12.10 Composite materials
Composite materials (corkfill, copperfill, bronzefill, carbon or aramid composites and many
others) are based on the main plastic medium and second material in the form of dust.
These materials are very abrasive, so if you plan to print them long term, we recommend
using a hardened nozzle. When using wood composites, we recommend larger nozzles (0.5
mm and larger). The printing characteristics of each material may vary depending on the
plastic base, so use the appropriate print settings in the PrusaSlicer.
Postprocessing
The first step of polishing is sanding with sandpaper. It’s better to start with a coarse one
(80) and use finer and finer sandpaper. You can then sand the model with a brass brush. If
you are still not satisfied with the polish of the material, you can finally use the wet sanding
method with very fine sandpaper (1500+).
Advantages
Disadvantages
Great look after post-processing
Requires a hardened nozzle
No warping
May require a 0.6 mm nozzle
