Title (EN) MAGNETOHYDRODYNAMIC DEPOSITION OF METAL IN MANUFACTURING
(FR) DÉPÔT MAGNÉTO-HYDRODYNAMIQUE DE MÉTAL LORS DE LA FABRICATION
Abstract:
(EN) Devices, systems, and methods are directed to applying magnetohydrodynamic forces to liquid metal to eject liquid metal along a controlled pattern, such as a controlled three-dimensional pattern as part of additive manufacturing of an object. The magnetohydrodynamic force can be pulsed to eject droplets of the liquid metal to provide control over accuracy of the object being fabricated. The pulsations can be applied in fluid chambers having high resonance frequencies such that droplet ejection can be effectively controlled over a wide range of frequencies, including high frequencies suitable for liquid metal ejection at rates suitable for commercially viable three-dimensional fabrication.
(FR) La présente invention concerne des dispositifs, des systèmes et des procédés destinés à appliquer des forces magnéto-hydrodynamiques à un métal liquide pour éjecter le métal liquide en suivant un motif commandé, tel qu'un motif en trois dimensions commandé, dans le cadre de la fabrication additive d'un objet. La force magnéto-hydrodynamique peut être pulsée pour éjecter des gouttelettes du métal liquide pour pouvoir commander la précision de l'objet en cours de fabrication. Les pulsations peuvent être appliquées dans des chambres de fluide ayant des fréquences de résonance élevées de telle sorte que l'éjection de gouttelettes peut être efficacement commandée sur une large plage de fréquences, y compris des fréquences élevées appropriées pour l'éjection de métal liquide à des vitesses appropriées pour une fabrication tridimensionnelle commercialement viable.
