1. 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.
