Abstract

See full text

A method for capturing trapped powder from a part during an additive manufacturing process, the method comprising defining parameters for a part, the part defining an interior passageway defined by interior sidewalls, defining parameters for a powder removal cap, the powder removal cap comprising a body portion and a thin radial membrane connected to the interior sidewalls of the part, simultaneously creating the part and the powder removal cap via additive manufacturing, wherein the powder removal cap is created within the interior passageway and, upon completion of the creation of the part and the powder removal cap, the powder removal cap traps excess powder within the interior passageway, removing the powder removal cap from the interior passageway by breaking the radial membrane from the interior sidewalls to permit access to the interior passageway, and capturing the excess powder within the interior passageway.
