Abstract
A build material escapement assembly for an additive manufacturing system includes a retaining plate for coupling the build material escapement assembly to the additive manufacturing system. A base having a plurality of ports is disposed beneath the retaining plate, and a support frame is disposed within the base. A diaphragm is disposed around the base, and a retractable plate is disposed between the support frame and the diaphragm. A top plate is further coupled to the retractable plate through the diaphragm and a plurality of connectors are coupled to the plurality of ports of the base. The base, support frame, diaphragm, retractable plate, and top plate define a cavity, and the top plate is movable between a retracted position by applying a negative pressure and an extended position by applying positive pressure to the cavity via the plurality of connectors.
