Composite materials (woodfill, copperfill, bronzefill, glow-in-the-dark, carbon or aramid composites and many others) consist of a main plastic base and a second material in the form of dust. These materials tend (except for wood composites) to be very abrasive, therefore a hardened nozzle is strongly suggested for long-term printing. A larger nozzle is recommended while printing with wood composites (0.5 mm and up). Please use corresponding print settings in PrusaSlicer as print parameters can be very different depending on the plastic base.
The first step in polishing is sanding. It’s a good idea to start with a coarse grit size (80) and slowly move up the grit table. After sanding, a big improvement in polish can be achieved with steel wool or a brass brush. If you’re still not happy with the finish, you can try wet sanding with a very fine grit (1500).
Easy to print
Needs hardened steel nozzle
Great look after post-processing
