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;
inserting the build box into a cavity of a depowdering device;
mechanically coupling the build box to a mechanical vibrator of the depowdering device; and
operating the mechanical vibrator to vibrate the build box, causing at least some of the powder to escape the build box through one or more openings in one or more sidewalls of the build box.
