Systems, devices, and methods for additive manufacturing

An apparatus for forming and de-powdering one or more parts formed by additive manufacturing, the apparatus comprising:

• a de-powdering system configured to receive a build plate for additive manufacturing, wherein the de-powdering system is configured for use as a build box in a powder bed additive manufacturing system;
• one or more apertures extending through at least one side of the de-powdering system;
• and
• at least one panel movably coupled to the de-powdering system, wherein the at least one panel is configured to move between at least a first position and a second position,
• wherein in the first position, the at least one panel extends along an exterior of the de-powdering system and blocks the one or more apertures,
• wherein in the second position, the at least one panel exposes the one or more apertures, and
• wherein the de-powdering system is transportable from the powder bed fabrication system to another location for de-powdering.

A method for forming and de-powdering at least one part by additive manufacturing, the method comprising:

• delivering a powder material and a binder material to a build plate to form at least one part, wherein the build plate is positioned within a de-powdering structure that includes one or more panels that are at least partially aligned with a plurality of apertures extending through a portion of the de-powdering structure, and wherein the build plate and de-powdering structure are arranged within a powder bed additive manufacturing system;
• removing the de-powdering structure from the additive manufacturing system and transporting the de-powdering structure to another location for de-powdering;
• and
• opening the one or more panels to thereby de-powder the at least one part by removing excess powder material from the at least one part such that the excess powder material passes through the plurality of apertures in the de-powdering structure.
