Abstract: 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.

Abstract: A method for printing a 3D part includes decreasing a temperature of a build material in a nozzle of a 3D printer below a melting point of the build material, which causes the build material in the nozzle to transition from a liquid state to a solid state. The method also includes increasing the temperature of the build material in the nozzle above the melting point of the build material, which causes the build material in the nozzle to transition from the solid state to a sludgy state. An occlusion and the build material in the sludgy state are ejected from the nozzle.

Abstract: A method for metal jetting is disclosed. The method for metal jetting includes introducing a first gas into an outer nozzle of an ejector nozzle from a first gas source introducing an additive to the first gas from a second source, combining the additive with the first gas. The method for metal jetting also includes ejecting a droplet of molten metal printing material from the ejector nozzle. The method for metal jetting includes allowing the additive to react with the droplet of molten metal printing material to form a modified molten metal printing material.
