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.
