Machine Bottle PET
Print Profile(1)

Description
Introduction
I took inspiration from the PETamentor2 project, but I decided to personally design and draw all the 3D printed files to create a machine capable of transforming PET bottles into filament for 3D printers. The main goal is to create an economical, reproducible by anyone solution based on easily available components, with a total cost of about 30€
This machine allows you to recycle PET plastic bottles by converting them into reusable filament, reducing waste and creating a virtuous cycle of domestic circular economy

Project Goals
- Create an economical machine for recycling PET bottles
- Use common components and self-produced 3D printed files
- Allow anyone to build the machine with a maximum budget of 30€
- Make the project open-source, improvable, and replicable
General Operation
- The plastic bottle is cut into thin strips
- The strips are fed into a heated system (hotend)
- The plastic is extruded forming 1.75 mm filament
- The filament is collected and can be wound onto a spool

Estimated Costs
The project has been optimized to remain within a total of 30€, considering only electronic and mechanical components purchasable online. The costs of 3D printed parts are not included in the 30€, often underestimated but still real: plastic, machine time, electricity consumption, and hotend wear can affect the final cost
This choice is stated transparently to provide a real and honest estimate of the project, something many do not highlight
3D Printed Files
All files have been modeled from scratch to ensure ease of printing and assembly. They will be made available in .STL format
