In the Additive Manufacturing field, the Electron Beam Melting (EBM) process is a relatively new technology. The use of a high-power electron beam to melt metal powder, in a Powder Bed Fusion (PBF) process, allows to produce complex parts made of excellent quality materials, overcoming the limitations proper of traditional manufacturing techniques, which result too expensive or difficult to be applied. ?? Nowadays, to fully exploit the potentialities of this technology, the optimization of process parameters is performed by means of an empirical try and error approach. Many efforts have been done to model the EBM process in a proper way and to make it more reliable, helping to reduce industrialization time, production costs and material waste.
