description	The present disclosure relates to a powder blend for use in additive manufacturing, which comprises a particulate metallic binder material, abrasive particles and a segregation-reducing additive for the powder blend, wherein the segregation-reducing additive comprises silica nanoparticles. According to another aspect, the present disclosure is directed to a method of manufacturing such powder blend and uses thereof. In still another aspect, it is provided a three-dimensional article obtained by treating such powder blend by irradiation with a focused beam. La présente invention concerne un mélange de poudre destiné à être utilisé dans la fabrication additive, qui comprend un matériau liant métallique particulaire, des particules abrasives et un additif de réduction de ségrégation pour le mélange de poudre, l'additif de réduction de ségrégation comprenant des nanoparticules de silice. Selon un autre aspect, la présente invention concerne un procédé de fabrication d'un tel mélange de poudres et ses utilisations. Dans un autre aspect, l'invention concerne un article tridimensionnel obtenu par traitement d'un tel mélange de poudres par irradiation avec un faisceau focalisé.
