In‑Situ Monitoring For Liquid Metal Jetting Using A Millimeter‑Wave Impedance Diagnostic

Joseph Bernadas

Published in the December 18, 2020 issue of Scientific Reports, this article describes a millimeter-wave diagnostic for the in-situ monitoring of liquid-metal-jetting additive-manufacturing systems. The approach provides information on droplet size, timing, and motion by monitoring a single parameter. Experimental results may promise a reliable in-situ characterization method for metal droplets.
