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.
Claims19
A method for metal jetting, comprising:
- 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 and into an additive inlet external to and coupled to the ejector nozzle;
- combining the additive with the first gas;
- ejecting a droplet of molten metal printing material from the ejector nozzle;
- allowing the additive to react with the droplet of molten metal printing material;
- and
- modifying a composition of the molten printing material with the additive during ejection to form a modified molten metal printing material.
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.
