Claim 18:
19. A method for metal jetting, comprising:
introducing a first inert gas into an outer nozzle of an ejector nozzle from a first gas source;
combining a powder with a second inert gas from a second inert gas source to suspend the powder in the second inert gas;
combining the powder suspended in the second inert gas with the first inert gas;
ejecting a droplet of molten metal printing material from the ejector nozzle;
introducing the powder suspended in the second inert gas and the first inert gas to the molten metal printing material via an additive inlet external to and coupled to the ejector nozzle;
allowing the combination of the first inert gas and the powder suspended in the second inert gas to react with the droplet of molten metal printing material; and
modifying a composition of the molten printing material with the powder during ejection to form a modified molten metal printing material; and
depositing a droplet of the modified molten metal printing material onto a substrate or a solid printing material.
