Abstract: Some embodiments are directed to a multimaterial powder used in the field of metallurgy and plasturgy. The multimaterial powder includes support particles having a median particle size distribution between 1 μm and 100 μm and functionalising particles having a median particle size distribution that is a factor of 10 to 1000 lower relative to the support particles. The powder is characterised in that the support particles and the functionalising particles form composite grains having a core-shell structure that each have a core formed by a support particle, and a shell, that covers between 10 and 100% of the surface of the support particle and which is formed by at least one surface layer of the functionalising particles.
