Abstract: A system for jetting metal is also disclosed, which includes a nozzle orifice in connection with the inner cavity and configured to eject one or more droplets of liquid metal, a source of printing material located external to the ejector, and an alloying system located between the source of printing material and the ejector. A method for metal jetting is disclosed, which includes introducing a printing material from a feed source into an alloying system. The method for metal jetting also includes depositing an alloying material within the alloying system onto the printing material to produce an alloyed printing material, introducing the alloyed printing material into an ejector defining a cavity which can retain a printing material, melting the alloyed printing material in the cavity of the ejector, ejecting the alloyed printing material from the ejector.

Abstract: A method for metal jetting is disclosed. The method for metal jetting includes introducing a first gas into an outer nozzle of an ejector nozzle from a first gas source introducing an additive to the first gas from a second source, combining the additive with the first gas. The method for metal jetting also includes ejecting a droplet of molten metal printing material from the ejector nozzle. The method for metal jetting includes allowing the additive to react with the droplet of molten metal printing material to form a modified molten metal printing material.

Abstract: An ejector for jetting modified metal is disclosed. The ejector for jetting modified metal also includes a nozzle orifice in connection with the inner cavity and configured to eject one or more droplets of liquid metal. The ejector for jetting modified metal includes a first gas source associated with the inner cavity and an external portion of the nozzle. The ejector for jetting modified metal also includes a second gas source coupled to the first gas source and in proximity to an external portion of the nozzle orifice.
