Abstract
(EN)
An additive manufacturing device that uses one material out of a powder material and a linear material and forms a molded article on a base. The additive manufacturing device comprises: an additive material supply unit; a light irradiation unit; and a control unit that controls the supply of the one material, the irradiation of a light beam, and the relative movement of the light beam. The light irradiation unit includes a central light beam irradiation unit and an outside light beam irradiation unit. The control unit independently controls the output conditions for the central light beam irradiation unit and the output conditions for the outside light beam irradiation unit. The control unit: increases the peak in a power density distribution shape for the central light beam to greater than the peak in the power density distribution shape for the outside light beam; and forms a molded article.

L'invention concerne un dispositif de fabrication additive qui utilise un matériau parmi un matériau en poudre et un matériau linéaire et qui forme un article moulé sur une base. Le dispositif de fabrication additive comprend : une unité d'alimentation en matériau additif ; une unité d'exposition lumineuse ; et une unité de commande qui commande l'alimentation dudit matériau, l'exposition à un faisceau lumineux et le mouvement relatif du faisceau lumineux. L'unité d'exposition lumineuse comprend une unité d'exposition à un faisceau lumineux central et une unité d'exposition à un faisceau lumineux extérieur. L'unité de commande commande indépendamment les conditions de sortie de l'unité d'exposition à un faisceau lumineux central et les conditions de sortie de l'unité d'exposition à un faisceau lumineux extérieur. L'unité de commande : augmente le pic d'une forme de distribution de densité de puissance destiné au faisceau lumineux central jusqu'à une valeur supérieure au pic de la forme de distribution de densité de puissance destiné au faisceau lumineux extérieur ; et forme un article moulé.
