US Patent 11491720 Systems, devices, and methods for additive manufacturing

A de-powdering basket comprises an enclosure of at least one side wall and a bottom wall. The enclosure is configured such that, when the enclosure is disposed within a build box, the outer surfaces of the at least one side wall are substantially adjacent to the interior walls of the build box. The enclosure further comprises one or more apertures disposed within the at least one side wall, each of the apertures comprising a void that extends through the at least one side wall from an interior surface of the side wall to an exterior surface of the side wall. The enclosure may be configured to accommodate a build plate situated within the enclosure. Outer edges of the build plate may cooperate with inner surfaces of the side walls of the enclosure to prevent loose powder from passing between the outer edges of the build plate and the side walls.
