Abstract

See full text

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.
