Techniques for depowdering additively fabricated parts through fluid immersion and related systems and methods

A method of depowdering additively fabricated parts, the method comprising:

• arranging a plurality of additively fabricated parts within a container containing a liquid, the container coupled to at least one inlet through which the liquid flows into the container, and the container coupled to at least one outlet through which the liquid flows out of the container, wherein each of the plurality of additively fabricated parts is formed from particles of a metal powder held together by one or more binders, and has unbound particles of the metal powder on its surface;
• operating one or more gas jets to jet a gas into the liquid in the container, thereby dislodging at least some of the unbound particles of the metal powder from surfaces of the plurality of additively fabricated parts;
• conveying, by liquid currents within the liquid, unbound metal powder away from the plurality of additively fabricated parts;
• and
• filtering, using a filtration device coupled to the at least one outlet of the container, at least some particles of the conveyed unbound metal powder from the liquid that flows out of the container.
