Abstract: A printer having a pump which includes an inner cavity which retains a liquid metal printing material, and a nozzle, where the nozzle is configured to eject a plurality of liquid metal drops, an actuation coil configured to supply a pulse to the liquid metal to generate an electromagnetic force upon the liquid metal, where the actuation coil supplies a pulse at a first time varying current pulse, where the electromagnetic force causes the nozzle to eject a drop of liquid metal. The actuation coil also supplies a pulse at a second time varying current pulse, where the electromagnetic force is not sufficient to eject a drop of liquid. A method for metal jetting in a printer is also disclosed where differences between the temperature in an upper portion of the pump and the temperature in a lower portion of the pump are minimized.

Abstract: A dross extraction implement for a printer is described. The dross extraction implement includes a cylindrical portion having a first section along a length of the cylindrical portion of the extraction implement having a first diameter and a second section along a length of the cylindrical portion of the extraction implement having a second diameter, where the first section is adjacent to the second section. The dross extraction implement is configured to be advanced into and retracted from an inner cavity of an ejector in the printer. A printer using the dross extraction implement and a method of using is also described.
