PET Bottle to 3D Printer Filament Recycler

Concept

The project started from a simple question: instead of throwing away PET bottles and failed prints, can we turn them into new filament?

An old Ender 3 was dismantled and rebuilt as a compact recycling machine for PET plastic.

Process & Mechanism

Bottles are cut into strips, then fed through a heated extrusion system tuned for PET.

Careful temperature control and pull speed ensure a consistent filament diameter suitable for printing.

Impact

The system demonstrated a practical way to reduce waste and material cost while learning deeply about extrusion and materials.
