Over the last decade, Additive technologies have become one of the most interesting manufacturing techniques within the industry, particularly for metal techniques. Starting from the CAD file, Additive Manufacturing machines allow to produce any geometric shape without the usage of tools. Generally, the process is slower than convectional techniques, but it strongly depends on the geometrical complexity. What makes this process interesting are the many advantages it has, such as the reduction of components, the number of assemblies and the free design approach. There are several techniques available on the market for the fabrication of metal parts. The two main techniques are: Powder Bed Fusion (PBF) and Direct Energy Deposition (DED).
