Title (EN) ADDITIVE MANUFACTURING WITH ENERGY DELIVERY SYSTEM HAVING ROTATING POLYGON AND SECOND REFLECTIVE MEMBER
(FR) FABRICATION ADDITIVE AVEC SYSTÈME DE DISTRIBUTION D'ÉNERGIE AYANT UN POLYGONE ROTATIF ET UN SECOND ÉLÉMENT RÉFLÉCHISSANT
Abstract:
(EN) An additive manufacturing apparatus includes a platform, a dispenser to dispense a plurality of layers of feed material on a top surface of the platform, and an energy delivery assembly. The energy delivery assembly includes a light source to emit one or more light beams, a first reflective member having a plurality of reflective facets, and at least one second reflective member. The first reflective member is rotatable such that sequential facets sweep the light beam sequentially along a path on the uppermost layer. The at least one second reflective member is movable such that the at least one second reflective surface is repositionable to receive at least one of the at least one light beam and redirect the at least one of at least one light beam along a two-dimensional path on the uppermost layer.
(FR) Un appareil de fabrication additive comprend une plateforme, un distributeur pour distribuer une pluralité de couches de matériau d'alimentation sur une surface supérieure de la plateforme, et un ensemble de distribution d'énergie. L'ensemble de distribution d'énergie comprend une source de lumière pour émettre un ou plusieurs faisceaux lumineux, un premier élément réfléchissant ayant une pluralité de facettes réfléchissantes, et au moins un second élément réfléchissant. Le premier élément réfléchissant peut tourner de telle sorte que des facettes séquentielles balayent le faisceau lumineux de manière séquentielle le long d'un trajet sur la couche supérieure. L'au moins un second élément réfléchissant est mobile de telle sorte que l'au moins une seconde surface réfléchissante est repositionnable pour recevoir au moins un faisceau du ou des faisceaux lumineux et rediriger l'au moins un faisceau du ou des faisceaux lumineux le long d'un trajet bidimensionnel sur la couche supérieure.
