Abstract: A method of operating a three-dimensional (3D) metal object manufacturing apparatus selects operational parameters for operation of the printer to form conductive metal traces on substrates with dimensions within appropriate tolerances and with sufficient conductive material to carry electrical currents without burning up or becoming too hot. The method identifies the material of the substrate and the bulk metal being melted for ejection and uses this identification data to select the operational parameters. Thus, the method can form conductive traces and circuits on a wide range of substrate materials including polymeric substrates, semiconductor materials, oxide layers on semiconductor materials, glass, and other crystalline materials.

Abstract: A three-dimensional (3D) metal object manufacturing apparatus selects operational parameters for operation of the printer to form vias in substrates. The apparatus identifies the bulk metal being melted for ejection and uses this identification data to select the operational parameters. The apparatus identifies the via holes in the substrate and positions an ejector opposite the via holes to eject drops of melted bulk metal toward the via holes to fill the via holes.

Abstract: A three-dimensional (3D) printer includes an ejector and a coil wrapped at least partially around the ejector. The 3D printer also includes a power source configured to transmit voltage pulses to the coil. The 3D printer also includes a computing system configured to cause the power source to transmit the voltage pulses to the coil in intermittent bursts. The voltage pulses in each burst occur at a burst frequency from about 60 Hz to about 2000 Hz. The coil causes a drop of printing material to be jetted through a nozzle of the ejector in response to each voltage pulse. The drops generated in response to the voltage pulses in each burst land at substantially a same location in a horizontal plane.
