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