Precious Plastic - 3D printer Filament maker 

This is great, recycling my own plastic to use with a 3d printer. Not enough attention is pointed to your videos

Nice job, Dave! Excited to see this technology progress.

This will bring it full circle! Using trash to make practical items with a 3d printer! Awesome work!

More than 3 years ago, great job!

Great machine, better than expectec, I trust you. Good joob

Dave, again very impressive.

You are a hero, whether you know it or not!

...I think you're on a good track here! Success of your project depends on demand for a product - 3D printing might be the ticket. Good work - I wish you success.

You are in a next level men !

you're a genious man... trully

The introduction of a 3D shredder and 3D printer filament maker by Precious Plastic are tools that have the potential to revolutionize and revitalize the plastic waste industry in my opinion. Although the initial cost to build and the knowledge to construct may seem discouraging, I think, if a person has the monetary and mechanical potential, then the build will be most rewarding. As 3D printing grows in its use, so too will the need for its material... plastic filament. As the demand and consumption for plastic waste continues to decrease in China, formerly the largest user of American plastic waste, the US finds itself in a predicament with what to do with plastic scraps that must now, in turn, be sold to China. Yet, plastic waste material need no longer be a an expense to the US waste industry that ends up in landfills that have met their waste capacity. As a new tool, the 3D printer filament maker, may revolutionize the way Americans and other nations view plastic. The 3D Printing hobbyist and the like may view this a cash crop “harvest” waiting to be converted into a resource to meet the demand of maker 3D printing. Now one person's plastic waste can become another's precious resource. Plastic can now be turned into a material used in the 3D “printing” process making the recycling of plastics possible and accessible for the avid hobbyist to produce free filament for 3D Printing. In turn, production costs may be rapidly decreased for the hobbyist with such a material “free for the picking” out of the trash and into the workspace.

genial!! saludos desde Argentina!!

We need to spend $10 billion of research to turn that into a convenient internet-friendly home unit … like we did with phones.

very awesome this channel, go ahead sir

Nice job man! I would probably give the string a little bit of slack, so it doesn't stretch if you happen to turn up the winding speed by accident :)

It looks like candy :) Nice job !

Try making architectural parts and build homes!!! I just finished a master in architecture and I once went to Amsterdam to visit the 3D printed canal house! It was amaaaazing!!! :D There's a great future for 3D printed buildings, you must check that!!!

Really nice video! :)

Hi! Are all rod diameters compatible with 3D printing machines? Don't you have any trouble with some rod diameter irregularities? Do you aim a specific diameter? Thank you for all your videos! I love extrusion and recycling and you make it accessible to everyone, thank you for that!

Is there any feedback loop in the spooling system for diameter control?

Wow. Thanks bro.

Hi Dave, I'm wondering if you can make an 3D Printer? I want to do a homemade one, but it's kind difficult for me. The one on the video seems pretty good. Regards from Uruguay!

Please make and sell a kit to build this machine (and the shreder), not everybody can build this, even with blueprints, this thing has to go bananas 😉👍🏻

YOU ARE MY HERO

Hi folks! If you see this, I wanted to ask if your method for creating recycled 3D printing filament is working out long-term. I am looking at setting up my own precious plastic workshop with a focus on 3D printing and wanted to see if you consider that to be worthwhile. Love all that you do!

So when you 3D print, do you use your own filament? Or do you use something like MatterHackers?

Lekker bezig (:

Very nice, what types of plastics have given good results for printed parts?

Excelente!!!

Hı Dave. Congrulations.. What is the screw diameter? Which type of screw are you using? wood drill bit? or a professional screw? What is the hourly production capacity?

Good Job, But I have a question, what kind of plastic is used to do this filament, Just ABS of with others.

Hello, nice video bro. A question: What material are you using to make the filament ? and how thin can the filament be?

Acabo de terminar de escribir los subtítulos en español, ya que los aprueben, por favor, compartan el video de Dave =D !!!

Hi!!! I have a question. Ese filamento me sirve para cualquier máquina de impresión 3D o tengo que construir esa que parece al final cortada en Mdf a laser?

Thanks for your videos. You've inspired me to start collecting parts for my first extruder build! I am anxious to try making Polypropylene ("PP") filament, as you are doing in this video. I have, however, heard that PP can be troublesome to 3D print. So, I have a couple of questions: 1. Any suggestions for printing PP filament on a 3D printer (for example: extrusion & bed temps, print bed surface, etc.)? 2. Are any additives (like glass fibers) necessary to make the PP filament printable? Thanks again for all you efforts!

Have you seen the jigs to cup strings from PET bottles? I wonder if it would be possible to make 3d printer extruder, that would accept such flat string instead of round filament.

Great Machine! I've seen two built that are similar here on out. Russ @ rwg research has built one as well. Tell him HRM sent you.

Is it possible to extrude recycled PET from plastic bottles?

Nice Work. I would like to findout how to get the winder material or where to download files. Please help.

How far the drill need to stay to the nozzle?

is this PLA or ABS fillement? is the diameter correct for the printernozle

Where are the schematics of the filament production system?

Filament is one product that can be sold, but the way it is right now it would not be of consistent width. And apparently this is important for 3D printing. Rather then selling filament, I would sell pelets (bits of cut filament, not sure I got the word right) to other companies that know how to make products from recycled plastic. Sorting the plastic would be the most important task to be able to resell it. In my town we have one recycle center that pays about 1 eurocent / plasic bottle, and homeless people bring hundreds of bottles.

Hello! what kind of extruder performance?

Could you post the ebay link to your band heaters?

What firmware are you guys using? I love the winder.

Hello, I am a young man working on the extruder. What are the electronic components, i.e. the second part whose filament is wound into a coil?

If I want to make thread in order to create clothings out of PET, this machine works?

What kind of plastic you have used to make the filament?

I pledge to use all of your advice and videos to recycle while manufacturing within my small biz! How about making plastic sheets for vacuum forming??? This I could use! PETG, HIPS.. etc. Different thicknesses?

Really cool. Doesn't the spooled filament keep its "rolled" shape after you unspool it?

which program did you use for edit and animate the videos?

And how to process the PED bottles so that the thread is transparent?

Does anybody know how many kg or lbs of filament per hour can produce this extruder?. I can't find this info on the forum. Also, i'd love to see where I can see the filament winder on the forum. Many thanks.

what kind of plastic is being used and is their any limits on the plastic that is useable

The forum link doesn't work here. Where can I find the blueprints for this machine?

hi , i mad a plastic extrusion machine to produce 3d filaments (inspired by yours) but i am not getting out put in proper way please help me to solve this problem.

What kind of plastic did you used to make that

What kind of plastic was used?

In the video, you make polypropylene filament. Does that mean you 3D print PP with a FDM printer? I thought it was not doable. And how do you make sure to get a proper 3mm filament? And is that a e3d extruder on that Ultimaker, at the end of the video?

I dont see where i can make this one?

Hello Dave. I would like to know how well the extrusion machine works with PETs

Oye son un estudiante de ingeneria y quiero sabes de que tipo es el plastico con el que fabricas el filamento de impresora 3D Porfa

This is really fantastic. I am interested in making a machine. Can you help?

Hi, I'm a 3D printer user, always making some parts with Filament which PLA and TOUGH PLA. So, it remains some filament after prints. So, can I use this machine to get PLA and TOUGH PLA with recycling? If it's possible, how can I do it? For example, what temperature can I use? Thanks.

i got leftover gundam model frame plastics (a lot) , will it be good for filament ?

Where can I buy this filaments? I can't make the process at home and i would like to buy them ready, but i can't find them. Please.

Looks good. Has anyone tried comparing this to commercial filament?

where i can buy this your extruder setup? thx

hi , ineed all parts using after extrusion and coding

Hello everybody, I have a problem because Im trying to extruding, PLA but when the filament start to emerge of the extruder, the filament start to change properties and this turn fragile and I cant to roll up may you help me with an advice

plz give me link of your mould making video

el plástico Pet. si es compatible para una impresora 3d.? referente a su composición.? tengo entendido que es otro tipo de platicó que se utiliza.!! ayúdame explicando ya que deso aplicarlo

This is awesome! Can you use old wire/cable plastic? I’m currently building up a massive stock of copper.. obviously I will have endless amount of plastic left over..

las maquinas las puedes vender echas?

Do you think the plans for the final model of this machine will be released soon?

how much does the whole setup cost?

I am having issues using the flakes in the filabot which is the extrusion machine i am using. It works fine with pellets but the flakes are not catching completely in the extrusion screw. Any suggestions?

Website doesn't work and I was interested to do one at home

what type of plastics, and from what products is the material that you are using in this video? Thanks :)

Hi all, I need some help here. some kind of chemical treatment is needed to use the filament in a 3D printer?

hi do you have a DIY kit?

Hello Dave. Can I ask u something to know is this is going to work it for me so I could go on on research Is this machine able to work with PLA filaments. And recicle it

Where can I purchase filament?

hole is how many milimeters?

Very cool! It's okay if we build something like this using your design?

This is what I was looking for! But please don't just grab in the hopper of a running machine. That freaked me out.

Can any 3d printer use these filaments? I understand that for example the HDPE shrinks at the moment of cooling

How are you? In a 3d printing opportunity ask about the recycling of the plastic used and I was told that the plastic already used for printing loses characteristics. Whether of hardness, flexibility, etc. Depending on the material. How about that?

Open source? Wanneer kunnen we hem gaan maken?

two questions : 1. Can I extrude HDPE with this machine ?? 2. Can a 3d printer use HDPE for printing ??

What's the Filament Diameter you are using? It's possible to adapt to 1.75mm?

I'm curious to know if anyone has successfully done 3D printing with filament from this process. Another video here on RU-vid (and comments elsewhere by people who do a lot makes the case that the filament has to be very consistent in diameter to produce a successful print. The current PP extruder would seem to be very good for making pelletized plastic for use in an injection molding machine, where dimensional tolerances are less critical. For sure, progress in these things is in a series of incremental steps, and you have to start somewhere!

How much it cost ?

why flatten the filament at the end ? I read printers need round ones instead what printer are you using ? Is this the best for recycled plastic ? Thanks :)

How is the diameter consistency guaranteed? I may do this for my local area but i cant find proper informations thanks

Can this machines crush a car tyres

Интересно. Как са синхронизирани двата мотора ?

I'd love to make this, where can I get more information

Is this real? How the material made is different from PETG? Is this real PET recycled and extruded into filament?
