    Abstract: An ejector for an additive manufacturing printing system is disclosed, including an ejector body having a nozzle, a heating element to heat a solid printing material in the ejector, causing the solid printing material to change to a liquid printing material, and a piston disposed within the ejector body capable of translational motion. The ejector may include a segmented solenoid coil wrapped at least partially around the ejector body, which may be powered to cause the piston to translate along a longitudinal axis of the ejector thereby causing one or more drops of the liquid printing material to be jetted out of the nozzle. A method of ejecting liquid from an ejector is also disclosed, including melting a printing material within an ejector to form a liquid printing material, and moving a piston towards an ejector nozzle, and ejecting a drop of liquid printing material from the ejector nozzle.
