11.8 Composite materials
Composite materials (woodfill, copperfill, bronzefill, carbon or aramid composites and many
others) consist of main plastic base and second material in the form of dust. These materials
tend to be very abrasive, therefore hardened nozzle is strongly suggested for long-term
printing. 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
