Abstract :

Nowadays additive manufacturing (AM) techniques are recognized to be promising technologies with an enormously growing of research activities in the scientific and industrial panorama. In particular, AM of metal parts and advanced net shape metal powder technologies provide marked economic and technical gains in the production of smallto- medium parts with materials difficult to be processed. Notwithstanding this, the efficiency of processes and supply chain is strongly influenced by the limited materials palette currently available on the market, the high costs and very high time-to-deliver of the powders, the quality and reproducibility modifying the features of the final components. In addition, the exploitation of manufacturing systems in industrial productions dictates high quality processes with efficient control strategies. Considering all these aspects, a deep knowledge of part redesigns and process optimization is necessary in order to enhance part quality and to obtain a cost reduction, for new applications or future perspectives from the point of view of the final users and new adopters of additive technologies. At the same time, the control and the optimization of material behavior in process and post-process conditions is fundamental for increasing AM industrial exploitation, together with the development of new materials, such as aluminium alloys and metal-matrix composites, nickel super alloys, titanium alloys and steels for laser-based AM, intermetallic materials and super-alloys for electron beam melting.
