### Melting 3D printed scraps: Burns up

PLA starts to char at about 220 °C. However, it also starts to soft at about 100 °C and becomes sloopy (and printable!) at 180 °C. Putting the oven to anything above 180 °C will, with the heating ...

### Print paper or cellulose - any recyclable filament?

Check Green-TEC by extrudr.eu is made from lignin (wood) or perhaps Algix Dura. They are both bio degradeable. Green-TEC ist my favorite because of less warping and fast printing.
