Designed a bottle-cutting contraption to slice PET bottles into uniform strips suitable for feeding into the extruder.
DIY filament extruder using RAMPS 1.4 board, dual 3D printer nozzles, and NEMA 17 stepper to convert shredded PET bottles into usable 3D printer filament.
Designed a bottle-cutting contraption to slice PET bottles into uniform strips suitable for feeding into the extruder.
Built the extruder using RAMPS 1.4 board, dual hotend nozzles for melting, and NEMA 17 stepper for controlled extrusion.
Implemented temperature control and extrusion speed tuning to achieve consistent filament diameter for reliable 3D printing.
Successfully produces usable PET filament from recycled bottles.
High temperatures involved. Use proper ventilation when melting PET. Wear heat-resistant gloves.
