KickStarter Project of the Week (KPW)

The next project is your own filament extruder for 3D printer. Basically, instead of buying expensive ABS filament, fabricate it yourself as it is cheaper to buy the raw material instead of the filament. Felfil. The main disadvantage… you have to use quite a lot a 3D printer in order to recover your investment, and it is not clear how the nozzle will be replaced when needed (it will age as a 3D printer nozzle will).
