PLA / PETG (CF · GF) filament

Stiffer and stronger than standard PLA and PETG.

Sample part made from PLA / PETG (CF · GF)

What is PLA / PETG (CF · GF)?

Carbon fiber (CF) or glass fiber (GF) reinforcement increases the filament's strength, stiffness and temperature resistance. PETG CF/GF also offers higher impact resistance. It is preferred for industrial prototyping, engineering applications and functional parts.

Mechanical values vary with the reinforcement ratio; consult our engineers for your application.

  • High strength
  • Lightweight
  • High stiffness

    Carbon or glass fiber reinforcement gives much stiffer and stronger parts than standard PLA and PETG.

  • Dimensional stability

    Fiber reinforcement reduces shrinkage and bending; suitable for fixtures that need dimensional accuracy.

  • Attractive matte finish

    A matte, professional-looking surface that hides layer lines.

  • Industrial use

    A lightweight alternative to metal for fixtures, jigs, brackets and functional end-use parts.
