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.

Techniques for depowdering in additive fabrication are provided. According to some aspects, techniques are provided that separate powder from parts by directing gas onto, or near to, the powder. While fragile green parts, such as green parts produced by binder jetting, may be fragile with respect to scraping or impacts, such parts may nonetheless be resistance to damage from directed gas, even if directed at a high pressure. Techniques for depowdering through directed application of gas may be automated, thereby mitigating challenges associated with manual depowdering operations.
