The Additive Manufacturing technology is based on a process of accretion of the component layer on layer and allows the creation of very complex geometries, difficult or not achievable with traditional technologies. Thanks to the advantages offered by design freedom and the continuous expansion of the variety of materials that can be processed, this technology is now beginning to take hold in the field of industrial manufacturing of metal components. In the context of metallic AM technologies, Selective Laser Melting (SLM) technique has been in particular adopted: after an initial distribution of a layer of metal powder on the building platform, a laser beam melts the powder following a calculated path. The platform is then lowered in order to permit the subsequent distribution of a new layer of powder. At the end of the process, the manufactured component can be extracted by removing excess unmelted powder.
