%X Additive manufacturing via powder bed fusion – laser beam (PBF-LB) enables the fabrication of complex ge-ometries but suffers from inherently rough surfaces and surface tensile residual stresses, both of which cancompromise structural integrity, particularly under fatigue loading. To address these limitations, this study in-vestigates chemical mechanical polishing (CMP) as a surface finishing method for improving surface quality andmodifying the residual stress state in PBF-LB 316 L stainless steel. The work uniquely examines how scan rotation(0◦ vs. 67◦ rotation) and contour parameters influence CMP effectiveness in material removal, surface smoothing,and subsurface stress redistribution. With a targeted material removal of 110 μm, CMP reduced surface rough-ness (Sa) by up to 94
