    Abstract: A three-dimensional (3D) printing system includes a print engine chassis, a build box, a vertical movement mechanism, a powder dispensing module, a consolidation module, and a controller. The print engine chassis defines a build chamber configured to receive and support the build box. The build box includes a build plate upon which the 3D article is fabricated. The vertical movement mechanism includes a plurality of actuators configured to collectively provide precise positioning of the build plate. The controller is configured to (1) operate the vertical movement mechanism including operating the plurality of actuators to position an upper surface of the 3D article generally proximate and parallel to a build plane, (2) operate the powder dispensing module to dispense a new layer of powder over the upper surface, and (3) operate the consolidation module to selectively consolidate the new layer of powder.

    Abstract: An additive manufacturing system for producing a three-dimensional article includes a print engine, a post-fabrication powder removal apparatus, a transport mechanism, and a controller. The post fabrication removal apparatus includes a rotary frame defining an internal receptacle cavity, a plurality of clamps coupled to a corresponding plurality of actuators, a clamping plate coupled to a lift apparatus, and an agitation device mounted to the clamping plate. The controller is configured to perform the following steps: (1) Operate the transport mechanism to transport the build box to the internal receptacle cavity. (2) Operate the plurality of actuators to engage the build box with the plurality of clamps to secure the build box to the rotary frame. (3) Operate the rotary frame to rotate the build box until unfused powder begins to exit the build box. (4) Operate the agitation device to facilitate pouring of the unfused powder from the build box.
