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.
