​This is listed in one of the challenging projects I have ever made. During my normal build I sometimes failed in achieving the final result but in the end accomplished that but this is the case in which I don't know I failed dozens of times and I think this is what happens when someone starts inventing new. I have been working on this project for the past one and half months and in the start I thought it would not be a difficult project but it made my life hell during this period. I don't even remember exactly how many times I failed but I don't want to get beat up by those obstacles. Now the origin of this project starts back one year ago when I built 3 in 1 cnc. At that time my brother said what if we made an extruder which was capable of using waste plastic and here after one year I am able to make a pellet extruder. Now I don't have enough time to play much with this tool because I am busy supervising construction work but in the upcoming week there are definitely some videos coming out onto the channel page, so don't forget to watch them. Another main reason to build this project is to directly use the old failed printed parts to reuse them. Now one thing I have to mention is that this is definitely a difficult project to make. I also wanted to use the waste plastic bottles for my 3d prints to make planters and other useful items. One thing I definitely wanted to mention is that if you have the right tools like a lathe and milling machine the execution will go a lot smoother and easier. During this build I always find that lathe would be the essential machine to make these kinds of projects. There are so many phases where I can utilise lathe to avoid multiple parts construction and make them with a one single body. In that way I think I am able to reduce the weight of the extruder at some extent. Now as far as nozzle is concerned I didn't have right tools to make a nozzle that's why the size of the hole I able to drill is 1.5 mm which is definitely thick but if you wanted to make planters and other decorative items in which layer height doesn't matter it won't be a big issue. At first I made a design which I also machined onto a piece of brass but in the end I have to scrap it and start over from the zero. The main reason for the failure is that I underestimated the pallets and amount of force they required to extrude. This instructables didn't have any design because it didn't go the way I wanted to at first and then I just went without any design and failed a few more times and then finally it's done. The main motive is also to tell you the points you need to consider while designing a pallet extruder for your 3d printer. Now I definitely did a couple of tests and found that with the material having smaller granule size like 1.5-2 mm size there would be no problem in attaining the speed of 50 mm/sec but with the thicker material like 3-4 mm I can't able to go more than 24 mm/sec. In the vase mode with the same bigger material I am able to manage up to a speed of 30 mm/sec. Now definitely many factors still take place while extrusion like material temp, temperature of hotend, motor torque etc. But what I found is that you can't achieve the fast speed without adding much weight. Now if I increase the hotend length so that material starts much longer in the heater block and the Design is also a converging type to feed the material then it will definitely improve a bit more. So overall said all the failure which I faced in building this pallet extruder I am going to share that with you. Now if I start making a video over this project including the failure then without a doubt it will definitely cross more than an hour and it also increases the editing time. So I put all that information in these instructables so that if anyone is interested in building one there are many points he/she needs to consider. The overall weight of this extruder is 1860 gm. It's definitely on the heavier side but my 3 in 1 cnc didn't face any issue of weight during the prints. I knew there are many experts sitting over here so I strongly urge you to share your feedback and tips regarding this extruder. Now without further wasting anymore time let's build this bad boy.

Superb work, this is an inspiration to every maker :) Loved the screw in particular

[@ambroscustom]

Thanks for the words brother, yeah I compare the screw with the wood auger bit and found that the shape helps to push the material more compare to wood auger, so made my own and it's working flawless. Still in a testing phase and hopefully in upcoming weeks showcase some fine prints with this.

[@benjamindavoult3654]

dirty workshop, great music, awesome machine, the way it should be. btw this kind of printer will probably be needed on Mars or the Moon. I think you can improve it relatively easily with a cooling fan, and also a system that lift the bloc motor-coupler-screw to make a retraction and avoid stringing.

[@ambroscustom]

Hahahaha.... thank mate. Yeah currently been playing with the settings definitely cooling required, stringing actually caused by the wrong filament dia in the cura, now it reduces to some extent but yeah still present. Hopefully in upcomming video able to completely reduce it.

[@silviomejia905]

Excelente buen trabajo Lo felicito

[@yazdanvakili7057]

everything was great, but the screw you made with those kind of tools, man it's craftsmanship

[@ambroscustom]

Thanks for the words pal, you should watch mark 2 which I would say a much better version than this one. But still need some refinement.

[@homemadetools]

Great build. We posted this video in our homemade tools forum this week :)

[@ambroscustom]

Thanks mate..👍

[@diegogran2858]

Looks great! Seems like all it needs is a lot of cooling to reach better quality prints.

[@ambroscustom]

Thanks, Yeah, there is smoke comming out during prints, I think it required hell lot of cooling.

[@chetan.gondaliya]

Awesome bhai... I m amazed like a child watching a Magic show...!✌💪🙏

[@ambroscustom]

Thanks brother:)

[@sambarjunk]

Great effort.

太厉害了🤙🤙🤙

[@asifrather5206]

Superb ❤️👍

[@ambroscustom]

Thanks :)

[@onlineshaman]

This is *crazy*... but I love crazy projects! :-D My main sorrow is that palletscontain a great quantity of glue, cleaning that printing head after a couple of prints will be a major problem! :-/

[@ambroscustom]

Thanks for the words, I didn't knew about that glue but yeah I noticed that garbage stuck around that heater block.

[@MrGoulien]

Amazing work! Very impressive!

[@ambroscustom]

Thanks mate:)

[@thomashverring9484]

That was impressive! (I just wish there weren't any music. I'd much rather listen to the work!)

[@ambroscustom]

Thanks mate.......music gives a time duration to finish the video, otherwise video goes alot longer.

[@RadekSzabla]

hello my friend , can you build one for me - i want pellet extruder for my shredded plastic . i like your extruder - i can buy the screw , motor and coupler myself you do the rest.

[@rudrapanktimanikantha5174]

Please let me know how to reach you. I would like to work on a screw type extruder much as you do. I need your help and direction. Thank you, Sir

[@RandomMiscShit]

Found this as I plan to do this exact thing. What was the motor you used? Can you provide a link for it?

[@ambroscustom]

Dear rather than buying a motor you need to buy nema 17 gearbox. And make sure you buy gearbox with metal gears. Usually those gearbox which are black in colour are often come with metal gears. You can find them on ebay or AliExpress. www.ebay.com/itm/265440448917?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=O-BKoyVeTNi&sssrc=2349624&ssuid=&var=&widget_ver=artemis&media=COPY

[@thejusprakash7164]

Sir can you please do a video on testing & review of abrasive cutting wheel available in our market

[@ambroscustom]

We surely will upload soon..

[@MrSlehofer]

could it work with finely crushed dried waste plastic too? HDPE or PET from plastic bottles or ABS from various waste electronics/cars, basically directly recycling plastic waste into 3D prints

[@ambroscustom]

I think it will going to work becasue i tested with waste 3d prints, but issue i am facing with them it that they contain some amount of moisture due to washing them with water as they are alot more dusty and becasue of that poping sound came up and vapours starts to form and got traped in screw area. In my upcoming video i am going to made some prints with those hdpe bottles and polyethylene so stay tuned.

[@MrSlehofer]

@@ambroscustom yes moisture is a likely issue, that why i specified "dried" waste plastic in my comment, putting them in the oven at a temperature sligthly above the boiling point of water for a few hours should be sufficient looking forward to your video!

[@nagato8152]

Quick question please do reply from where do you source you raw material ie copper aluminum steel pipes and rods in india

[@ambroscustom]

I purchase all materials locally. I lived in ludhiana which is an industrial hub. All industrial materials available in any form you required.

[@Latrocinium086]

Lol a Mexican flag, but Irish music….lol…Bo I’m Irish and probably darker than you 🤣🤣🤣 but some excellent work good sir!

[@ambroscustom]

Appreciate your words brother. That is Indian flag.

[@Latrocinium086]

@@ambroscustom apologies friend. My eyes are getting old for the small stuff. Thanks for your understanding. Still greatly enjoyed the content. Thanks for sharing.
