Printing orientation effects on microstructure in LPBF-manufactured SS316L subjected to fatigue

Year: 2025

Type: article

Abstract: In this paper, printing orientation effects on the microstructure and fatigue behavior of SS316L produced via Laser Powder Bed Fusion (LPBF) were studied. Specimens printed in Z (vertical), XY (horizontal), and ZX (45°) orientations were subjected to cyclic loading in the range from ± 300 to ± 500 MPa. EBSD analysis revealed that XY-oriented samples had superior fatigue resistance due to low-angle grain boundaries, while Z-oriented samples showed increased high-angle grain boundaries, leading to early crack initiation.
