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 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 manufacturing includes depositing a first braze material to a first joint location between a first component having a first coefficient of thermal expansion and an intermediate component. The first component is fitted to the intermediate component at room temperature at the first joint location. A second braze material is deposited to a second joint location between the intermediate component and a second component having a second coefficient of thermal expansion. The second component is fitted to the intermediate component at room temperature at the second joint location. The intermediate component has a coefficient of thermal expansion between the first coefficient of thermal expansion and the second coefficient of thermal expansion.

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.
