I think this is amazing. As a 3d printing company this would be a great benefit to anyone doing printing or making. It's important we start to reduce the plastic waste. And now with the vast filament selection. And mainly useless trinkets printed that are thrown away. We can now focus on recycling all of this
This is cool, i work on large extrusion machines making vinyl window parts, its really amazing seeing this on a smaller scale, it kinda reminds me of our capstock extruders
You guys are doing such a great job here, I have shared this channel as much as I can and appealing to donate to the cause. Good luck with your efforts.
congratulations, that machine is awesome, here in Colombia i worked in a company where posts and boards are made from recycled plastic, the machines retain the same concept as yours. molding is done by extrusion and then cooling by immersion in water. greetings.
As an extruder manufacturer， I must say it's really nice, maybe i will show this to our designer and give them some inspiration and make a mini cute extruder😄
Hello, dear friend. This is Lindsay from JAIHO Min China. Are you interested in recycling machine? We can help you, dear. My whatsapp :+8618868089679 or send me email service doc@jaihogroup.com.cn
one thing i've noticed missing from the list of machines, and making recycled filament being mentioned, for a greater control on size, and compactness between extruder and spooling device, A water bath is handy. cools the filament so it locks in the size, it's less likely to stretch or deform after that.
Hola soy Efrain, (no se si este comentario llegara al autor del video, pero espero que si) tengo 16 años, estudio electromecanica y me parecio un buen proyecto de escuela, pero fuera de lo escolar e decidido hacer todas las maquinas presentadas en la pagina, creo que es una gran idea para cambiar el mundo. desde pequeños avances en mi ciudad se pueden hacer grandes cosas. Un gran saludo desde Queretaro Mexico (algunos amigos esperan la traduccion del video :D) Gracias por compartir estas grandes ideas...
Que onda. Si quieres yo te ayudo, ya he estado haciendo mi máquina, espero terminarla en esta semana. También puedes utilizar el traductor automático de google y para traducir el video ponle en cc y seccionas subtítulos en español
Even if I weren't as bad as I am with mechanics, I can't afford this amount of work and neither can pay for all the tools you used. But, I would like to have a machine like this at home. I'm trying to go zero waste but there's a lot of stuff at home made of plastic that I want to turn into something useful. How could I do it to have someone doing it for me? Who should I contact? By the way you are saving the planet and is so inspiring to have people like you on this planet
Very informative and entertaining video Dave, on the subject of modifying and hacking this machine's orientation is very similar to horazontal injection molding machines, if clamping force and an assembly for the mold holder/ part ejecter can be drafted this could turn into an automated or semi automatic injection molding machine instead of the labor intensive hand operated one.
Hey, I thought about building one of these machineries, because I like the Idea, but isn`t it almost impossible to clean this mechanism, because of the molten plastik everywhere ? May you publish a video, showing a cleaning-process please ? Thanks for Answers in advance
if everybody decided tor recycle plastic like that instead of just throwing it out there wouldnt be any in the ocean people need to stop looking at plastic like its trash but rather like a materials that can be recycled indefinitely to make all sorts of stuff like tables car parts tools etc
Hello ! I'm almost done building everything I just have a problem with wiring everything I'm very bad at this and tried to find at the forum but couldn't help would be very appreciated Thank you for this amazing idea !
In joy the video thanks for shearing. I have a welding tip grinding where you are going to weld will make the weld stick better. Look better. And you won't have as much build up. Less inclusion in welds. Anyway just my 2 cents.
Amigo soy estudiante de universidad y me gusta mucho este proyecto pero los planos no estan en la pagina, ¿tendras un link donde pueda descargar toda la información, planos y diagramas para hacer la mía ??, gracias.
Really nice video, i want to build something like this and I was wondering if you have any problems with air bubbles trapped in the material and with the fumes that come out from the melting process
Excellent video! I've been struggling with something similar for some time. What would you estimate the maximum diameter of extruded material would be?
From your developments, i can build all-in-one machine. Shredder -> extruder -> printer. I threw plastic in to the case and after 32 hours the printer do anything that i was needed at home... great scott! :D i hope in 2019 you are already do it.
Hi Dave, first of all great video series and work! second I have a question: when I melt down food grade plastics such as HDPE or PP and reform it into watever new item is it still food grade?
What University is this? Certainly this is not your shop & not your equipment...indeed resourceful individuals can find ways of achieving this result, & perhaps even better, but this set up is IDEAL!!! But great job my friend, I DO enjoy the video, the basic info etc. & your sense of humour.
Hola, lo felicito por varios aspectos, uno de ellos es el de la preocupación por el planeta y la concientización de los seres humanos con nuestros desechos plásticos. Lo otro por sus excelentes videos y la enseñanza a partir del reciclaje y la realización de máquinas para la manufactura de los plásticos.Un gran saludo desde Colombia... Hello, I congratulate you on several aspects, one of them is the concern for the planet and awareness of human beings with our plastic waste. The other for its excellent teaching videos and from the repair and maintenance of machines for the manufacture of plastics.A big hello from Colombia ...
Machine looks to the level I can build one with my tools. Only doubt is, I see in your site maximum it is supposed to run for 4h/day. What prevents it to be used for longer runs? I would want 8-12 hours runs at least, but pro-makine is a bit overkill for the purpose. What should be improved in this machine to have at least these run times?
Thanks man! You are so smooth getting it done, wonder if I can do them as easily as u did. I need something slightly bigger. I need one that can make a 2'' elbow. Can you do it? I hoping to pay for both the extruder and mold. Please let me know what you think.
Great video...definitely food for thought...good job well done...I would love to have a go at this...might need to develop some new skills along the way and find some work arounds but this looks doable...
How about precision and repeatability of produced filament? Can this machine be used to produce perfectly round filament suitable for a 3D printer (1.75 or 3 mm with 2% tolerance)?
I think you could do that, but you need to enable stable positioning of the extruded filament at least to the distance from the nozzle where it has solidified. You cuold do that by winding the filament at a distance from the nozzle. This can be done with a motor operated mandrel. However I can guess this is not too simple because the winding needs to be done at the same speed of the filament extrusion, and as the filement winds, the mandrel rotation needs to be decreased accordingly. You would need to control motor speed electronically. I also think vertical extrusion would be better because in the horizontal conformation, the circular section of the fused filament would tend to flatten because of the gravity. In vertical extrusion you won't have this effect.
Hi, I'm from Argentina. I congratulate you on the project. I would like to know how many hours it takes to extrude a kilo of material for both filament and wood. I thank you and I hope to get more in touch with you soon.
Good afternoon, I really liked the project, I just wanted to know how to calibrate the worm with the drum or tube so that the worm does not pink with the drum?
How about open space machines? I am very intrested in these projects and will build machines 2018. Would love to see 'recycling stations' around the globe, where people can bring their plastic and walk off with some crafted things! Anyone up for teamwork near Bochum?
Yes, in USA, a 1/2" variable speed drill is good enough, eh ?- - just make a simple jig on the trigger using a lock nut and bolt, so you can turn the blot into the trigger to up the RPM's, lock the bolt in place with locknut so it does not vibrate off
Would not work. We need a slow speed motor is not really true. We need motor with high torque. How to get more torque? For examle, reduction gearing. Reduction gear is makes the motor slower and gives more torque. Its like your gear shifter vs gas pedal on your car. You don't shift back on uphill because you want to go slow, but because your car can't sustain the high speed under high load, just like your electric motor.
¡Hola! Una duda. ¿De cuánto voltaje son las resistencias y dónde las puedo conseguir más económicas? Al igual del motor,¿de cuánto voltaje es y dónde puedo conseguir uno semi-usado más económico?
Auger bit is cool but i guess it doesn't hav the ability to compress like a conventional extruder screw does so who should i contact if want to get made a real extrusion screw of normal size ? cnc milling or cnc lathe or normal lathe will do the trick..? and how much it would probably cost.?
Alpha Nerd this is too slow. It is for extruding filament. Precious Plastic got another machine for injection molding. It's even easier to built...the thing nit so easy are the molds. larger molds are even more complicated.
Alpha Nerd with an extrusion molder you need a higher capacity to continuously melt a given amount of material while keeping the injection rate high. How big a part are you trying to mold? Injection molding tools are rather sofisticated including cooling and heating For bigger parts like Bobby cars (HDPE) other techniques are used. they are made from hoses and blown up in the tool.
I built one myself and it works great! However, I am using a DC motor that gets really hot after 3 minutes of use. I know it will over heat if I keep at it. Does anyone know what motor specs I should be using? Several people below have mentioned high torque, but no one has mentioned the actual value or the operating rpm. Also, I am trying to produce 8lbs/hr (0.0011Kg/s), does anyone know what torque and rpm I should be using to get that kind of mass flow rate?
what how can you make the barrel heater without the complicated staff, and is it possible to make the screw from a round tube. asking for the 3rd world country where not everything is easily found and if you find its very expensive so we are trying to look for cheaper ways to make the environment cleaner
hello Whats the size of the drill? 25mm ou 26mm diameter? because 26mm doesnt enter in my tube. Do you have an astuce to maybe clean inside ? Thanks in advance
I think this is amazing.
As a 3d printing company this would be a great benefit to anyone doing printing or making.
It's important we start to reduce the plastic waste.
And now with the vast filament selection. And mainly useless trinkets printed that are thrown away. We can now focus on recycling all of this
This is a very clear and precise description of a basic plastic injection machine. Well done!
Larry Lund this is actually extrusion

I'm an Erema operator for a large plastic recycler , you are very entertaining and skillful
Thanks for getting her done and not trying to explain physics and gear ratio and all the other things in the universe great job!
This was a very good video. Who knew that an extrusion machine would be so easy to make? Nice job, Dave!
This is cool, i work on large extrusion machines making vinyl window parts, its really amazing seeing this on a smaller scale, it kinda reminds me of our capstock extruders
The video is just excellent with easy to understand language for a common man to technically qualified. Thanks dear for the great presentation.
You guys are doing such a great job here, I have shared this channel as much as I can and appealing to donate to the cause. Good luck with your efforts.

WOW! You are the very type of genius I need in my life to measure up to what my imagination wants to create with disgarded plastics!
You are very handy. And the wood drill idea is just amazing.
Thanks Dave. Can you use other types of heaters? You are so kind in making these videos, and with subtitles! From Argentina I reiterate my gratitude.
for people doing this...try to use a coupling, and you can use the same motor and gearbox for the shredder too.

Really excellent video and design and the only criticism is please wear safety glasses to protect your eyes when machining.
Even if I weren't as bad as I am with mechanics, I can't afford this amount of work and neither can pay for all the tools you used. But, I would like to have a machine like this at home.

damn, this is the real man's job,where one could forge so many machines and devices
Very informative and entertaining video Dave, on the subject of modifying and hacking this machine's orientation is very similar to horazontal injection molding machines, if clamping force and an assembly for the mold holder/ part ejecter can be drafted this could turn into an automated or semi automatic injection molding machine instead of the labor intensive hand operated one.
Hey,
I thought about building one of these machineries, because I like the Idea,
but isn`t it almost impossible to clean this mechanism, because of the molten plastik everywhere ?
May you publish a video, showing a cleaning-process please ?
Thanks for Answers in advance
Muchas gracias, tu forma de explicar es muy clara y me ayuda en la construcción de la extrusora. Gracias por compartir tus conocimentos
Lograste hacerlo ,eres técnico en torno algo así ?
Man you made my whole day was looking for something to do... after watching your website intro video Its amazing im joining the map. Thank you.
if everybody decided tor recycle plastic like that instead of just throwing it out there wouldnt be any in the ocean people need to stop looking at plastic like its trash but rather like a materials that can be recycled indefinitely to make all sorts of stuff like tables car parts tools etc
Hello !
I'm almost done building everything
I just have a problem with wiring everything
I'm very bad at this and tried to find at the forum but couldn't
help would be very appreciated
Thank you for this amazing idea !
The temperature controller PID you're using should have a wiring diagram. That's pretty much all you need.
Español
Inglés
You are a genius, I hope you continue making machines, I wonder if that system is the same to make balanced food in pellets.
great presentation can possible make pipes for irrigation purpose from plastic waste
wood drill...damn, that's so good idea! I was thinking of some kind of huge threaded rod , but this is much better. Thanks for inspiration! ^^
Excellent sir,may God bless you
Thank you. It's very interesting. I'm at Brazil and works with recyclin
In joy the video thanks for shearing. I have a welding tip grinding where you are going to weld will make the weld stick better. Look better. And you won't have as much build up. Less inclusion in welds. Anyway just my 2 cents.
I like your recycling centre. Our local council stopped public picking through stuff due to insurance risks.
Really good lesson, very easy way to explain. Thanks
Good job
Can you provide me the measurements of heaters and from where can I get them please
A person could probably adapt a arduino to control the temp and feed rate! Great video!
a person just did
Son,I am proud on you! I know what I need to do now!Thanks
Excelent video! Thanks a lot from Argentina
Amigo soy estudiante de universidad y me gusta mucho este proyecto pero los planos no estan en la pagina, ¿tendras un link donde pueda descargar toda la información, planos y diagramas para hacer la mía ??, gracias.
Awesome! can you give me the link to download technical information?
A one-man factory... very impressive!
wow that warehouse is heaven !
Really nice video, i want to build something like this and I was wondering if you have any problems with air bubbles trapped in the material and with the fumes that come out from the melting process
If we want to build this kind of small maching to make PVC Pipe or PPR pipe, what should be our ideal Barrel Dia and Lenghth?
Big thumbs up on this build 👍
Excellent video! I've been struggling with something similar for some time. What would you estimate the maximum diameter of extruded material would be?
Parabéns pela iniciativa! Esta ideia poderá ajudar muita gente.

hello very good job,. Would you pass me measurements or does the auger have any grip on the output end?
Thanks man! You are so smooth getting it done, wonder if I can do them as easily as u did. I need something slightly bigger. I need one that can make a 2'' elbow. Can you do it? I hoping to pay for both the extruder and mold. Please let me know what you think.
I am gonna do something big with this,
Thanks Dave.
You can really use it to make filament for the 3D printer? If yes, how many meters in one hour?
Dude you're incredible. Amazing vid.
Excellent design of nozzle - easy to fabricate.
Great video...definitely food for thought...good job well done...I would love to have a go at this...might need to develop some new skills along the way and find some work arounds but this looks doable...
Excelente video muchas gracias por compartirlo 👍 SALUDOS DESDE ECUADOR 🇪🇨👌🇪🇨
How about precision and repeatability of produced filament? Can this machine be used to produce perfectly round filament suitable for a 3D printer (1.75 or 3 mm with 2% tolerance)?
with the right nozzle, its possible
I dont think so because there is no reglulation exept the manual pulling, heat and the skrew at the nozzle.
(it would be pretty inconsistent)
I think you could do that, but you need to enable stable positioning of the extruded filament at least to the distance from the nozzle where it has solidified. You cuold do that by winding the filament at a distance from the nozzle. This can be done with a motor operated mandrel. However I can guess this is not too simple because the winding needs to be done at the same speed of the filament extrusion, and as the filement winds, the mandrel rotation needs to be decreased accordingly. You would need to control motor speed electronically.

In vertical extrusion you won't have this effect.
litle hard work . you can do it th-cam.com/video/Qlys045ut6U/w-d-xo.html
No it would not meet your 2% tolerance. By using a drill bit and not a true extrusion screw you will get air bubbles in your filament.
your a amazing engineering inventor .excellent video
Very high build quality
is it possible to get your electrical assembly manual? I'm trying to do the same but it doesn't work.
Can we add a hose nozel??? To make tubes and hoses.
Hi, I'm from Argentina. I congratulate you on the project. I would like to know how many hours it takes to extrude a kilo of material for both filament and wood. I thank you and I hope to get more in touch with you soon.
Very interesting stuff, I would go for a counter-rotary extruder for ABS/carbon....I need to build one!! Thanks for the ideas!
Then, you can create your own ABS filament for a 3D printer.
Very good job man!!! 👍👍👍💪💪💪
Good afternoon, I really liked the project, I just wanted to know how to calibrate the worm with the drum or tube so that the worm does not pink with the drum?

Would love to see 'recycling stations' around the globe, where people can bring their plastic and walk off with some crafted things!
Anyone up for teamwork near Bochum?
Thanks for the video. is it possible to extrude 1.75mm filament for 3d printing with this?
about..3d printer filament...how does it actually performs?anyone used this in 3d printing? and how precise u can get from this machine?
Você é incrível, saiba que aqui em manaus município localizado na amazônia brasil, você tem uma fã.
Gracias Dave , tus videos son muy claro , dan ganas de comenzar a reciclar el mundo.
Keep coming back to this maybe make one one day
that is very cool. great instructions.
You have some great fabrication skillz!!
Why i can see any gas(steam) with the molten plastic. And is there any foul smell?
Yes, in USA, a 1/2" variable speed drill is good enough, eh ?- - just make a simple jig on the trigger using a lock nut and bolt, so you can turn the blot into the trigger to up the RPM's, lock the bolt in place with locknut so it does not vibrate off

¡Hola! Una duda. ¿De cuánto voltaje son las resistencias y dónde las puedo conseguir más económicas? Al igual del motor,¿de cuánto voltaje es y dónde puedo conseguir uno semi-usado más económico?
I don't understand. The "empty" screw volume must decrease towards the end. When using the wood drill bit the volume is constant across its length
U da man my friend! Blessings to all of creation!
Absolutely awsome!! Very, very nice. Congrats!
Auger bit is cool but i guess it doesn't hav the ability to compress like a conventional extruder screw does so who should i contact if want to get made a real extrusion screw of normal size ?
cnc milling or cnc lathe or normal lathe will do the trick..? and how much it would probably cost.?
what a skill..hope i can be like him..where did u learn all the cutting and stuffs?
Could you use this method to do large injection molds? And if it has an issue of cooling down to quick just use a heated mold?
Alpha Nerd this is too slow. It is for extruding filament. Precious Plastic got another machine for injection molding. It's even easier to built...the thing nit so easy are the molds. larger molds are even more complicated.
well im thinking with his method of injection molding, you only have one plunge. Unelss you keep the whole mold at liquid temp.
Alpha Nerd with an extrusion molder you need a higher capacity to continuously melt a given amount of material while keeping the injection rate high.
How big a part are you trying to mold? Injection molding tools are rather sofisticated including cooling and heating For bigger parts like Bobby cars (HDPE) other techniques are used. they are made from hoses and blown up in the tool.

Which must be the distance between nuzzles inside and the end of the drill?
hello
Whats the size of the drill? 25mm ou 26mm diameter? because 26mm doesnt enter in my tube. Do you have an astuce to maybe clean inside ? Thanks in advance
Cómo puedo ver los videos anteriores a éste, ví que hay siete anteriores. Gracias
Excellent job Dave, thanks.
Hi Dave
The video is great. Do you think that your extruder design would work with fg filled nylon?
Thanks
Peter
any tips on sourcing a bigger auger screw? would be nice for extruding eps
In the website it says: " Max running time: 4H/Day". Why? What can be done to work for multiple hours, or days?
Nice video, use green sceen on that board haha nice don!
