Some sample prints with our Laywoo-D3 wooden filament and a 0.5mm nozzle:
The Laywoo-D3 filament has a melting characteristic to PLA (180C-220C) and contains approximately 40% recycled wood. It can be sanded, drilled, glued and cut and reacts very similarly to wood. By varying the temperature at which you extrude you can control the coloration. Extruding at higher temperatures will cause it to darken. We have not encountered any warping during out test prints.
