PETamentor 3 – Full-Color PET Bottle Filament System
PETamentor 3 is the next evolution of the open-source PET filament machine, designed to turn everyday plastic bottles into high-quality 3D printing filament—now with full-color printing capabilities.
Building on the simplicity and efficiency of previous versions, PETamentor 3 uses a streamlined process: PET bottles are cut into a continuous strip, fed through a heated nozzle, and formed into consistent filament ready for 3D printing. The system remains accessible and DIY-friendly, using widely available components such as a motorized puller, adjustable cutter, and temperature-controlled hotend.
This new version introduces enhanced control and precision, allowing for full-color filament production, enabling full color prints (not just glass see-through ones) and expanded creative possibilities without relying on pre-manufactured filament. Combined with adjustable strip width and improved extrusion stability, PETamentor 3 delivers more consistent results across a wider range of bottle types.
Like its predecessors, PETamentor 3 emphasizes sustainability and cost-efficiency—transforming plastic waste into usable filament while reducing reliance on commercial spools. The open design encourages customization, experimentation, and community-driven improvements.
Whether you're prototyping, experimenting, or building eco-conscious projects, PETamentor 3 offers a powerful, low-cost way to produce your own filament—with color.

This project is a revival of the Dead PETamentor2 at https://petamentor2.com/
The Facebook group is dead and the forums are non-functional , and parts links no longer work
