How to recycle PET bottle into 3D printing filament?

Question

3D printers

What are the ways to recycle plastic bottles into plastic for a 3D printer. I understand that they need to be crushed first. I also read that you need an extruder. And what specific extruder is needed. How can it be collected. As a result, you need to get a thread of 1.75mm.

Answer 1

Bottles are easiest to recycle into a tape (there is a video on YouTube on how the Indians recycle), you just need to make the appropriate mechanism for feeding this tape to print. It is also possible to produce thread - by grinding, heating, pulling, cooling - the thread will be more expensive than tape

Answer 2

There is an option to buy an extruder that can recycle everything)) Something like this https://maind3d.wixsite.com/sait
