with woodfibers and the product looks and feels like wood. Long fibers would wind around the extruder shaft, but 2? mm fibers could give strenght.. Try mixing 70% PLA, 15% flax short fibers? 15% sawdust and a spoon of arachide oid (boilingpoint at 300 degrees, printing at 210) Arachide oid makes the sawdust stick to the pellest so it mixes well and it gives a little bit of flex in the material... 3) The system should be light. Heavy motors, heavy everything could give problems. Then you also need more heavy XY motors, more heavy stepper drivers, more heavy axis, so the entire systems starts flipping over if it becomes too heavy.. SOLUTION: Make a weight strategy.. Put the pellet extruder (every month) on a digital kitchen weight scale and then start scraping every gram of. Use carbon fiber parts, use aluminium instead of steel? Ise glue instead of bolts. Use a flexible drive shaft instead of a motor on the extruder, push cooling air through a super lightweight flexible hose/tube? and save 50 grams of the fan weight? Use a light stepper motor with a cooling rib instead of a more heavy motor. Very often lighter = cheaper = better. Using less material for the extruder makes the extruder more affordable. I also suggest to use a thermal camera when developing. So you can see whats going on. 4) The heatbreak is important. The point between the hot some and cool zone should be well designed 5) The system should be silent. People run a large printer in an office, an attic, a room, a garage.. 6) The auger you use is already way better than what i've seen in my life.. 10 years ago people were trying wood augers... A well designed auger is part of the solution. I think the barrel and auger metal should be higly polished so it has less chance to stick? I think you're in the right direction of a solution. 7) The flow control is important. With filament and decent gears you can say 100 mm = 100mm but with an auger its harder to extrude excactly the right amount. If it extrudes a lot the material temperture is slightly lower, if it extruded not so much, everything heats up a bit more... My idea about this was to stabilize the temperture bu using a heated pellet hose.. The pellets go in at say 80-130 degrees. Pre heated.. Then 1) you can print faster! (allmost twice?? as fast) And the temperture is more stable in the hotend as the are no cold pellets going in. With a more stable temperture, its easier to predict the output so it also stabilizes the output. If the hotend has to bride 20 degrees - 210 = 190 degrees gap. With a 110 degrees pre heated hose it would only have to do a 100 degrees gap... And maybe doubles? the output of the extruder? Printing fast, what is a benefit if you want to print big things. 8) Find donations for the pre commercial stage... Connect to (local) industries. - Ask bigrep to donate a free printer to use (lease) for 2 years. Then send it back or so.. - Consider kickstarter.com or so.
I am not buying it for now becuse I don't really have the time to fit it among other projects but I am keeping a very attentive eye on your channel, thanks for what you're bringing to the community
I got the email on the day of the preorder, I impulse purchased it so fast, I kinda blushed a bit. I got dozens of bottles, a Re-PET machine, a filament joiner on the way, as soon as I have this, I'll be printing with 0.6mm nozzle and start printing my hydroponics kits. I hope your business becomes successful!
I saw the community post a couple weeks ago about pre orders but didn't have the money. RUclips changed my subscription notifications from all to personalized, so I didn't see this video before today. I'M STILL GONNA GET IT, who cares about a discount on the upfront price when I'll be able to crush water bottles into little pucks, dice those up to around 6mm, then just start printing?
Thank you for your kind words! I sell the whole pellet extruder, not schematics or BOM. Very soon there will be a "Wiki" on my main website, where people will be able to download more than 50 3d printable adapter for various 3D printers + the necessary 3d printed parts. And in addition to that there will be all kind of video tutorials about pellet 3d printing which will make the pellet 3d printing journey of many people much easier.🙂 Do you have more questions?
The value of this project is underrated. Thank you for your commitment! Very interested, especially adapting your parts for high temperature application. PEEK, PEKK pellets anyone? Game-changing.
Thanks a lot for your encouraging words!

I preordered on Sunday with some funds I was finally able to gather up. I'm so excited! Would you be able to maybe make a Bambu Lab A1 adapter plate? Again, super excited and grateful for all the critical thought, R and D, and self-funding you've put yourself through to make this happen for all of us at home.
Thank you for your kind words 🙂 By the way it is not to late. Pre-orders phase with 25% OFF ends on 11th August at 23:59 Eastern time (in 11 Hours) You can get it here: shop.greenboy3d.de/products/greenboy3d-pellet-extruder-v1
Awesome! i'll definitely be getting one soon. Maybe add a side mount for a BLtouch for enders so they can still autolevel. Not to mention pretty much endless recyclability options at the fraction of the cost instead of buying a 5000$ filament extruder, and all the customization that you can put into the material. I'm so happy someone is actually stepping up and giving this technology a chance, and thank you so much for all of your hard work, and wish you the best :)
Excited to see where this goes long term! I do believe this is an endeavor worth pursuing, and if I had more liquid capital and time I'd back it in this early state. For me this is exciting, but not practical currently. The pellet extruder costs more than the printer I print with, and I print so relatively infrequently (mostly designing and making custom parts for around the home) that the cost savings over time would not be worth it. Upgrading my printer entirely would go a much longer way. I'm sure a lot of tinkerers will enjoy this, but I've always preferred putting my printer to work rather than mess around with it. Hopefully enough of these tinkerers will support your endeavors so that people like me can benefit from mass production in the future.
Very interesting project. While it is not as cheap as I would have hoped, the quality it much better that the other options that are 1.5 to 2x more expensive.
depends on your filament pricing, locally i can get 1kg for 13 euro but i cant for the life of me find PLA pellets anywhere locally, it would in theory recoup the cost in a year or so of printing but availability is a concern. On top of that the project as a whole looks a tiny bit sketchy and there have been countless failed startups/ failed promises/ inventory and shipping problems and such, i'd be better to wait for proven results.
Love this! Especially for recycling your own filament this would be such a cool and sustainable method! I’ll definitely keep an eye on this and all the best to you and the project!
Finally convinced myself to support your effort by ordering your extruder! It is very exciting to be a part of that future! I must find a printer to dedicate that build to though, they all are calibrated so well...tough call.
I really hope this project succeeds for you!! While I definitely think I'd keep a standard FDM printer for detailed printing like for Props, and other items, I would be interested in picking one of these up down the road for recycling materials. I just barely got into 3d printing, getting my own printer for the first time, but I'll definitely be keeping an eye on this project! edit: Out of curiosity, could a pellet extruder in theory be turned into a filament making tool? I've seen people turn extruders into tools to make multi-color filament before, granted that wasn't easy from what I saw.
Definitely happy for you and happy for the community. I do not think this will change the market to move away from standard filament because I know I won’t but there is now options. I plan do mostly filament printers and then work your pellet extruder for the Neptune Max 4. I will use the Neptune for bigger prints with extruder and see what magic happens. Very excited when I can afford the extruder. Really good work my man!
Yeah , i feel that for smaller printers filament will still be the way to go , but larger printers will benefit of the pellet extruder the most , since it will allow fast , big and cheap prints
@@ulforcemegamon3094 Smaller printers would definitely be the way to go. However, if you can dial in the new pellet extruder with a big printer, definitely would be something to see and save us a ton of money on bigger prints 😃

Nice to see you've been able to move forward with this extruder.

@@greenboy3d definitely. I’ve been looking for something small/ contained that can just make spools of filament from pellets, but hopefully not break the bank
@@greenboy3d ya please look into it something similar to pet bottle extruders, would be helpful and much more budget friendly :)(pellets to fillament)
i do like the extruder a lot. However, I must say I am holding off on the purchase till a later point. As in my case, I am more worried about the extrusion consistency with the produced print. If I have a idex printer, I might consider buying it as a infill only extrude.
Using a pellet extruder for infill and a filament extruder for the rest sounds genius tbh , use the pellet extruder for infill as detail doesn't matter there and use filament for the exterior of the print where detail matters more
Was never gone 🙂was just preparing everything like the website, organizing the production and much more "behind the scence" stuff to get everything rolling 🙂
If you shred for example your old 3d prints into granules, then this method of using meshes works very well as I showed it in this video: ruclips.net/video/eWgzi4a1bJo/видео.html However, normal pellets are generally speaking about the same size but have due to their shape from certain angles different sizes which make proper filter almost impossible...
It is and thanks for your wishes, however there is still a lot of work to do... 🙂 Hi :) First of all I want to apologize for the late reply.

if i could get PLA pellets in greece for a reasonable cost i'd buy this, ive done roughly 2 hours of googling around and found nothing local and all abroad options have insane shipping costs (like alibaba or turkish websites)
I'm very interested. However, I am mostly interested in large scale 3d printing right now, volumes up to a cubic meter. So, I wonder: What size nozzle can you put in the extruder and what maximum amounts per seconds may I print with it?
i would love to support you by buying one, but I just purchased a house and a bit strapped for cash. Do you have any plans for when or if a second preorder round will open up to the public?
yeah we rly need a video on where and how to buy pellets. Because this is a great project but from a bit of google most pellets actually cost MORE than filament which destroys the whole purpose

If she took a patent on this idea she took a patent on stuff that was already published in Sweden in 2015. Looking through her patent her design looks an awful a lot like the prototype I made for one of the projects :D
I'm about to buy a Bambulabs printer for the multicolor capability. Could I install this on my Ender 3 V2, grind up the poop from the Bambulabs (with a coffee grinder?) and use the Ender for stuff where the color doesn't matter?
There is an adapter for the Ender 3 Neo and Ender 3 Neo max already made. I have not yet updated this on the "available adapters list" in the FAQ on my website, but it was already created. So you don't have to worry, there is an adapter for your 3d printer, and it can soon be downloaded on my website once I have built the basic WIKI... 🙂 Should you have any other questions, feel free to ask.
To be honest, this costs more than my printer did, but I'm pretty sure the added utility makes it worthwhile. I think this is the greatest advance in rapid prototype printing since the self-leveling bed. Your efforts are appreciated.
i really wish i could support you at this time! hopefully next year i can make a profit form my printers, and find a shredder to recycle my failed prints. You should really watch that Golden Boy anime, if you ever get the time! Your dedication is legendary :)
I think what you’re doing is awesome. I’m just not the target audience. I do t even have a 3d printer but I’m looking at the A1 mini. I’m not sure if that even could take the pellet hopper swap. In any case, 3D printing isn’t a hobby for me. I’m a woodworker primarily. I just want some custom parts that could be printed. But in order to break even with a $400 pellet extender I would have to go through the equivalent of $500 in filament if pellets are 5x cheaper. That’s likely more than a lifetime supply of plastic for me, probably way more. If I ever do get into this as a serious hobby and would burn through that much material it would make sense to go pellet. Of course the biggest game would be recycling the plastic infinitely, but to my knowledge most plastic doesn’t work like that? How many time can you recycle your printer poop or old parts?
Damn I really want to bite the bullet and buy this I don’t have the printer but I want to garante that I can also get this.. it’s on the pricy side especially since I’ve never had a 3D printer before and don’t know if I’ll use it enough to justify the price.. if I get it I’ll probably be using an ankermake printer but I also do care about resolution for the parts I’ll be printing and don’t know if spending hours sanding it down would be worth it since it may discourage me from using it more. Have you tried printing with resolution as the main goal instead of just it being cheaper? I know FDM printers can only get so clear but the differences in the resolution from what I’ve seen on normal filaments and the ones I’ve seen in your videos (I’ve watched all) is drastic enough for small sensitive parts to not work as intended, but the fact that the pellets mean it’s actually going to be available for me to buy without a hassle/less of a hassle is such a positive point since it’ll not just be cheaper without shipping but even with shipping costs it’s still a huge difference, besides if I have to print a mount for the new head, I as a beginner don’t have any filament to even to use in order to print that and adding it will be a big cost, since I’ll have to take out like 45$ off of the printers budget for that roll (25$ for the roll and around 20$ for shipping), sometimes the printer comes with a small spool but that’s to test print so it’s barley enough for that test print let alone having an adapter printed, and if that print fails since I’m a beginner I’m out of luck and ill have to find someone who can print it or get a full spool. The initial cost is huge now but I know it’ll go down eventually, on the other hand the new iterations/versions of this extruder will definitely improve upon its mistakes till it’s flawless but that means version 1 is going to be something aimed at the enthusiast market where they know how to tinker and adjust things without having to need someone to hold their hand with instructions.. I’m unsure when or if a second version will come out (hopefully it will) but everyone who buys a first generation of a new product will run into the first generation problems, it’s inevitable, and the second is always better, at the same time I don’t know if I want to wait another year as I’ve been looking at 3d printers for ages and at many points I was a couple steps away from owning one, one time a shop imported a couple ankermakes and posted on their instagram at like 10 am, my dad sent the post to me but I didn’t check it till 7pm, the moment I saw I called them and reserved one (they said only one left) I went to the shop driving since I didn’t want to wait for the delivery (second day since it was at night) and didn’t know if someone else will come pick it up, the moment I got there he said it’s gone and he told us to contact them later to know when they’re gonna get more.. I was so pissed off this was the easiest and closest way I could’ve owned one, it was sold for cheaper than online too, WITHOUT THE SHIPPING PRICE, couple days go by and turns out they didn’t sell them, they were confiscated, I emailed Anker asking for the supplier contact info, I was given a number, messaged them, he gave my my regional number and I gave them a call. The guy said they were threatened and they were told they’re gonna shut down their business if they import without permission again, I mean it did get into the country so how is it their problem? The website that states the illegal list of products doesn’t say anything about 3d printers, the HS code is on the allowed list, it’s confusing to say the least but it’s in such a gray area that if you’re gonna being one in you have to be dedicated and it might just get confiscated then you’re out of luck and money, unless they return it. I called customs, the criminal information directory, called the department of interior, and ended up with a number that never picked up except for a very specific timing on 4 days of the week, after a week they picked up and I asked if I can order he said yes and when it comes it’s gonna take a while for them to call me and interview me then I’ll have to sign papers saying it’s for personal use and can’t be used for business purposes, unless I register the printer under a CR, which is stupid since I could have it personal but also print for others without needing a CR because opening a CR means I need a location, need to pay, and my name along with the address will be on the public registry just to own a printer that I can print for others and get paid for that, then pay yearly to keep the CR active, or sign it as personal and if I print for others it’ll be for friends and no payment, which is unfortunate since you can make some money out of it since it costs so much upfront and longer (filament). I asked if I could go through the process first so I can guarantee that h have the clearance before buying it so I don’t lose money unnecessarily but he said I can’t do that, he did say if I ordered it then it’ll hopefully be an easy path forward and it’ll be hassle free but when I asked if that’s guaranteed he said nothings for certain but hopefully it’ll be. Confusing mess. If I got to the shop earlier, had I seen the post before the ministry of interior saw it, I would’ve had the printer, they would’ve probably come to my house to confiscate it or make me sign papers but if they didn’t id have the printer with 0 hassle and 0 shipping fees. The shop didn’t have filament, they never sold 3d printers, they sell mobile devices and accessories so they sold anker stuff, hence why they brought it, they deleted all the instagram posts about it and every time I asked them about it (before I figured out what happened) they’d act like in crazy and they never brought or had it, first couple times they said they don’t know when they’re getting more, then they said they’re never getting it, then they started acting like it never happened. People on Reddit say you just buy it and have to wait for customs to do their things, do an interview and sign papers then if you’re cleared you get it if not no clue since no one who wasn’t cleared said anything. It’s sad, but they all said importing filament is not a problem since you can just buy it and it’ll come. I remember asking aramex (or dhl I don’t remember) if they get 3d printers delivered to here and the guy said yes they get like 5 a week (or month don’t remember). So I’m unsure why it’s so tedious and such a black area, 0 guidelines and you just shoot in the dark, been thinking of getting a printer for over 4 years and trying to find a way for about 2, obviously if I just buy one I think it’ll get through which I was close to doing multiple times but the problem is if I get it and can’t get filament for cheap (without it being completely garbage and end up breaking something or wearing some part out that I’ll have to wait for a replacement of) then it’s just going to be a paper weight. Lots of people buy a ender or something cheap and established as a starter printer since they can dip their legs in the water and see if it’s a thing they want to be doing, if I’m gonna try it I’ll have to dive in head first since otherwise I’m gonna have to go through all the process again (and considering shipping 200$ for a printer is not cheap, since I’m paying more or the same just to ship it, and id rather have 1 great printer than 2 decent ones/ones that I’ll have to repair myself since they’re more “DIY” and if something breaks you have to fix by troubleshooting everything, instead of just warranty or repair by a less janky method such as more seamless process since the ender variant is pretty old with slower technology (speed wise compared to new ones). Bambu labs will be very expensive, ankermake I’ll be spending about 270 BHD on it (excluding shipping) (this is the price the store was selling it at). I even asked the local anker dealer if I bought one and needed repair if they can help they said they can’t and I’ll have to ship it to Dubai since the main supplier is there for the Middle East. I’m in Bahrain btw, not sure what this comment was it went from something to another but I think I got my point across. TLDR getting printer is hard, price for extruder isn’t cheap for a complete beginner, not sure if I will spend enough time to justify but it’s very interesting, not sure if being first generation owner will be good since second generation and so on are always superior. Good video, great mission
Do you call yourself greenboy or is the extruder called greenboy? What does it mean? I guess it's not about climate, and not a toy for a little boy? ;) I like to see the extruder become available, and you are doing good work. Good luck with producing and selling the kits!
400 dollars!? My printer costs half that and it's almost the average wage in my country. I wish I could afford it. As soon as I get the money I'm buying
You have to understand that the next alternative would be 800 dollars, so it is half the price of what you would normally have to pay for a pellet extruder 🙂
Hi, yes, it also works with the Prusa mk4(s). Have not announced it publicly yet, but soon there is coming a new big update on the ongoing progress and there I will also announce that adapters for all the Prusa printer are created. 🙂
@@mmmuck Sounds great! 🙂Should you have any other question, feel free to contact me through email, where I can give you a more in-depth answer. Actually Most parts for the extruder are already produced, and I am just waiting for the last parts, which will arrive next week and approximately shipping will start mid-November of the "production ready edition"
1) There will be plenty available & 3D printable Adapter mounts for various 3D printers and a tutorial that will teach how you can create a custom adapter yourself without the need of prior technical CAD skills. 2) All 3D-printable files, including all adapters, will be freely accessible and downloadable on my website shortly before shipping begins, as I want to give them a final touch-up before release.
I would place my order right away if I see how well it works with chocolate. My only concern is melted chocolate getting melted in the hopper before entering the worm gear.
The pellet extruder was designed in a way so that the "barrel entry" stays cool so that material will not start to melt premature. There still will be a video about chocolate 3D printing, don't worry 🙁 I am just focused right now on getting a lot of things done before August
Where is a video showing the printer in action and with close ups of the results it delivers and with at least some numbers (layer height, print speed, model size)?
@@greenboy3d Thanks for the quick answer. But what about high resolution photos of the results? Looks like you are printing rather large objects. What about a normal sized 3DBenchy?
@@entmontage I might do high resolution photos in the near future, but for now my main focus is to produce the pellet extruders for the 464 people who pre-ordered...
@@greenboy3d and what about the capability to print normal sized 3dBenchies? Or is your extruder only for large objects as all the other pellet extruders on the market? Makes no sense to me to put it on a small printer like the Ender if you can't print small parts with a good print quality.
I dont think its compatible with my Snapmaker as it does not have direct connections for fans and heater but uses some more advanced connection based on some CAN bus I think. Cool project tho - its always nice to see 3d printing evolving. In my opinion it would be still better to do device that would accept and shred plastic on one part and produce filament string on other - no problems with compatibility also :) ... but this will probably make lot of hobbyists happy too :)
I used the Ender 3 so much to demonstrate that my Pellet Extruder works even on cheap, low-end 3D printers and still produces good results. If it works on an Ender 3 it will work on almost any 3D printers 🙂
There are many people in the Greenbody3D Discord Server that planning to modify their Vorons and Ratrigs with it. You are welcomed to join aswell here > discord.gg/UuFDbFj6FC
@@greenboy3d yeah, the working field; was mostly talking about you having to work a stressful late night job at UPS (who are the fork decided 4 to 8 a.m. would be good working hours anyway >.>), but jobs, and mostly managers (if not the co workers, as well as certain customers), just tend to suck in general -.-
Btw. I think you need more exposure. Did you already send your extruder to the usual suspects of 3d printing youtubers? This is how such products get reviewed. send them for free and get attention.
[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.

Anything planned for the bambu lab printers? @@greenboy3d
Hi Greenboy,
I have been exploring the possibilities of a pellet extruder and large format printing about 10 years ago. Back then i put a lot of effort and research in, so i like to share the hard work i put in back then as i did not print with pellets ever myself..
What my main conclusions were then:
1) The pellet extruder is a 100% needed tool for large format 3D printing. Printing a chair would be about 6 kg of material. Costing about 3 euro per kg = 18 euro for printing a chair. GREAT SOLUTION! Instead of 30 euro per kg. (prices then) = 180 euro for a chair. (TOO MUCH!)
Print a 6 kg mailbox for packages for 18€, sell em for 75 and you have a business.. If you print for 180 and want to sell for 400, that would be too expensive compared to other production methods.
2) A printer, about the size of a washing machine and slightly larger would be a nice size, because that is related to the size of the human body. Almost anything made from a cardoor to a lawnmower, sinks, microwave or table. The size is related to the human body.
About 85*85*85 is a nice size. Or for example 1*1*2 meter. The size of a door. But parts can also be connected, so the 85*85*85 is actually good.
3) This would also be great for making (large) molds for composites, concrete and more..
BUT:
1) it has to be 100% reliable. Not 99%. And if the plastic stays in too long, it will clog easily.
You need a clogging protection script. And a dumping basket just like the bamboo A1.
When material is longer in the hotend than say 20-30 seconds, it should start flushing.. Otherwise the material burns and clogs.....
Also at start up and cool down. This is really important. if it clogs once, it takes A DAY!!! to repair and the pellet extruder is financially totall loss..
Also take care about a superfast startup and cooling down time.
If it takes 10 minutes to heat up and 10 minutes to cool down, there will be material in for 20 minutes, the material starts to burn so 100% guaranteed clogging.
SOLUTION:
A) POWER on the heater. use a lightweight, powerfull heater. Heat the barrel in 10 seconds instead of 10 minutes. Use a relais and 230 volts..
B) Use powerfull cooling after printing. Cool it down fast. If you want to keep the moving parts as light as possible, make a cooling down location on the printer, just like a material drop box, Put the nozzle in water, oil (non electric conductant) or cool with air and a powerfull fan pushing air at the righ spot.. Try cooling it down in 15 seconds.
C) There should be a flush material dump at the end of the printing cyclus.. So the printer heats up with fresh, un burned material.
D) start with large nozzles (not too small) so it flows easily.
E) Make it easy to take it apart.
2) Experiment with fibers in the material. That can produce about a two times higher strength to weight ratio in the product..
So way better product, lower printing costs, printing the same product/strenght twice as fast. And this can also be made in a kind of envirementally friendly way.
PLA can be made out of starch, bioplastic. Mix it with woodfibers and the product looks and feels like wood. Long fibers would wind around the extruder shaft, but 2? mm fibers could give strenght.. Try mixing 70% PLA, 15% flax short fibers? 15% sawdust and a spoon of arachide oid (boilingpoint at 300 degrees, printing at 210)
Arachide oid makes the sawdust stick to the pellest so it mixes well and it gives a little bit of flex in the material...
3) The system should be light. Heavy motors, heavy everything could give problems. Then you also need more heavy XY motors, more heavy stepper drivers, more heavy axis, so the entire systems starts flipping over if it becomes too heavy..
SOLUTION:
Make a weight strategy.. Put the pellet extruder (every month) on a digital kitchen weight scale and then start scraping every gram of.
Use carbon fiber parts, use aluminium instead of steel? Ise glue instead of bolts. Use a flexible drive shaft instead of a motor on the extruder, push cooling air through a super lightweight flexible hose/tube? and save 50 grams of the fan weight? Use a light stepper motor with a cooling rib instead of a more heavy motor. Very often lighter = cheaper = better. Using less material for the extruder makes the extruder more affordable.
I also suggest to use a thermal camera when developing. So you can see whats going on.
4) The heatbreak is important. The point between the hot some and cool zone should be well designed
5) The system should be silent. People run a large printer in an office, an attic, a room, a garage..
6) The auger you use is already way better than what i've seen in my life.. 10 years ago people were trying wood augers... A well designed auger is part of the solution. I think the barrel and auger metal should be higly polished so it has less chance to stick?
I think you're in the right direction of a solution.
7) The flow control is important. With filament and decent gears you can say 100 mm = 100mm but with an auger its harder to extrude excactly the right amount.
If it extrudes a lot the material temperture is slightly lower, if it extruded not so much, everything heats up a bit more...
My idea about this was to stabilize the temperture bu using a heated pellet hose.. The pellets go in at say 80-130 degrees. Pre heated..
Then 1) you can print faster! (allmost twice?? as fast) And the temperture is more stable in the hotend as the are no cold pellets going in.
With a more stable temperture, its easier to predict the output so it also stabilizes the output.
If the hotend has to bride 20 degrees - 210 = 190 degrees gap. With a 110 degrees pre heated hose it would only have to do a 100 degrees gap... And maybe doubles? the output of the extruder? Printing fast, what is a benefit if you want to print big things.
8) Find donations for the pre commercial stage... Connect to (local) industries.
- Ask bigrep to donate a free printer to use (lease) for 2 years. Then send it back or so..
- Consider kickstarter.com or so.
You can use AI to build a very quick website now, with lots of functionality.
Like crowdsourcing adapters.
Just saying.
I'm glad SOMEONE is finally doing this, it seems like such a no brainer but you're the first to give it serious effort.
There is a lot more to come. Time needs to pass and you will see what I mean🙂
Likely because 3d printing companies have good margins on their filament and don't want to lose a ton of money
I am not buying it for now becuse I don't really have the time to fit it among other projects but I am keeping a very attentive eye on your channel, thanks for what you're bringing to the community
I got the email on the day of the preorder, I impulse purchased it so fast, I kinda blushed a bit. I got dozens of bottles, a Re-PET machine, a filament joiner on the way, as soon as I have this, I'll be printing with 0.6mm nozzle and start printing my hydroponics kits. I hope your business becomes successful!
Thank you a lot of your preorder ❤ It means a lot to me! 🙂
great idea - bottles to hydroponics
I saw the community post a couple weeks ago about pre orders but didn't have the money. RUclips changed my subscription notifications from all to personalized, so I didn't see this video before today.
I'M STILL GONNA GET IT, who cares about a discount on the upfront price when I'll be able to crush water bottles into little pucks, dice those up to around 6mm, then just start printing?
That is exactly what I made it for. And bottles are not the only things you recycle... 🙂
Kristian, congrats for the project. Do you sell just the schematics and BOM of tha extruder?
Thank you for your kind words!
I sell the whole pellet extruder, not schematics or BOM.
Very soon there will be a "Wiki" on my main website, where people will be able to download more than 50 3d printable adapter for various 3D printers + the necessary 3d printed parts. And in addition to that there will be all kind of video tutorials about pellet 3d printing which will make the pellet 3d printing journey of many people much easier.🙂
Do you have more questions?
The value of this project is underrated. Thank you for your commitment! Very interested, especially adapting your parts for high temperature application. PEEK, PEKK pellets anyone? Game-changing.
Thanks a lot for your encouraging words! I appreciate it 🙂

Again, super excited and grateful for all the critical thought, R and D, and self-funding you've put yourself through to make this happen for all of us at home.
Congrats on the success of the preorder phase! Can't wait to finally get my hands on it!

Awesome! i'll definitely be getting one soon. Maybe add a side mount for a BLtouch for enders so they can still autolevel. Not to mention pretty much endless recyclability options at the fraction of the cost instead of buying a 5000$ filament extruder, and all the customization that you can put into the material. I'm so happy someone is actually stepping up and giving this technology a chance, and thank you so much for all of your hard work, and wish you the best :)
Excited to see where this goes long term! I do believe this is an endeavor worth pursuing, and if I had more liquid capital and time I'd back it in this early state. For me this is exciting, but not practical currently. The pellet extruder costs more than the printer I print with, and I print so relatively infrequently (mostly designing and making custom parts for around the home) that the cost savings over time would not be worth it. Upgrading my printer entirely would go a much longer way. I'm sure a lot of tinkerers will enjoy this, but I've always preferred putting my printer to work rather than mess around with it. Hopefully enough of these tinkerers will support your endeavors so that people like me can benefit from mass production in the future.
Thank you for your support ❤
Very interesting project. While it is not as cheap as I would have hoped, the quality it much better that the other options that are 1.5 to 2x more expensive.
depends on your filament pricing, locally i can get 1kg for 13 euro but i cant for the life of me find PLA pellets anywhere locally, it would in theory recoup the cost in a year or so of printing but availability is a concern. On top of that the project as a whole looks a tiny bit sketchy and there have been countless failed startups/ failed promises/ inventory and shipping problems and such, i'd be better to wait for proven results.
We are colleagues in UPS! Funny to know this 😂🤝🏻👍🏻😎
I'm so excited to get mine! I can't wait!!
Thank you for your pre-order! It means a lot to me ❤
Love this! Especially for recycling your own filament this would be such a cool and sustainable method!
I’ll definitely keep an eye on this and all the best to you and the project!
Finally convinced myself to support your effort by ordering your extruder! It is very exciting to be a part of that future!
I must find a printer to dedicate that build to though, they all are calibrated so well...tough call.
Keep up the good work! More 3dp vlogers should talk about this project!
I like the Thing and love the story of dedication and hard work. Well done and good luck!
Thank you for your supportive words :)
I really hope this project succeeds for you!! While I definitely think I'd keep a standard FDM printer for detailed printing like for Props, and other items, I would be interested in picking one of these up down the road for recycling materials.
I just barely got into 3d printing, getting my own printer for the first time, but I'll definitely be keeping an eye on this project!
edit:
Out of curiosity, could a pellet extruder in theory be turned into a filament making tool? I've seen people turn extruders into tools to make multi-color filament before, granted that wasn't easy from what I saw.
Wishing you the best! Just dont sell out like the SLS printing guys did a few weeks ago!
I'm not at a point where I can make use of a pellet extruder but I enthusiastically support your project.
Thank you 🙂
Any wishes for future videos?
Definitely happy for you and happy for the community. I do not think this will change the market to move away from standard filament because I know I won’t but there is now options. I plan do mostly filament printers and then work your pellet extruder for the Neptune Max 4. I will use the Neptune for bigger prints with extruder and see what magic happens. Very excited when I can afford the extruder. Really good work my man!
Yeah , i feel that for smaller printers filament will still be the way to go , but larger printers will benefit of the pellet extruder the most , since it will allow fast , big and cheap prints
@@ulforcemegamon3094 Smaller printers would definitely be the way to go. However, if you can dial in the new pellet extruder with a big printer, definitely would be something to see and save us a ton of money on bigger prints 😃
Nice to see you've been able to move forward with this extruder.
Thanks for the appriciation :)

Have you thought about making the same thing, but that extrudes out of a 1.75mm nozzle to extrude normal filament?
It is not something I have thought about, it is more something that I have planned to develop in the near future...
Would you want such a thing? 🙂
@@greenboy3d definitely. I’ve been looking for something small/ contained that can just make spools of filament from pellets, but hopefully not break the bank
@@greenboy3d ya please look into it something similar to pet bottle extruders, would be helpful and much more budget friendly :)(pellets to fillament)
@@incridablekarthi228 what price would you consider budget friendly for filament maker from pellets?
I can't wait to get one of these. I don't expect it to work with my bambu labs x1c though. Thankfully I have an old prusa mk3 somewhere.....
i do like the extruder a lot. However, I must say I am holding off on the purchase till a later point. As in my case, I am more worried about the extrusion consistency with the produced print. If I have a idex printer, I might consider buying it as a infill only extrude.
Using a pellet extruder for infill and a filament extruder for the rest sounds genius tbh , use the pellet extruder for infill as detail doesn't matter there and use filament for the exterior of the print where detail matters more
The Legend is back
Was never gone 🙂was just preparing everything like the website, organizing the production and much more "behind the scence" stuff to get everything rolling 🙂
Well done! Looks really peomising
Thanks :)
You're doing great man! Keep it up!
thanks 🙂
What You do is super impressive regardless of the outcome. Congrats Really :)
Thanks 🙂
Is it an open source project of your own or do you keep it close source and only sells the kit ?
Have you tried filtering/sorting your pellets by size with meshes? This should improve print quality and strength
If you shred for example your old 3d prints into granules, then this method of using meshes works very well as I showed it in this video: ruclips.net/video/eWgzi4a1bJo/видео.html
However, normal pellets are generally speaking about the same size but have due to their shape from certain angles different sizes which make proper filter almost impossible...
I really hope it's a success for you
It is and thanks for your wishes, however there is still a lot of work to do... 🙂

I'm very interested. However, I am mostly interested in large scale 3d printing right now, volumes up to a cubic meter. So, I wonder: What size nozzle can you put in the extruder and what maximum amounts per seconds may I print with it?

yeah we rly need a video on where and how to buy pellets. Because this is a great project but from a bit of google most pellets actually cost MORE than filament which destroys the whole purpose
Hi :)
First of all I want to apologize for the late reply. 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
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 guess you can do another project like filament extruder machine, which make our own filament directly from pellet.
Congrats !
I think there is a patent for this from D. Casey Kerrigan. How did you get around the patent? I don't know how this stuff works.
His patent is abandoned
If she took a patent on this idea she took a patent on stuff that was already published in Sweden in 2015. Looking through her patent her design looks an awful a lot like the prototype I made for one of the projects :D
@greenboy3d is your pellet extruder usable for bambu lab? Easily? Pls work on thatttt and I can review it hehe
I'm about to buy a Bambulabs printer for the multicolor capability. Could I install this on my Ender 3 V2, grind up the poop from the Bambulabs (with a coffee grinder?) and use the Ender for stuff where the color doesn't matter?
Do the Creality Ender 3 specs match the Ender 3 Neo Max, in terms of the adapter? New to all this, and nothing ever talks about the Neo, just the 3
There is an adapter for the Ender 3 Neo and Ender 3 Neo max already made. I have not yet updated this on the "available adapters list" in the FAQ on my website, but it was already created.
So you don't have to worry, there is an adapter for your 3d printer, and it can soon be downloaded on my website once I have built the basic WIKI... 🙂
Should you have any other questions, feel free to ask.
Can’t wait! Great job!
Thank you for your support 🙂
To be honest, this costs more than my printer did, but I'm pretty sure the added utility makes it worthwhile. I think this is the greatest advance in rapid prototype printing since the self-leveling bed. Your efforts are appreciated.
I agree the price point is a little high, though likely worth it. I’m sure this will spark a whole new era of printing.
You should wait untill it becomes cheaper.
i really wish i could support you at this time! hopefully next year i can make a profit form my printers, and find a shredder to recycle my failed prints.
You should really watch that Golden Boy anime, if you ever get the time! Your dedication is legendary :)
Ein Thema was für mich wichtig wäre zu klären ist das trocknen vom Granulat.
In einer Heißluftfritteuse oder Ofen ?

what do you reccomend to grind the filament? i've just destroyed my coffee grinder trying that
I think what you’re doing is awesome. I’m just not the target audience. I do t even have a 3d printer but I’m looking at the A1 mini. I’m not sure if that even could take the pellet hopper swap.
In any case, 3D printing isn’t a hobby for me. I’m a woodworker primarily. I just want some custom parts that could be printed. But in order to break even with a $400 pellet extender I would have to go through the equivalent of $500 in filament if pellets are 5x cheaper.
That’s likely more than a lifetime supply of plastic for me, probably way more. If I ever do get into this as a serious hobby and would burn through that much material it would make sense to go pellet.
Of course the biggest game would be recycling the plastic infinitely, but to my knowledge most plastic doesn’t work like that? How many time can you recycle your printer poop or old parts?
Thanks for your kind words 🙂
Depending on the plastic you are using you can recycle it 3 to 7 times.
I assume retractions (or the equivalent) is the weak point?
Damn I really want to bite the bullet and buy this I don’t have the printer but I want to garante that I can also get this.. it’s on the pricy side especially since I’ve never had a 3D printer before and don’t know if I’ll use it enough to justify the price.. if I get it I’ll probably be using an ankermake printer but I also do care about resolution for the parts I’ll be printing and don’t know if spending hours sanding it down would be worth it since it may discourage me from using it more. Have you tried printing with resolution as the main goal instead of just it being cheaper? I know FDM printers can only get so clear but the differences in the resolution from what I’ve seen on normal filaments and the ones I’ve seen in your videos (I’ve watched all) is drastic enough for small sensitive parts to not work as intended, but the fact that the pellets mean it’s actually going to be available for me to buy without a hassle/less of a hassle is such a positive point since it’ll not just be cheaper without shipping but even with shipping costs it’s still a huge difference, besides if I have to print a mount for the new head, I as a beginner don’t have any filament to even to use in order to print that and adding it will be a big cost, since I’ll have to take out like 45$ off of the printers budget for that roll (25$ for the roll and around 20$ for shipping), sometimes the printer comes with a small spool but that’s to test print so it’s barley enough for that test print let alone having an adapter printed, and if that print fails since I’m a beginner I’m out of luck and ill have to find someone who can print it or get a full spool. The initial cost is huge now but I know it’ll go down eventually, on the other hand the new iterations/versions of this extruder will definitely improve upon its mistakes till it’s flawless but that means version 1 is going to be something aimed at the enthusiast market where they know how to tinker and adjust things without having to need someone to hold their hand with instructions.. I’m unsure when or if a second version will come out (hopefully it will) but everyone who buys a first generation of a new product will run into the first generation problems, it’s inevitable, and the second is always better, at the same time I don’t know if I want to wait another year as I’ve been looking at 3d printers for ages and at many points I was a couple steps away from owning one, one time a shop imported a couple ankermakes and posted on their instagram at like 10 am, my dad sent the post to me but I didn’t check it till 7pm, the moment I saw I called them and reserved one (they said only one left) I went to the shop driving since I didn’t want to wait for the delivery (second day since it was at night) and didn’t know if someone else will come pick it up, the moment I got there he said it’s gone and he told us to contact them later to know when they’re gonna get more.. I was so pissed off this was the easiest and closest way I could’ve owned one, it was sold for cheaper than online too, WITHOUT THE SHIPPING PRICE, couple days go by and turns out they didn’t sell them, they were confiscated, I emailed Anker asking for the supplier contact info, I was given a number, messaged them, he gave my my regional number and I gave them a call. The guy said they were threatened and they were told they’re gonna shut down their business if they import without permission again, I mean it did get into the country so how is it their problem? The website that states the illegal list of products doesn’t say anything about 3d printers, the HS code is on the allowed list, it’s confusing to say the least but it’s in such a gray area that if you’re gonna being one in you have to be dedicated and it might just get confiscated then you’re out of luck and money, unless they return it. I called customs, the criminal information directory, called the department of interior, and ended up with a number that never picked up except for a very specific timing on 4 days of the week, after a week they picked up and I asked if I can order he said yes and when it comes it’s gonna take a while for them to call me and interview me then I’ll have to sign papers saying it’s for personal use and can’t be used for business purposes, unless I register the printer under a CR, which is stupid since I could have it personal but also print for others without needing a CR because opening a CR means I need a location, need to pay, and my name along with the address will be on the public registry just to own a printer that I can print for others and get paid for that, then pay yearly to keep the CR active, or sign it as personal and if I print for others it’ll be for friends and no payment, which is unfortunate since you can make some money out of it since it costs so much upfront and longer (filament). I asked if I could go through the process first so I can guarantee that h have the clearance before buying it so I don’t lose money unnecessarily but he said I can’t do that, he did say if I ordered it then it’ll hopefully be an easy path forward and it’ll be hassle free but when I asked if that’s guaranteed he said nothings for certain but hopefully it’ll be. Confusing mess. If I got to the shop earlier, had I seen the post before the ministry of interior saw it, I would’ve had the printer, they would’ve probably come to my house to confiscate it or make me sign papers but if they didn’t id have the printer with 0 hassle and 0 shipping fees. The shop didn’t have filament, they never sold 3d printers, they sell mobile devices and accessories so they sold anker stuff, hence why they brought it, they deleted all the instagram posts about it and every time I asked them about it (before I figured out what happened) they’d act like in crazy and they never brought or had it, first couple times they said they don’t know when they’re getting more, then they said they’re never getting it, then they started acting like it never happened. People on Reddit say you just buy it and have to wait for customs to do their things, do an interview and sign papers then if you’re cleared you get it if not no clue since no one who wasn’t cleared said anything. It’s sad, but they all said importing filament is not a problem since you can just buy it and it’ll come. I remember asking aramex (or dhl I don’t remember) if they get 3d printers delivered to here and the guy said yes they get like 5 a week (or month don’t remember). So I’m unsure why it’s so tedious and such a black area, 0 guidelines and you just shoot in the dark, been thinking of getting a printer for over 4 years and trying to find a way for about 2, obviously if I just buy one I think it’ll get through which I was close to doing multiple times but the problem is if I get it and can’t get filament for cheap (without it being completely garbage and end up breaking something or wearing some part out that I’ll have to wait for a replacement of) then it’s just going to be a paper weight. Lots of people buy a ender or something cheap and established as a starter printer since they can dip their legs in the water and see if it’s a thing they want to be doing, if I’m gonna try it I’ll have to dive in head first since otherwise I’m gonna have to go through all the process again (and considering shipping 200$ for a printer is not cheap, since I’m paying more or the same just to ship it, and id rather have 1 great printer than 2 decent ones/ones that I’ll have to repair myself since they’re more “DIY” and if something breaks you have to fix by troubleshooting everything, instead of just warranty or repair by a less janky method such as more seamless process since the ender variant is pretty old with slower technology (speed wise compared to new ones). Bambu labs will be very expensive, ankermake I’ll be spending about 270 BHD on it (excluding shipping) (this is the price the store was selling it at). I even asked the local anker dealer if I bought one and needed repair if they can help they said they can’t and I’ll have to ship it to Dubai since the main supplier is there for the Middle East. I’m in Bahrain btw, not sure what this comment was it went from something to another but I think I got my point across.
TLDR getting printer is hard, price for extruder isn’t cheap for a complete beginner, not sure if I will spend enough time to justify but it’s very interesting, not sure if being first generation owner will be good since second generation and so on are always superior. Good video, great mission
Do you call yourself greenboy or is the extruder called greenboy? What does it mean? I guess it's not about climate, and not a toy for a little boy? ;)
I like to see the extruder become available, and you are doing good work. Good luck with producing and selling the kits!
What's the flow rate?
125 to 200 grams per hour
400 dollars!? My printer costs half that and it's almost the average wage in my country. I wish I could afford it. As soon as I get the money I'm buying
You have to understand that the next alternative would be 800 dollars, so it is half the price of what you would normally have to pay for a pellet extruder 🙂
Can i install it on my p1p ?
Ok ok, you got me. I'm in. I'm actually most concerned with gcode settings and the software end of setup more than anything.
Why not make filament form the pellets?
I hope you succeed beyond your imagination!
I'm curious if this works with the prusa mk4(s)?
Hi, yes, it also works with the Prusa mk4(s). Have not announced it publicly yet, but soon there is coming a new big update on the ongoing progress and there I will also announce that adapters for all the Prusa printer are created. 🙂
@@greenboy3d amazing I'm using this at a college and will likely buy the production ready edition. I'm very excited for you!
@@mmmuck Sounds great! 🙂Should you have any other question, feel free to contact me through email, where I can give you a more in-depth answer.
Actually Most parts for the extruder are already produced, and I am just waiting for the last parts, which will arrive next week and approximately shipping will start mid-November of the "production ready edition"
Are you going to release the files so we could print it ourselves?
1) There will be plenty available & 3D printable Adapter mounts for various 3D printers and a tutorial that will teach how you can create a custom adapter yourself without the need of prior technical CAD skills.
2) All 3D-printable files, including all adapters, will be freely accessible and downloadable on my website shortly before shipping begins, as I want to give them a final touch-up before release.
Keeping a close eye on this and I have boxes of failed prints that need to be recycled
Good to here 🙂
I would like to see sovol sv08 extruder adapters
I would place my order right away if I see how well it works with chocolate. My only concern is melted chocolate getting melted in the hopper before entering the worm gear.
The pellet extruder was designed in a way so that the "barrel entry" stays cool so that material will not start to melt premature.
There still will be a video about chocolate 3D printing, don't worry 🙁
I am just focused right now on getting a lot of things done before August
Fyi, Hisun PLA 110 should cost around 3-4$/kg for 25kg bag.
Letz go, meine cr 30 kann nicht warten
Das freut mich zu hören! 🙂
Where is a video showing the printer in action and with close ups of the results it delivers and with at least some numbers (layer height, print speed, model size)?
Almost in any other video on my RUclips channel or on my website, greenboy3d.de
@@greenboy3d Thanks for the quick answer. But what about high resolution photos of the results? Looks like you are printing rather large objects. What about a normal sized 3DBenchy?
@@entmontage I might do high resolution photos in the near future, but for now my main focus is to produce the pellet extruders for the 464 people who pre-ordered...
@@greenboy3d and what about the capability to print normal sized 3dBenchies? Or is your extruder only for large objects as all the other pellet extruders on the market? Makes no sense to me to put it on a small printer like the Ender if you can't print small parts with a good print quality.
Wish I could afford one. Just had yo buy a creality heated box because where I live is really humid
This is awesome a little pricy but would love to use it in more mainstream printers
I dont think its compatible with my Snapmaker as it does not have direct connections for fans and heater but uses some more advanced connection based on some CAN bus I think. Cool project tho - its always nice to see 3d printing evolving. In my opinion it would be still better to do device that would accept and shred plastic on one part and produce filament string on other - no problems with compatibility also :) ... but this will probably make lot of hobbyists happy too :)
I hope this becomes standard
I will do my best to ensure that 🙂
is there a reason why the top of your video has a constantly flickering gradient? it's so distracting on my OLED
Going to be fixed in the next video
@@greenboy3d thank you!!
can the extruder not print fast? seems like you only advertise it with the ender 3. seems like speed is going to be a trade off?
I used the Ender 3 so much to demonstrate that my Pellet Extruder works even on cheap, low-end 3D printers and still produces good results. If it works on an Ender 3 it will work on almost any 3D printers 🙂
Thicker extrusion, slower print moves. It's still going to be fast
Its available??????!!!!
yes! Greenboy Pellet Extruder V1 is now available
Noooo why do I only discover this now :(
Very good video!
Neat but I couldn't consider something like that unless it were under $100 as a similar extruder is available from china for around $60-90
There is no similar extruder available for $60-90. What ever it seems to be - it is not a good pellet extruder... 🙂
I want the second or third generation of this extruder. I do not have the money right now and I would like for others to sort out the kinks.
*Sadly most people wil not buy until they see the reviews.*
Has anyone tried modifying their voron 2.4 to support this?
There are many people in the Greenbody3D Discord Server that planning to modify their Vorons and Ratrigs with it.
You are welcomed to join aswell here > discord.gg/UuFDbFj6FC
@ thank you! Just joined
I was interested but no mention at all about bambulab printers :(
check his website about the adaptors, aslong as its an fdm printer you will be able to get an adaptor either now or later or diy one.
You should try to open a Patreon in the future.
There is actually a Patreon, which can be found in the linktree on the channel page 🙂
i want a fully assembled printer like this
has anyone even heard from greenboy3d since early September about progress?
Hi Dennis I think, I answered your email recently 🙂
Sorry if you had any concerns, I simply was very busy with the background work
yeah ramping up actual production is a thing
w extruder
what?
@@greenboy3d”w” as in win, he’s saying it’s a good extruder
Demo please!
I just hope you do not get bought up ... Like those guys
Don't we just love working jobs that suck.. not like people could make them not suck or anything -.-
Is there a problem?
@@greenboy3d yeah, the working field; was mostly talking about you having to work a stressful late night job at UPS (who are the fork decided 4 to 8 a.m. would be good working hours anyway >.>), but jobs, and mostly managers (if not the co workers, as well as certain customers), just tend to suck in general -.-
Btw. I think you need more exposure. Did you already send your extruder to the usual suspects of 3d printing youtubers? This is how such products get reviewed. send them for free and get attention.
I will send some units in the near future to some RUclipsrs
