Abstract
A jetting assembly that can be used to print a high-temperature print material such as a metal or metal alloy, an aqueous ink, or another material, includes an actuator for heating a gas such as a non-volatile gas within a gas cavity. The actuator rapidly heats the gas within the gas cavity, which rapidly increases a volume of the gas, thereby applying a pressure to the print material within an expansion channel that is in fluid communication with the gas cavity. In turn, the print material within the expansion channel applies a pressure to the print material within a nozzle bore, which forces a drop of the print material from a nozzle. The jetting assembly further includes a supply inlet that supplies the print material to the expansion chamber and the nozzle bore, for example, from a reservoir.
