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.
