Abstract
A method for removing powder from a component or part produced by metal additive manufacturing systems based on powder beds. The method includes manufacturing a part by additive manufacturing, the part having at least one internal cavity with at least one external opening. The internal cavity is at least partly filled with powder, the powder in the internal cavity having grains agglomerated or connected to each other. The method further including: evacuating gas from the internal cavity; adding liquid electrolyte to the internal cavity, and using an electrochemical process for separating connected powder grains in the cavity.
