Stop Throwing Away Plastic Bottles! Make 3D Printer Filament Instead (PETCraft)

In this video, I demonstrate the core process of converting plastic waste into 3D printing filament. While the pulling process is done manually in this demonstration, the heart of the machine is powered by a custom Arduino-based PID control system. Precision is key when recycling PET. My setup ensures stable and accurate heating, which is critical for consistent filament quality, even during manual operation. PID Temperature Control: An Arduino Uno manages the heating block with a custom-tuned PID algorithm to prevent temperature fluctuations.
