Pros
  • Higher tensile strength than PA12
  • Excellent heat resistance (~130C)
  • Good chemical resistance
  • Outstanding toughness
Cons
  • Most hygroscopic common filament
  • Severe warping without enclosure
  • Requires large brim
  • Very difficult to print well
  • Expensive
Best For
  • High-strength mechanical parts
  • industrial fixtures
  • parts needing combined toughness and heat resistance
Avoid For
  • Humidity-exposed environments
  • cosmetic parts
  • open-frame printers
  • beginners
Storage
Vacuum seal between prints. Dry 16h at 80C. Absorbs moisture within minutes in humid environments.
Laser Compatibility
LASER INTERACTION Safety: DANGER — NEVER LASER nylon/PA filaments. Fumes: PA6 releases caprolactam (toxic vapour), ammonia, and various nitrogen-containing organic compounds when burned. Some formulations also release hydrogen cyanide. Warning: Caprolactam is acutely irritating to respiratory system and eyes. PA combustion also produces carbon monoxide. Never laser nylon parts.
