Techniques for depowdering additively fabricated parts through vibratory motion and related systems and methods

A method comprising:

• fabricating, within a build box inserted into an additive fabrication device, one or more additively fabricated parts from a powder by directing at least one binding agent onto regions of successive layers of the powder;
• removing the build box from the additive fabrication device, the build box containing a powder bed comprising the powder and the one or more additively fabricated parts, wherein the build box comprises a build surface over which the powder bed is arranged;
• inserting the build box into a cavity of a depowdering device;
• operating at least one actuator of the depowdering device to raise the build surface, thereby pushing the powder bed upwards and exposing a first section of the powder bed above the build box;
• operating a scraper to move over the build box and thereby push the first section of the powder bed onto an adjacent surface;
• and
• removing surface powder from one or more parts contained within the first section of the powder bed.

At least one non-transitory computer readable medium comprising instructions that, when executed by at least one processor, perform a method comprising:

• operating an additive fabrication device to fabricate, within a build box inserted into an additive fabrication device, one or more additively fabricated parts from a powder by directing at least one binding agent onto regions of successive layers of the powder;
• removing the build box from the additive fabrication device, the build box containing a powder bed comprising the powder and the one or more additively fabricated parts, wherein the build box comprises a build surface over which the powder bed is arranged;
• inserting the build box into a cavity of a depowdering device;
• operating at least one actuator of the depowdering device to raise the build surface, thereby pushing the powder bed upwards and exposing a first section of the powder bed above the build box;
• operating a scraper to move over the build box and thereby push the first section of the powder bed onto an adjacent surface;
• and
• removing surface powder from one or more parts contained within the first section of the powder bed by operating a robotic arm coupled to a source of pressurized gas and/or to a vacuum.
