The 316 L stainless-steel samples were prepared by laser powder bed fusion (LPBF). effects of processing parameters on the density and defects stainless steel studied through an orthogonal experiment. was measured Archimedes method, optical microscopy (OM) X-ray Computed Tomography (XCT). microstructures under different LPBF OM SEM. results show that energy has a significant effect defect struc...
