Description
PLA reinforced with chopped carbon fiber.
Common use cases
Stiff prototypes, fixtures, housings, dimensional test parts, and matte-finish components.
Advantages
Greater stiffness; excellent dimensional stability; attractive matte texture; hides layer lines.
Disadvantages
More brittle than many functional plastics; abrasive; not necessarily stronger against impact; limited heat resistance remains.
Printing tips and recommendations
Use a hardened nozzle; 0.6 mm is preferred for reliable flow and reduced clogging. Avoid a 0.2 mm nozzle. Dry before critical prints. Carbon fiber increases stiffness and dimensional stability but can reduce impact resistance and layer-to-layer toughness.
X2D guidance
The hardened-steel X2D nozzle is appropriate. Use 0.4 mm at minimum; 0.6 mm is safer for long prints and reduces clogging risk.
Support-material guidance
Support for PLA/PETG or Support for PLA (interface only); PVA; PLA-CF or PLA for ordinary supports.
