Composite-filled filament combines a base polymer with fibers, minerals, metal or other particles. It changes stiffness, density, abrasion, surface and flow. The filler must match the function.

Common fillers

  • Carbon/glass for stiffness.
  • Metal for weight and heat.
  • Mineral for surface or density.
  • Wood for appearance.

Process effects

Abrasion, clogging and brittleness can increase. Use a suitable nozzle, dry the material and calibrate flow and retraction.

Common engineering mistakes

  • Using a brass nozzle.
  • Expecting all properties to improve.
  • Ignoring orientation.
  • Not drying.
  • Keeping the old profile.

Buyer checklist

  • What property is needed?
  • Is the filler abrasive?
  • Nozzle suitable?
  • Material dry?
  • Flow calibrated?
