Title (EN) PNEUMATIC JETTING OF METAL FOR ADDITIVE MANUFACTURING
(FR) PROJECTION PNEUMATIQUE DE MÉTAL POUR FABRICATION ADDITIVE
Abstract:
(EN) Devices, systems, and methods are directed to the pneumatic ejection of liquid metal from a nozzle moving along a controlled three-dimensional pattern to fabricate a three- dimensional object through additive manufacturing. The metal is movable into the nozzle as a valve is actuated to control movement of pressurized gas into the nozzle. Such movement of metal into the valve as pressurized gas is being moved into the nozzle to create an ejection force on liquid metal in the nozzle can reduce or eliminate the need to replenish a supply of the metal in the nozzle and, therefore can facilitate continuous or substantially continuous liquid metal ejection for the fabrication of parts.
(FR) La présente invention concerne des dispositifs, des systèmes et des procédés pour l'éjection pneumatique de métal liquide depuis une buse se déplaçant le long d'un motif en trois dimensions commandé pour fabriquer un objet en trois dimensions par fabrication additive. Le métal peut être déplacé jusque dans la buse lorsqu'une soupape est actionnée pour commander le mouvement de gaz sous pression jusque dans la buse. Un tel mouvement de métal dans la soupape à mesure que du gaz sous pression est déplacé dans la buse pour créer une force d'éjection sur le métal liquide dans la buse peut réduire ou éliminer le besoin de réapprovisionner une alimentation en métal dans la buse et, par conséquent, peut faciliter l'éjection continue ou sensiblement continue de métal liquide pour la fabrication de pièces.
