Carbon fiber reinforced PLA combines the ease of printing of PLA with significantly higher stiffness from chopped carbon fiber strands. It produces parts with a professional matte finish and improved dimensional stability. Requires a hardened steel nozzle.
Properties
- Stiffness — Much higher rigidity than standard PLA
- Dimensional Stability — Reduced shrinkage and warping compared to plain PLA
- Surface Finish — Attractive matte black appearance
- Lightweight — Slightly lower density than regular PLA
- Abrasiveness — Carbon fibers will quickly destroy brass nozzles
Best Practices
- Use a hardened steel nozzle — brass wears out within hours
- Nozzle size 0.5mm or larger recommended to prevent clogging
- Print at 210-220°C for best results
- Moderate part cooling (50-70%) for good overhangs
- No enclosure needed, prints as easily as regular PLA
- Store in dry conditions to maintain print quality
