A build box associated with a powder bed fabrication system may comprise a housing defining a housing cavity, and a powder print bed disposed within the housing cavity. The powder print bed may be characterized by state information. The build box may further comprise a medium configured to facilitate access to the state information, and a coupling interface for removably engaging the build box with at least one subsystem of the powder bed fabrication system. The state information may comprise one or more state information elements of object identification, object location, current processing state, next subsystem processing step, previous subsystem processing step, object model information, object material composition, and current powder print bed temperature profile. The medium may comprise a memory device coupled with a transceiver. The medium may alternatively comprise an RFID device, or an optically perceivable designator, such as a bar code or QR code.

A system for de-powdering one or more objects within a powder print bed comprises a build box configured to contain the powder print bed, and a de-powdering subsystem configured to engage the build box. The de-powdering subsystem comprises a vacuum device configured to withdraw loose powder agitated by the air jet device, and a robotic arm configured to convey the vacuum device to one or more locations on the powder print bed. The system may further comprise an air jet device disposed on the robotic arm, the air jet device configured to agitate, with a jet of air, unbound powder within the powder print bed. The system may further comprise a mechanical agitation instrument configured to facilitate agitation of the unbound powder within the powder print bed. The mechanical agitation instrument may be used in conjunction with one or both of the vacuum device and the air jet device.

Automated de-powdering with robotically controlled vacuum

System including multiple instrument modules and arrangement thereof

A system for separating objects within a stacked powder print bed of nested objects comprises a build box configured to contain the powder print bed. The build box has a build box top and a build box floor. The system further includes an elongated aperture formed in a side wall of the build box, and a de-powdering subsystem configured to mechanically and electrically engage the build box. A separating blade associated with the de-powdering subsystem is configured to be inserted through the elongated aperture and into the powder print bed between a top-most print bed layer of the nested objects and a second print bed layer directly below and contiguous with the top-most layer, thereby forming an isolated powder print bed between the separating blade and the build box top. The unbound powder may be agitated by various techniques and subsequently removed from the objects.
