Notes

Carbon-fiber-reinforced Nylon 6, sold as Fiberon PA6-CF20 (formerly PolyMide PA6-CF — same formula). TDS V1.1: nozzle 280–300 °C, bed 40–50 °C, chamber at room temperature, cooling fan OFF. ABRASIVE — fit a hardened-steel or ruby nozzle (a brass nozzle wears out in ~9 h). Highly moisture-sensitive: dry 100 °C for 10 h and keep dry while printing. Optional annealing at 100 °C for 16 h improves strength and heat resistance.

Dry 100 °C for 10 h per the Fiberon PA6-CF20 TDS V1.1. Highly moisture-sensitive — always store and print dry (keep RH < 20%).

About Nylon

An engineering material: tough, abrasion- and fatigue-resistant, with good chemical resistance — used for gears, living hinges, and load-bearing parts. The two hard parts are extreme moisture sensitivity (dry before EVERY print) and high temperatures that need an enclosure. Carbon/glass-fiber grades are abrasive and require a hardened nozzle.

Good for
  • Gears and mechanical parts
  • Living hinges
  • High-wear / high-fatigue parts
  • Chemical-resistant components
Avoid for
  • Printing straight off an open spool (must dry first)
  • Brass nozzles with fiber-filled grades
  • Open-frame printers for large parts
