Impact of single structural voids on fatigue properties of AISI 316L manufactured by laser powder bed fusion

•Defined structural defects were implemented in PBF-LB/M manufactured 316L specimens.•Individual internal defects (edge length ≥ 1,000 µm) lead to a significant reduction in UTS.•Material shows high defect tolerance against small internal defects during cyclic loading.•Applicability of the √area-par...
