Material overview
PA11 is a bio-based nylon derived from renewable castor oil. It offers markedly higher ductility and impact resistance than PA12 with excellent fatigue life — ideal for parts that flex repeatedly or absorb impact without cracking. It prints support-free with a natural matte finish, and is common in snap-fits, clips, sports gear, orthotics and prosthetics, and living-hinge parts.
Highlights
- Very ductile — ~45% elongation
- Excellent impact & fatigue life
- Bio-based — renewable feedstock
- No supports — complex geometry free
