Abstract

L'invention vise un procédé de fabrication d'une pièce (20) en métal, en alliage métallique ou en céramique par fusion sélective ou frittage sélectif sur lit de poudre, la pièce comprenant un empilement solidaire de couches de poudre fusionnées ou frittées par un faisceau énergétique, le procédé comprenant les étapes suivantes : le dépôt d'au moins une couche de poudre d'un métal, d'un alliage métallique ou d'une céramique destiné à constituer la pièce, et la fusion ou le frittage d'au moins une partie de la couche de poudre par le faisceau énergétique, les conditions de l'étape de fusion ou de frittage étant définies par un groupe de paramètres comportant : la puissance du faisceau, le diamètre du faisceau, et la vitesse de déplacement du faisceau. Les conditions de fusion ou de frittage sont modifiées pendant le procédé de fabrication en faisant varier au moins l'un desdits paramètres, ladite puissance du faisceau étant, si elle est modifiée, augmentée d'une première valeur à une deuxième valeur, ledit diamètre du faisceau étant, s'il est modifié, diminué d'une première valeur à une deuxième valeur, ladite vitesse de déplacement du faisceau étant, si elle est modifiée, diminuée d'une première valeur à une deuxième valeur, de manière à introduire localement dans la pièce des contraintes résiduelles.The invention relates to a method of manufacturing a part (20) made of metal, metal alloy or ceramic by selective melting or selective sintering on a powder bed, the part comprising an integral stack of layers of powder fused or sintered by a powder bed. energy bundle, the method comprising the following steps: depositing at least one powder layer of a metal, a metal alloy or a ceramic intended to constitute the part, and the melting or sintering of at least one at least part of the powder layer by the energy beam, the conditions of the melting or sintering step being defined by a group of parameters comprising: the power of the beam, the diameter of the beam, and the speed of movement of the beam . The melting or sintering conditions are modified during the manufacturing process by varying at least one of said parameters, said beam power being, if modified, increased from a first value to a second value, said diameter of the beam. beam being, if it is modified, reduced from a first value to a second value, said speed of movement of the beam being, if it is modified, reduced from a first value to a second value, so as to introduce locally in the part of the residual stresses.
