Title
(EN) SYSTEM AND METHOD FOR PRODUCING GRADIENT STRUCTURES IN A POWDER BED, AND ARTICLES PRODUCED THEREFROM
(FR) SYSTÈME ET PROCÉDÉ DE PRODUCTION DE STRUCTURES DE GRADIENT DANS UN LIT DE POUDRE, ET ARTICLES PRODUITS À PARTIR DE CEUX-CI
Abstract
(EN)
Systems and methods for making gradient structures via a powder bed, and a part produced therefrom are provided. For example, the system comprises a powder bed deposition region, a powder deposition module, and a joining module. The powder bed deposition region is adapted to receive powder and comprises a powder bed deposition surface. The powder deposition module is adapted to dispose a first layer consisting of a first powder in the powder bed deposition region, and to dispose a second layer consisting of a second powder in the powder bed deposition region in contact with the first layer. The first and second powders differ. The joining module is adapted to affix at least a selected region of the second layer to at least a selected region of the first layer.

La présente invention concerne des systèmes et des procédés de fabrication de structures de gradient par l'intermédiaire d'un lit de poudre, et une partie produite à partir de ceux-ci. Par exemple, le système comprend une région de dépôt de lit de poudre, un module de dépôt de poudre et un module de jonction. La région de dépôt de lit de poudre est conçue pour recevoir de la poudre et comprend une surface de dépôt de lit de poudre. Le module de dépôt de poudre est conçu pour déposer une première couche constituée d'une première poudre dans la région de dépôt de lit de poudre, et pour déposer une seconde couche constituée d'une seconde poudre dans la région de dépôt de lit de poudre en contact avec la première couche. La première poudre et la seconde poudre sont différentes. Le module de jonction est conçu pour fixer au moins une région sélectionnée de la seconde couche à au moins une région sélectionnée de la première couche.
