Polyformer is an open-source, 3D-printed machine that recycles PET plastic bottles into 1.75mm FDM filament for 3D printers. It is primarily a hardware design (build guides, firmware, and G-code) built from 3D-printed parts and common 3D printer components, certified by OSHWA.
Use cases
- recycle PET water bottles into 3D printer filament
- build a DIY filament extruder from 3D printed parts
- turn plastic bottles into 1.75mm FDM filament
- make 3D printing filament at home from waste plastic
- build an open-source plastic recycling machine
- spool recycled filament for use on an FDM printer
When to choose
- you want to recycle PET bottles into your own 3D printer filament
- you are a maker comfortable sourcing parts, printing parts, and assembling electronics
- you want a modular, open-source hardware design you can modify
When to avoid
- you need a supported, actively maintained project (development ended in late 2025)
- you want a turnkey commercial product (it is build-it-yourself only)
- you are not comfortable working with high-voltage components and hot ends above 260C
- your 3D printer cannot print above 260C or has a PTFE-lined hotend
