Abstract
Techniques for depowdering additively fabricated parts are described. The techniques utilize various mechanisms to separate powder from parts. For instance, techniques for depowdering described herein may include fabrication of auxiliary structures in addition to fabrication of parts. Certain auxiliary structures may aid with depowdering operations, and may be fabricated along with parts during an additive fabrication process. The auxiliary structures may be shaped and/or have positional and/or geometrical relationships to the parts during fabrication. For instance, an auxiliary structure may include a cage structure fabricated around one or more parts.
