摘要: The nozzles of a MHD liquid metal ejector/printhead can be clogged by contaminants in the liquid metal. Typically, these contaminants are in the form of small particles of aggregates of particles, such as metal oxides, that are insoluble in the liquid metal. Possible cleaning methods include mechanically removing the clogging material, such as by using a physical device to dislodge the clogging material and remove it; chemically removing the clogging material, such as by using selected chemicals/flux to chemically react with the clogging material; using ultrasound to break/remove the clogging material; and providing reversed and/or oscillating flow of material through the nozzle.
