Abstract
Techniques for depowdering in additive fabrication are provided. According to some aspects, techniques are provided that separate powder from parts through vibration of the powder, the parts, and/or structures mechanically connected to the powder and/or parts. For instance, the application of vibration may dislodge, aerate and/or otherwise increase the flowability of regions of the powder, thereby making it easier to remove the powder with a suitable means. Techniques for depowdering through vibration may be automated, thereby mitigating challenges associated with manual depowdering operations.
