Abstract: An electrostatic discharge machining fixture includes a fixture body, two or more electrically conductive face contacts seated in the fixture body, and two or more electrically resistive point contacts seated in the fixture body. The electrically conductive face contacts and the electrically resistive point contacts define a 3-2-1 alignment system to locate an additively manufactured article relative to the fixture body during an electrostatic discharge machining operation. Electrostatic discharge machining arrangements and methods of supporting additively manufactured workpieces during electrostatic discharge machining operations are also described.

Abstract: An additive manufacturing build plate system includes a plate body defining a build surface and a rear surface opposite the build surface. A peripheral surface extends between the rear surface and the build surface. At least one gripping feature is defined in the peripheral surface, extending inwardly into the plate body between the build surface and the rear surface.

Abstract: A system can include a torsion applicator (e.g., a torsion motor and shaft) configured to apply a torque to a test article that is additively built on and attached to a build plate. The system can include at least one twist sensor and at least one torque sensor. A method for determining quality of an additively manufactured article or batch thereof can include torsion testing at least one additively manufactured test article that is built on and attached to a build plate while the at least one test article is still attached to the build plate.

Abstract: A method of additive manufacturing includes supplying additive manufacturing powder to a build area of an additive manufacturing machine. The method includes fusing a portion of the powder to form a part, and removing a non-fused portion of the powder from the build area into a removable vessel for storing non-fused powder after building a part. The method can include supplying additive manufacturing powder to a build area, fusing a portion of the powder, and removing a non-fused portion of the powder all on a single discrete lot of additive manufacturing powder without mixing lots.

Abstract: A powder management container includes a keg body having first and second ports. The keg body has an interior for storing a metallic powder. The first port is defined by the keg body and is fluidly coupled to the keg body interior for transferring metallic powder into and from the keg body interior. The second port is defined by the keg body and is fluidly coupled to the keg body interior for controlling the atmosphere within keg body interior. Methods of making powder management containers and managing powder for additive manufacturing techniques are also disclosed.
