Can 3D Printers use Recycled Plastic?

07/11/2018 at 16:20

I did some research about the type of plastics 3D printers can use, which said:

Many different materials can be used for 3D printing, such as ABS plastic, PLA, polyamide (nylon), glass filled polyamide, stereolithography materials (epoxy resins), silver, titanium, steel, wax, photopolymers and polycarbonate.

Because some of these materials can be recycled and processed by these machines, would it be possible to use the extruded to create a spool of plastic the printer can use? Has anyone tried this? I’m not quite sure if it would strong enough, could be extruded thin enough or would be flexible enough to be used but it would amazing if we could reuse that recycled plastic to create new pieces.

Let’s face it with recycling and I’m just looking for a way to create the crushing machine, follow up to continue with the extruder, my idea is the same, generate a filament thin enough to be applied to a 3D printer, of course said printer must have modifications so that the extruder of the same can heat to believe that … are more than 300 ° C so that it melts without generating gases.It is my final product, I hope that in a few years this is something common.

I 3d Print using filament made from recycled PLA, how ever at the moment there is a way of taking finely shredded plastics and extruding them directly through a 3d printer.

Here is one of the pellet extruders, I believe it still needs work but here is the link  https://www.thingiverse.com/thing:3032188

If been looking for the answer to this question too. According to a few websites i found it should be possible. For example this one:
At the moment i’m working on the extrusion machine of precious plastic. As soon as its finished i want to experiment first a little bit with PET to see if it is possible to make some workable 3D-printer fillament.

An advertised open source filament extruder from Plastic Bank.

there is another prototype here, i updated the dossier on the subject.

Also, I missed this topic before:
There seems to be an improvement coming in Version 4 (or later).
