Additive Manufacturing (AM) is considered one of the most important emerging technologies in the last years and it is developing more and more in the industrial field, considered an important pivot of the industrial revolution 4.0. The substantial difference from traditional technologies, considered subtractive, is that the part is built one layer at the time. Each successive layer is bonded to the preceding layer of melted or partially melted material. This allows lighter, more complex and more performing components, but at the same time the potential offered freedom is limited when complex geometries are printed. Additional support structures are often required in order to sustain overhanging parts but also to reduce the thermal warping, to minimize the residual stresses and to dissipate the heat generated during the melt.
