    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 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.
