A new method with ultrasonic mechanism for efficient depowdering of parts produced by electron beam melting

Abstract: Among metallic additive manufacturing technologies, electron beam melting (EBM) requires a specific operation called depowdering once a part is built. With the help of a powder recovery system (PRS), this process consists in blowing titanium powder onto a “cake” of a manufactured part in order to separate sintered but not melted powder from the part itself. However, the depowdering of some geometries can in fact become difficult, even impossible, due to the part shape. This article aims at proposing an ultraso… Show more
