1. A vacuum additive manufacturing process for the production of complex shape non-oxide ceramics and ceramics matrix composites with ceramic reinforcements, the process performing in a single step the in situ synthesis, controlled densification and shaping of non-oxide ceramics as mono-phase like SiC or multi-phase like complex ceramic composite materials, said process consisting in one-step reaction of powdered, electrically conductive, metallic particles with powdered non-metallic particles in a production chamber, wherein the thermal energy is supplied by one or more energy sources, a powder bed is progressively deposited and the energy source is focused on said powder bed, generating heat and selectively melting said powdered metallic and non-metallic particles following 3D model data to simultaneously shaping and consolidating the desired component.
