Abstract

La présente invention concerne une imprimante 3D utilisant un filament d'alliage métallique, l'imprimante 3D introduisant un filament (650) d'alliage métallique à travers une buse (610) formée à l'intérieur d'une bobine (620) de chauffage par induction, fondant et extrudant le filament, et stratifiant le filament en trois dimensions à l'intérieur d'une chambre (500) chauffée à une température similaire. La présente invention introduit de manière forcée un filament d'alliage métallique dans une buse, chauffée par une bobine de chauffage par induction qui entoure de manière circulaire l'extérieur de la buse et forme un passage de refroidissement en son sein, au moyen d'un engrenage de transfert relié à un moteur de transfert. L'invention concerne une imprimante 3D pour filament d'alliage métallique dans laquelle est introduit un gaz inerte, afin d'empêcher l'oxydation d'un stratifié (520) d'alliage métallique, l'extérieur et la chaleur et l'air sont bloqués, et un filament (650) d'alliage métallique qui est fondu dans une buse et extrudé est stratifié couche par couche sur une plaque (510) de plancher placée à l'intérieur d'une chambre (500) chauffée et se déplaçant dans les trois dimensions par rapport à la buse, afin de fixer solidement le filament subissant peu de déformation.
