[EN] A method of manufacturing a part includes melting, rapidly solidifying and consolidating pre-alloyed powders using an additive manufacturing process. The method provides a finished part with a microstructure with at least one non-equilibrium phase. The pre-alloyed powders can be powders of aluminum alloyed with iron and molybdenum, and the additive manufacturing process forms a near-net shaped part that can be finished with techniques such as machining, polishing and drilling, among others. The additive manufacturing process can be a laser melting technique such as selective laser melting or laser metal deposition and an average dendrite arm spacing of the rapidly solidified and consolidate pre-alloyed powders is less than 1.0 micro m. Finished parts formed from the aluminum alloy powders alloyed with iron and molybdenum exhibit enhanced strength at elevated temperatures such as an ultimate tensile strength greater than 400 MPa at 300 degrees centigrade and greater than 350 MPa at 350 degrees centigrade

[EN] 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.
