Abstract
The powder bed fusion PBF is used in the fabrication layer-by-layer of metallic parts directly from a CAD file. Localized powder melting is obtained by a concentrated energy source. Fatigue tests of PBF Ti6Al4V were performed on smooth specimens produced with different orientations with respect to build direction using either a laser beam system (DMLS) or an electron beam system (EBM). As-built specimen were subjected the fatigue loading to understand and quantify the influence of the surface roughness and morphology. The original results are discussed on the basis of previous studies on the same material and processes taken from the literature.
