Description
The provision of the metal raw material (due to a low product yield) and inert gas consumption are the main energy consumers in powder production for additive processes. In standard gas atomization processes, any effort to produce finer powder (to increase product yield) is achieved by increasing inert gas consumption.
In order to decrease the carbon footprint of additively manufactured parts, a new powder production process was established at Metalpine GmbH. With the inhouse developed combination of melting system, gas atomization nozzle and closed gas circuit, high product yields are achieved at a strong decrease of gas consumption. The resulting powders are spherical, satellite-free and pore-free.
First evaluations of the printed parts show that the mechanical properties of the printed parts are compareable to the ones printed with powders from long-time established powder production processes.
