A method of manufacturing three dimensional parts using an inert gas

A method for manufacturing metal structures in which minute drops of a liquid metal are emitted from an acoustic device through an inert gas. The presence of the inert gas at the surface of the liquid metal prevent the formation of an oxide skin which would absorb acoustic energy and hinder droplet...

Zusammenfassung:	A method for manufacturing metal structures in which minute drops of a liquid metal are emitted from an acoustic device through an inert gas. The presence of the inert gas at the surface of the liquid metal prevent the formation of an oxide skin which would absorb acoustic energy and hinder droplet formation and emission. The droplets are then emitted towards a substrate, which may form as a carrier, where they may be used to form solder bumps, circuit traces, or accreted to form a three dimensional device.
