Zusammenfassung:	The present invention relates to a method for forming a stereoscopic object (S). The method includes the steps of forming at least one powder layer by disposing forming powders (M) based on slice data, forming a material layer from the at least one powder layer, and laminating the material layer on a stereoscopic object (S) being produced. The powder layer is formed so as to have a thickness of less than twice a volume mean diameter of the forming powders (M) and to have a projection area percentage of 90% or higher per unit area. ' La présente invention se rapporte à un procédé pour la formation d'un objet stéréoscopique (S). Le procédé comprend les étapes consistant à former au moins une couche de poudres par disposition de poudres de formation (M) sur la base de données de tranche, former une couche de matériau à partir de ladite ou desdites couche(s) de poudres et stratifier la couche de matériau sur un objet stéréoscopique (S) en cours de fabrication. La couche de poudres est formée de façon à avoir une épaisseur inférieure à deux fois un diamètre moyen en volume des poudres de formation (M) et à avoir un pourcentage surfacique de saillies supérieur ou égal à 90 % par unité de surface.
