Abstract
L’invention concerne un procédé de fabrication d’une pièce par fusion sélective ou frittage sélectif de poudre à l’aide d’un faisceau de haute énergie, comprenant les étapes consistant successivement à : a) déposer une couche de poudre sur un support de construction ; b) fritter ou fusionner la couche de poudre à l'aide du faisceau de haute énergie selon un motif correspondant à une section de la pièce et/ou à une section d’au moins un élément sacrificiel de maintien de la pièce ; c) répéter les étapes a) et b) jusqu'à la réalisation complète de la pièce ; d) séparer la pièce du support de construction (8) et retirer l’éventuel au moins un élément sacrificiel. Le procédé est caractérisé en ce que la couche de poudre déposée à chaque étape a) a une densité relative comprise entre 45 et 60% et est obtenue à partir d’une poudre ayant une répartition granulométrique avec un D10 compris entre 2 et 12 µm et un D50 compris entre 8 et 28 µm. Figure pour l’abrégé : aucune
