Laser polishing for improving fatigue performance of additive manufactured Ti-6Al-4V parts

Additive manufacturing of metallic materials is rapidly growing due to the possibility of constructing customized products with complex geometries. The mechanical properties of additively manufactured parts often show inconsistent performance when compared against their wrought counterparts. The fatigue performance is often severely undermined by the presence of process-induced defects and in particular surface roughness, hence requiring a...
