Static and fatigue behavior in presence of notches for polyamide 12 (PA12) additively manufactured via Multi Jet Fusion™ process

•Static and fatigue behavior of MJF-PA12 were studied on notched/unnotched specimens.•Sharp notches: theoretical Kt much higher than experimental notch factor at failure.•Blunt notches had no impact on strenght with failure onsetting from internal defects.•TCD seems applicable to MJF-PA12 for quasi-static and fatigue failure prediction.•MJF-PA12 specimens showed similar fatigue strength to SLS or injection molded PA12.
