I saw many 3D-prints fail during the process of printing at our school.
All these failed attempts were thrown away. The filament that was used was quite expensive.

Therefore I wanted to make my own filament maker to recycle the failed 3D-prints. The recycled filament that is extruded comes in 1,75mm or 3mm, depending on the nozzle that is used. I made the machine completely dismountable so if a part dysfunctions it would be an easy task to replace the part.
