Title
(EN) SYSTEMS AND METHODS FOR ADDITIVE MANUFACTURING
(FR) SYSTÈMES ET MÉTHODES DE FABRICATION ADDITIVE
Abstract
(EN)
Systems and methods for additive manufacturing are provided. The method comprises depositing a layer of feedstock in a material deposition region of an additive manufacturing apparatus. At least a selected region of the layer is affixed together in the selected region. More specifically, energy is emitted from an energy source. The emitted energy is shaped utilizing an aperture. The shaped energy is transmitted to contact feedstock in the selected region in the material deposition region.

L’invention concerne des systèmes et des méthodes de fabrication additive. La méthode comprend le dépôt d'une couche de charge d'alimentation dans une région de dépôt de matériau d'un appareil de fabrication additive. Au moins une région sélectionnée de la couche est fixée ensemble dans la région sélectionnée. Plus spécifiquement, de l'énergie est émise à partir d'une source d'énergie. L'énergie émise est mise en forme au moyen d'une ouverture. L'énergie mise en forme est transmise à la charge d'alimentation de contact dans la région sélectionnée dans la région de dépôt de matériau.
