Kevlar Nylon

Advanced

Kevlar (Aramid) Fiber Reinforced Nylon

Kevlar nylon embeds chopped aramid (Kevlar) fibers into a nylon matrix, producing a composite with outstanding impact absorption, vibration damping, and wear resistance. Unlike carbon-fiber composites that prioritize stiffness, Kevlar nylon excels in applications where toughness and energy absorption are the primary requirements.

Nozzle Temp245–275°C
Bed Temp85–100°C
Print Speed25–45 mm/s

Printing Tips

  • A hardened-steel nozzle is required — aramid fibers are highly abrasive despite being softer than carbon or glass fibers.
  • Dry at 75 °C for 8-10 hours; the nylon base is very hygroscopic and aramid fibers wick moisture along their length.
  • Print in an enclosed chamber (45-55 °C) to control warping and maximize the toughness the aramid fibers provide.
  • Use moderate speeds (25-35 mm/s for walls) to allow proper fiber distribution and consistent extrusion pressure.
  • Increase infill density to 40-60% for impact-critical parts — Kevlar composites gain significantly more from infill than carbon variants.
  • Avoid sharp corners in your model design where possible; aramid fibers perform best in gradual curves and distributed loads.
