This thesis project is the result of the collaboration between Politecnico di Torino and Prima industrie S.p.A. The Group Prima Industrie operates in the field of mechanical industry, in particular it develops, manufacture and markets laser systems, sheet metal cutting machinery, electronics, CNCs components and additive manufacturing systems. This last field is the most recent and is managed by the newly constituted Prima Additive division. It deals with both Directed Energy Deposition and Powder Bed Fusion technologies. Directed Energy Deposition is an innovative Additive Manufacturing method that represents the evolution of the cladding technology. These machines are predominantly prototypes and, for this reason, process parameters must be evaluated and optimized case by case.
