Plastic Bottle to 3D Printing Filament Recycling Machine

The PET Bottle Filament Making Machine is a proof of concept model designed to transform discarded plastic bottles into high-quality 3D printing filament. It works by cutting plastic bottles into strips, feeding them through a heated extrusion module, and carefully spooling the resulting filament with precise control over temperature, speed, and diameter. The machine demonstrates sustainable engineering practices and practical recycling applications.
