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 Slic3r or PrusaControl as print parameters can be very
