Building The Precious Plastic Extruder 

Thanks man! Are you the one and only Mattia from PP ?😃

Yeah man, it's a lot of fun too ! 😃

not sure if i understand :)

Thank you so much! I am just starting to see what products I could make with that extruder. Stay tuned for my next update, just been trying out my first mould yesterday 😃 Good tip too btw !

Your first point is to heat the molten plastic before extrusion, do you mean heat it before going in the mold? Molten plastic should be hot enough by itself or what do you mean? The spray sounds very interesting! I tried all kinds of lubricants before but not sure if i tried silicon. Any recommendations? Thanks four your input man!

Reply...ugh...

Wow, that's crazy ! You would definitely need a lot of plastic, and they would have to look similar too. Nice idea though!

thank you so much!

Sounds like a solid idea but how to you get the steal/sand core into the hammer?

You can fix steel core into a metal tube. I think that bolts is a best idea.

Thanks a lot for the input. Yes insulation makes a lot of sense. I was also trying out heating the mould. Might cover that in the next video :)

Hey Amara, thank you so much! Sorry for my late reply by the way. Your idea sounds awesome! Making Pavers is a good idea when you want to turn around a lot of plastic waste. And they don't have to be totally clean either (which takes less work). However, I'm not sure if you can build a cheap extruder and get the results you would want. My setup works really well for putting in a lot of plastic. When the opening at the front is big enough, there's quite a bit coming through. I tried to make mine as cheap as possible and here is what it cost (if i remember correctly): - Extrusion barell and screw - around 250€ - Heating elements with electric box - 300€ - A coupling - maybe 50€ - An electric Motor - Mine was 600 but it is overpowered for an extruder because I've bought it for the shredder. Maybe you can try and find a used electric motor with similar specs? That would be a start to make things cheaper. Check out the video from precious plastic, they're using a wood drill as a screw and you could go with a steel pipe for the barell. You could get the heating elements for cheap online and build it together yourself or ask someone that knows electric stuff :) Hope that helps 😃

Great ideas mate! I had a small shovel in mind as well. I will start with tiny plant pots as soon as i can! Will have more videos coming up, thanks for your support man😃

What is the die of an extruder? I'm a little lost here. I'm not super keen on making 3D filament because it's so tough. I would love to get a penny board mold or something like that.

Yes, I would definitely love to make a penny board! Thanks for all your input, that's super helpful. I will upload another video of my progress with the beams soon.

thank you !!

Thank you Amie, a shelf sounds lovely!

Thank you!! for watching :)

Thanks for the hint! I will post a video of my attempt of making beams soon :)

That's a good one too :)

I don't know the amps. been a long time. But i have improved the design and will come with an update video soon!

I know what you have in mind. I tried to go in that direction but it didn't work. I will post an update video on those extruder tests soon. I think for this extrusion you are talking about you would need machines that are a lot bigger and that run for a whole day. It's kind of like making 3D filament right? you cool the extrusion right when it comes out and you end up with and endless beam. That was also what i was hoping for. But is definitely hard to achieve. You'll see in the next video :)

@@ARTVENTUREFILMS it is and isnt. but yes you cool the filament as it exits have been aextrusion tech for 20 years. wire cable and tubing. also made fillers wich is exact same as filament. awesome project though. i havr always wanted to make one for home

That's what i was also thinking! Will try it out

Thanks for your input Klaus! I will need it for my future improvement on the machine. Really appreciate it, thanks!

i think i now what you mean but then i also don't really know what you mean. Yes there's only this one bearing and yes, that bearing also prevents the screw from going towards the coupling. Is that what you meant? The design isn't perfect, but it works 😄✌🏻

That is genious my man! I always wondered why to build such a structure but a greenhouse seems like a perfect use case! 😃

@@ARTVENTUREFILMS Yeah but would like to build one .

I think my motor has 300 Nm of torque and it's alright for the shredder but the extruder definitely struggles with that. I can only extrude for 30min before it overheats. The motor I'm using has 2.2kW, 230V and around 75rpm output speed, if i remember correctly.

Hey dude, thanks a lot! You can try the bazar of precious plastic or alibaba. Send me a message on IG if you want more details.

precious plastic bazar :)

Yeah that's true. Which is why it's super hard to do and i don't think i will manage to get it done 😃

That's true! I will keep that in mind. Thanks for the tip!

Thanks so much !!

Yeah it's crazy, can't wait for the next session :) I don't either of them but my mate has a lathe in his basement and a CNC at work, so that's awesome !

Thanks, nice idea!

Hey there! Sorry for the late reply. I don't really know why no one is using a screen to filter the molten plastic. Sounds very plausible though. I'm not an expert. Just trying out the precious plastic approach to recycle plastic. Thanks for the advice. I will post an update on all my learnings soon:)

Don' need a filtering screen (a filter) for extrusions so big as this. All of the contaminants will just be trapped in the mixture. That is the joy of it. Throw any old shite into it and it will still be strong.

But yes, a heated mold is essential, especially for PET or any other semi-crystalline polymer. If if crystallises in the mould no amount of power will push it through.

@@joemulkerins5250 but this "trapping" is one reason for the ugly appearance ;-)

Seriously awesome ideas!! 😃 Chess pieces are probably one of the coolest things i have heard so far, but you need so many different moulds for that. game dice and guitar picks are just genious ! :) Thanks for your ideas Layla!

That would be awesome but I'm afraid that's too hard. maybe without the holes going through the middle.

Hey there! Yes that's true. I haven't been extruding because I have to fix my welding machine to weld a better connection for the beam mould but so far it wasn't easy at all. Dave makes it look so easy in his videos though ;) Thanks for your input! What moulds have you been doing?

@@ARTVENTUREFILMS I have moulds only for injection machine. I would be very satisfied If I could produce beams, with regular parameters in adequate time, but I still couldn''t cope with it.

@@copypaste815 Would love to see some of your work :)

They would be super heavy but it's a nice thought. Probably a bit smaller would be better :)

Good thoughts man! What do you mean by something under your gas stove? Just a sheet so that it sits better? Various difficulty is the point really. Many awesome plastic products but most of them difficult to make.

@@ARTVENTUREFILMS So it wont shift around. I have a portable gas stove and I usually put it on top of the fridge when I'm cooking. Also Coasters. Or Filament for 3d printing.

@@BloodAcidPro ahh right. That makes sense. thanks man :)

Thanks a lot Robert ! 😍

I think it was Alibaba (AliExpress is more for consumer products). Just reach out to people, they're super helpful. And have faith that things will arrive :) I think there's even one called precious plastic. It's not easy to know what products at which price and when they will ship but just ask them.

Check out Precious Plastic. Everything is open source!

Yeah that's true but making good filament is not easy and you need even more machines. I was thinking of buying a mould and just doing one object

Hey thankyou so much! I think it's a 2.2kw 230v motor. But it's not enough for proper injection, it heats up too quick. It's good enough for shredding though

@@ARTVENTUREFILMS Is that a 3 phase or 1 Phase induction motor?

@@mmnyako i don't know, sorry! Even after looking it up, I can't remember. And i wouldn't know which one is better either.

too long 😂 it was the first test run. Since then i've improved a bit. But i cannot give you a time because i'm not there yet.

Thanks for your ideas Jon! Nice thought with the frisbee.

Thank you so much man! How would you lubricate the mould? I think that's my biggest problem right now. Thanks for the tips too, I'm already working on improvements.

@@ARTVENTUREFILMS HDPE Is kind of selflubricating so that might solve it for that. But for other plastics, getting candlewax in the mold might be the least messy way i think.

@@olemi99 I didn't know HDPE would do that. Will test that for sure! Maybe waxing or lubricating it otherwise will be an option for PP, will see. Thanks for your input !

That would be crazy!!

Good thought, thanks William!

Awesome idea!

Alibaba 😄

You can actually find one made with the precious plastic measuring

@@ARTVENTUREFILMS as in the website?

@@IlanPerez exactly. I could look it up again if you'd like.

precious plastic bazar :)

I found it on alibaba actually. You can also search on the precious plastic bazar. Sorry for the late reply bro.

Thank you bro and no issue for late reply

always depends on if you build it yourself and only buy parts or if you buy it pre assembled. between 500 and 2K. Check out the bazar from precious plastic

you mean those 3030 aluminium profiles ? That would be crazy!

The coupling i bought from Maedler. Their page is the following: www.maedler.de/

@@ARTVENTUREFILMS thank you for your reply. what was the flange size for the extruder?

@@hackercabin190 I think it just has a small shaft where you attach the coupling. Are you also building an extruder?

I am building it it's awsome project that I hope seeing it finished I actually bought most parts and am half way there I guess, am stuck at the flange which the barrel get attach to it, the part between the coupling output and the screw. if you could offer guidance would be highly appreciated @@ARTVENTUREFILMS

@@hackercabin190 yeah man for sure! send me a message on insta. Maybe you can send a picture of the flange and where you need to attach it.

that would be sick! But I leave that to other companies. I'm currently in the making of building a mould (or letting someone else cnc machine it for me).

Great idea! I love things like this! But also the size is so hard to make with small machines..

Hey i would love to help but i don't have the time, i'm sorry. The internet is your best friend :)

I bought the shredder parts on the bazar. I have a video about the build if you're curious :)

Good Day, I have a design and wonder if you can help. It would be beneficial for both. it could be produced all over. I just wonder if you can make a plastic block 8" thick by 26" L and 14" H so I can shape it into my design , get it approved and patent it and then mass produced it. If you can, tell me how much will be and shipped to Georgia USA. Thanks Julio

@@inpeacewithgod Hey Julio, what's in it for me though? :)

@@ARTVENTUREFILMS If everything is approved I`ll make you like a franchise. I dont know where you from but here in America it can be used in every state and the world

What kind of shape though?

Your ideas sound crazy, but I'm not sure if i get what you mean. CMYKW printing sounds awesome but how am I supposed to pull that off? Same with the vinyl, how do you think to make a vinyl sheet extrusion? I've never seen any vinyl in my plastic waste. Thanks for your ideas nonetheless!

Crazy ideas are how society moves forward. Look at 3D printing itself because no so long ago it was a revolutionary crazy idea. So I've been watching tutorials of how vinyl is used to decorate all kinds of things. It always uses thin sheets that are cut by hand or machine into a flat shape and then the unwanted areas are picked out during the weeding and trimming process. This weeding stage is bad on the eyes and body over time. The vinyl that isn't used for a project is thrown away. Extremely wasteful process. Watching how Siser makes their vinyl their videos depict it in pellet / raw form whereby it is fed into a hopped and runs through an extruder. Watching videos of how vinyl records are made and they too use raw plastic pellets that are fed into a hopper and fed through an extruder to get the desired shape. Vinyl is described as having a rubbery gel-like quality once heated. 3D filament resin also comes in pellet form, is fed into a hopper, then run through an extruder to produce the shape desired. Usually as a thin string of plastic material but there is no reason it cannot be made into other shapes. This was the basis of my idea. By blending ideas of the desired outcome to create a "desktop" sized machine that can fabricate sheets of vinyl on-demand in the desired finished shape people would be able to eliminate the weeding and trimming process of decorating garments, signs, etc. Add the flexibility to precisely control the deposition of the vinyl like is done with solid ink printers means a page printer of vinyl working at much faster speeds as opposed to squeezing out a thin filament onto a heated plate to slowly build it up one layer at a time. While laying down precisely printed full color Cyan Magenta Yellow Black White in the desired shape one page sized layer for each pass you could layer those as well to create a much faster full color 3D extrusion vinyl printer. As to how you achieve that? This is why I asked if you can do it. I posed this question to several other engineers who use and build 3D printers, to Siser itself in the hopes this idea would get traction. Melted plastic and vinyl will conform to whatever shape it is forced through or molded as. Liquid resin 3D printers use a laser or high resolution LCD mask to produce each thin sheet of material layer by layer. But that process is a bit more involved requiring cleaning, UV curing, and sometimes post production treatments. It also tends to be a single color for the entire build.

@@IraQNid Seems like you've been in the topic for a while. Sounds like a good concept too. For me to pull this off would take a lifetime though. I'm not an engineer and if I'm not fully hooked by an idea, it's hard to put so much effort into a project. This seems to be directed in the shirt printing industry and they would definitely benefit from such an idea. It's not really what i would like to get into though. Thanks for your explanation. I hope you'll find someone that is keen on trying it out. Different question though, why aren't you trying it out yourself?

@@ARTVENTUREFILMS I'm not able to.

Yeah garden furniture makes sense! Wish I could live next to you, my neighbours suck 😂

Interesting idea! I don't have many roofs that need them though 😃

That would be cool!

Good idea :)

That would be great! You don't have such a machine i could borrow, do you? 😃

yes, that would be lovely, thanks!

Yes, a lot of flaws. And i already continued but haven't posted anything until now. I will try to make up for it and work on a video showing more of the process. Thanks for the motivation!

thank you so much! unfortunately i don't have the data on this. And i've been upgrading my machine the last couple of years, because it had a lot of flaws.

Thanks bro! Do you know someone that can help you build one of those machines? Maybe you can find an old motor somewhere? Not sure how I could help you dude.

Good Idea! Will put that on the list :) When I'm able to produce beams easily, it might be a good option!

how much for the whole thing?

hey david! I would try and see if anyone near you sells precious plastic machines. Precious Plastic has a bazar, where you can buy machines or parts for machines. Otherwise find skilled people that can build it for you? The technical specifications are all online.

good luck !

what is that ?

Yes, definitely possible but not easy. I would need another machine that could wind the filament in the right diameter.

yeaaah good idea !!

Yeah man, good thoughts! Raw materials is probably one of the most interesting things in my opinion. Thanks for your input! I'll be working on it :)

สวัสดีกลับมา

Yeah, i still do. I also have a bunch of footage of how it developed since i started. I'm working on another video too :)

What are dies? Yeah it actually would be better, not for big moulds though.

To do what exactly? Use as a seal? Thanks for your input :)

@@ARTVENTUREFILMS gaskets i use for cylinder heads nice and reusable

@@overbuiltautomotive1299 ahh right, thanks!

Not sure. If you can deliver high quality plastic flakes, that's probably something people who have machines would buy. If you sell molten plastic, it always depends on the shape and color. I guess it depends on what shape your molten plastic has.

I don't thinking many people are going to. It's definitely not easy and a lot of work too.

also nice idea dude!

go search for the precious plastic bazar online

how can i help?

@@ARTVENTUREFILMS can u like guide me from basic like what all things should i need or from where can i buy and then i could assemble those ...? 👉👈

@@jileshsoni9682 sorry man, I don't have the time for that. Check out precious plastic, they have all kinds of tutorials. And also you can buy pre-made machines on their bazar.

I know 😭 I did work on it a lot, and also filmed a lot. But no videos until now.. It will change soon!

@@ARTVENTUREFILMS please keep going!

That's true but how are you heating the aluminum? A friend can manufacture moulds and I might just have to pay him the material and his working hours. We're trying out the first mould right now. Thanks for the idea anyways! I have seen a video by precious plastic where they're using this technique to make a mould for climbing stones.

@@ARTVENTUREFILMS agree👍

Toilet seat is actually genius!! Maybe a little big but not a bad idea! What do you mean by wash hand?

Thanks mate! I was in Australia for 2 years. thats where it come from :)

Hi! Look at Precious Plastics website and youtube channel. They have tutorials and a forum for finding other precious plastic recyclers near you

thank you so much for helping out here :)

Send me a message on instagram if you need more specific help!

Thanks mate, I'll try to make some beams!

Nice one! 😃

Let's do it! Sorry for the late reply. Shoot me a message on Instagram :)

yes i realize this is 2 years ago

haha i'm also late to the party

Sounds like a solid idea. Unfortunately I don't know what to print 😂

Sounds hard though :)

Awesome stuff dude, thanks for your input ! I never heard of steering wheel tray but it looks handy 😁

@@ARTVENTUREFILMS yea I saw it somewhere and it seemed cool ..but yea hope u get some money back for the project

@@enriqueleft1785 Thanks man, will see how it goes :)

Great idea but what do i print though? 🤔
