Sir Cular is the hardware prototype of a filament recycling machine for Precious Plastic Portugal. Positioned behind a standard Precious Plastic extruder, it melts recycled plastic into endless possibilities for 3D printing. The system features a cooling unit, pullers with automatic speed regulation, and a winding mechanism. All components are 3D printed and screwed on an acrylic plate, fully customizable to allow continuous optimization and adaptation for future designs.

Initiated at OPO’LAP for Precious Plastic.

Brief

We have large amounts of sorted plastic sitting in the OPO’LAB workshop. Our current recycling machines offer only limited processing options. Could we build a new machine that would give us more flexibility for reusing this plastic?
