Abstract: Systems and methods for providing inert manufacturing and processing environments. In certain embodiments, a build box having green parts that were manufactured via binder jetting additive manufacturing is sealed with a lid and heat cured in an oven. A supply of process gas is delivered to the build box to provide an inert environment within the build box during the heating process, which results in an exhaust of gaseous species from the build box and prevents contamination from the ambient environment. In certain embodiments, copper-alloy parts are manufactured via binder jetting additive manufacturing in an inert environment to achieve higher final densities after post-processing and sintering.

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.

Abstract: 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.

Abstract: Techniques for depowdering in additive fabrication are provided. According to some aspects, techniques are provided that separate powder from additively fabricated parts through liquid immersion of the parts. Motion of the liquid, such as liquid currents, may dislodge or otherwise move powder away from additively fabricated parts to which it is adhered or otherwise proximate to. The liquid may also provide a vehicle to carry away powder from the additively fabricated parts. Removed powder may be filtered or otherwise separated from the liquid to allow recirculation of the liquid to the parts and/or to enable re-use of the powder in subsequent additive fabrication processes. Techniques for depowdering through liquid immersion may be automated, thereby mitigating challenges associated with manual depowdering operations.

Abstract: A method is provided for printing a three-dimensional object. The method comprises, depositing a layer of metal powder onto a powder bed of a three-dimensional printer. A liquid is heated to generate a vapor. The liquid is removed from the vapor to dry the vapor by heating the vapor above a condensation temperature of the liquid. The dry vapor is deposited onto the powder bed of the three-dimensional printer.

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.

Abstract: A system for separating objects within a stacked powder print bed of nested objects comprises a build box configured to contain the powder print bed. The build box has a build box top and a build box floor. The system further includes an elongated aperture formed in a side wall of the build box, and a de-powdering subsystem configured to mechanically and electrically engage the build box. A separating blade associated with the de-powdering subsystem is configured to be inserted through the elongated aperture and into the powder print bed between a top-most print bed layer of the nested objects and a second print bed layer directly below and contiguous with the top-most layer, thereby forming an isolated powder print bed between the separating blade and the build box top. The unbound powder may be agitated by various techniques and subsequently removed from the objects.
