Abstract
La présente invention concerne un procédé de fabrication additive sélective, dans lequel on chauffe un lit de poudre par exposition sélective à un faisceau généré par une source de puissance, le lit de poudre étant constitué par dépôt de différentes couches de poudre successives, caractérisé en ce que pour plusieurs couches successivement déposées : - pour chaque dépôt de couche, on fusionne et/ou consolide la poudre au niveau d’une zone de contour de la pièce ; - on fusionne et/ou consolide une zone de cœur à l’intérieur des zones de contours ainsi définis, après dépôt de ces différentes couches et fusion et/ou consolidation des zones de contours de celles-ci, ces différentes étapes étant itérées pour constituer la pièce.
