3D-printing with PET Bottles

Yannik Dumon, Timo Keller

project report

We are both fascinated by the diverse application opportunities of 3D printing. However, 3D printers and the required filaments are very expensive. As there are still PET bottles without bottle deposit we thought that these could be cut and used as filament. Therefore, we want to develop a 3D printer that cuts these bottles into a thin plastic filament and feeds it into a homebuilt printing apparatus. The finished printer should be able to print points at specified xy coordinate positions on a platform.
