Powder remover for additive manufacturing machine

Abstract

The invention relates to a powder defoamer (1) for a powder bed fusion additive manufacturing machine (80) for manufacturing a part (90) comprising a base (91) and a top (92). This additive manufacturing machine (80) comprises a platform (81) extending in a plane (P) on which the base (91) rests after its fabrication. The powder defoamer (1) comprises a vibrator (10) adapted to vibrate the platform (81). The powder defoamer (1) further comprises a body (20), a first connecting element (30) adapted to secure the body (20) to the top (92) of the part (90) in a direction Z perpendicular to the plane P when the part (90) rests on the platform (81), and a second connecting element (40) adapted to secure the body (20) to the platform (81).
