Patent ID: 11794241

Abstract:
A method of printing a three-dimensional object. The method comprises: supplying a print material that is electrically conductive to a plurality of ejector conduits arranged in an array, the ejector conduits comprising first ends configured to accept the print material and second ends comprising an ejector nozzle; advancing the print material in one or more of the ejector conduits of the array until the print material is disposed within the ejector nozzle of the one or more ejector conduits; providing a flux region in the print material disposed within the ejector nozzle; flowing electrical current through the print material in the flux region to thereby generate a Lorentz force on the print material and eject at least a portion of the print material from the ejector nozzle onto a print substrate; and repeating both the advancing of the print material and the flowing electrical current through the flux region to form a three-dimensional object on the print substrate.
