This study examines the fabrication of toothed wheels from 316L stainless steel using powder bed fusion (PBF), evaluating surface roughness, dimensional fidelity, and mechanical performance in the as-built condition. Results reveal near-net shape (NNS) accuracy, within ± 0.05 mm of the intended geom...
