The invention relates to a process for rapid manufacturing of parts made of a metallic, intermetallic or ceramic material, made of a ceramic matrix composite or made of a metal matrix composite with discontinuous reinforcement, especially with ceramic or intermetallic reinforcement, by melting or sintering particles of powder(s) using a high-energy beam. Characteristically, the powder used is a single powder, the particles of which have a sphericity of between 0.8 and 1.0 and a shape factor of between 1 and [square root of]2, each powder particle having a substantially identical mean composition and the particle size distribution of the particles of said powder is narrowed about the mean diameter d50% value so that: (d90% - d50%) / d50% <= 0.66 and (d50% - d10%) / d50% <= 0.33 with a "span" (d90% - d10%) / d50 % <= 1.00. Application to the rapid manufacturing of parts by selective laser melting (SLM) or by selective laser sintering (SLS) or else by direct metal deposition (DMD). Such powders are adapted to the targeted process/material pair.
