Monotonic loading and fatigue response of a bio-based polyamide PA11 and a petrol-based polyamide PA12 manufactured by selective laser sintering

- Mechanical and fatigue response of SLS petrol-based PA12 and bio-based PA11 at different ambient conditions.
- Independently of the conditions, PA11 showed better mechanical and fatigue behaviour than PA12.
- Fatigue response of PA12 does not vary with temperature but PA11 shows an improvement at −50 °C.
- PA11 showed ductile cavitation and PA12 brittle crazing.
- Under water conditioned conditions, PA12 fatigue response was much worse than PA11.
