Abstract

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.

First claim

What is claimed is:

1. A build box for an additive manufacturing system, the build box comprising:
a housing having a plurality of side walls and a floor, the plurality of side walls and the floor cooperatively defining a powder print bed configured to contain one or more printed parts;
an actuator configured to move the floor along a vertical axis of the housing, wherein a volume of the powder print bed increases as the floor is moved along the vertical axis;
a transceiver operably coupled to a memory and configured to at least one of receive or transmit the information relating to the one or more printed parts to at least one subsystem of the additive manufacturing system;
at least one aperture formed in a side wall of the housing; and
a separator blade inserted into the powder print bed through the at least one aperture, the separator blade extending across the powder print bed and partitioning the powder print bed into a first area of the powder print bed located on a first side of the separator blade, and a second area of the powder print bed located on a second side of the separator blade.

2. The build box according to claim 1 , wherein the at least one subsystem of the additive manufacturing system is one or more of a central server, a user device, a binder jet fabrication subsystem, a de-powdering subsystem, or a sintering furnace.

3. The build box according to claim 1 , wherein the transceiver is a radio-frequency identification (RFID) device or an optically perceivable designator.

4. The build box according to claim 1 , further comprising:
a display operably coupled to the build box and configured to display the information relating to the one or more printed parts; and
a user interface operably coupled to the build box and configured to receive a user input for displaying the information relating to the one or more printed parts.

5. The build box according to claim 1 , wherein the information relating to the one or more printed parts is accessible both when the build box is directly coupled to the at least one subsystem of the additive manufacturing system and when the build box is not directly coupled to the at least one subsystem of the additive manufacturing system.

6. The build box according to claim 1 , wherein the information relating to the one or more printed parts includes one or more of a part identification, a part location in the powder print bed, a part model information, a part material composition state, a non-part material composition, a part position or orientation in the powder print bed, a powder bed density, a part quantity, a packed density, a current processing, a next subsystem processing step, a previous subsystem processing step, a beginning to end process flow, a failure status, a temperature profile, or a pressure profile.

7. The build box according to claim 1 , further comprising:
one or more sensors configured to detect at least some of the information relating to the one or more printed parts and to communicate the information relating to the one or more printed parts to the memory.

8. The build box according to claim 1 , further comprising:
a coupling interface for removably engaging the build box with the at least one subsystem of the additive manufacturing system.

9. A build box for an additive manufacturing system, the build box comprising:
a housing having a plurality of side walls and a floor, and an opening on an upstream side of the housing opposite the floor;
a powder print bed defined by the plurality of side walls and the floor, wherein the powder print bed is configured to contain one or more printed parts;
an actuator configured to move the floor along a vertical axis of the housing, wherein a volume of the powder print bed increases as the housing floor is moved along the vertical axis;
a radio-frequency identification (RFID) device configured to store information relating to the one or more printed parts; and
a coupling interface for removably engaging the build box with at least one subsystem of the additive manufacturing system; and
an aperture in one or more of the plurality of side walls.

10. The build box according to claim 9 , further comprising:
a display operably coupled to the build box and configured to display the information relating to the one or more printed parts; and
a user interface operably coupled to the build box and configured to receive a user input for displaying the information relating to the one or more printed parts.

11. The build box according to claim 9 , further comprising:
a transceiver operably coupled to a memory and configured to at least one of receive or transmit the information relating to the one or more printed parts to at least one subsystem of the additive manufacturing system.

12. The build box according to claim 11 , wherein the at least one subsystem of the additive manufacturing system is one or more of a central server, a user device, a binder jet fabrication subsystem, a de-powdering subsystem, or a sintering furnace.

13. The build box according to claim 11 , wherein the information relating to the one or more printed parts is accessible both when the build box is directly coupled to the at least one subsystem of the additive manufacturing system and when the build box is not directly coupled to the at least one subsystem of the additive manufacturing system.

14. The build box according to claim 9 , further comprising:
a separator blade inserted into the powder print bed through the aperture, the separator blade extending across the powder print bed and partitioning the powder print bed into a first area of the powder print bed located on a first side of the separator blade, and a second area of the powder print bed located on a second side of the separator blade.

15. The build box according to claim 9 , wherein the information relating to the one or more printed parts includes one or more of a part identification, a part location in the powder print bed, a part model information, a part material composition state, a non-part material composition, a part position or orientation in the powder print bed, a powder bed density, a part quantity, a packed density, a current processing, a next subsystem processing step, a previous subsystem processing step, a beginning to end process flow, a failure status, a temperature profile, or a pressure profile.

16. The build box according to claim 11 , wherein the information relating to the one or more printed parts is accessible both when the build box directly is coupled to the at least one subsystem of the additive manufacturing system and when the build box is not directly coupled to the at least one subsystem of the additive manufacturing system.

17. The build box according to claim 11 , further comprising:
one or more sensors configured to detect at least some of the information relating to the one or more printed parts and to communicate the information relating to the one or more printed parts to a memory.
