Numakers PETG Carbon Fiber (PETG-CF)

Numakers PETG-CF reinforces PETG with chopped carbon fiber, adding the stiffness and dimensional stability your functional parts need while keeping the toughness that makes PETG resist cracking instead of just snapping. The result is a filament built for load-bearing work — drone frames, brackets, jigs, and automotive components — that holds tight tolerances with minimal warping. The carbon fiber texture conceals layer lines for a clean matte finish straight off the bed, so your parts look as engineered as they perform.

  • Strong, Stiff & Functional
  • Premium Matte Finish

Enhanced Strength and Stiffness

Standard PETG is tough but flexes under load. The chopped carbon fiber locks into the PETG matrix to resist that bending, raising rigidity and modulus so parts hold their shape under stress instead of deforming — while keeping enough give to absorb impact without cracking.

Chemical Resistance & Dimensional Stability

PETG-CF shrugs off the oils, greases, fuels, and solvents that degrade other materials, while the chopped carbon fiber lowers shrinkage and resists warping as parts cool. Prints come off the bed true to spec and stay that way — making it dependable for shop tools, funnels, fitted hardware, and parts that need a tight, repeatable fit around fluids and stress.
