Polymaker PolyWood is a reliable high quality wood imitation filament, with a diameter of 2.85mm. PolyWood is made entirely of PLA but looks like real wood. This material contains no real wood powder, so it can be printed with a 0.4mm nozzle or smaller without any problem.
PLA is an environmentally friendly and recyclable type of plastic. With this material you can easily print objects in any shape, in detail. PLA filament is harder and shinier than ABS. The ideal print temperature is 190°C to 210°C. For best results, use a heated bed of 25°C to 60°C.
