    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: 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 method of computed tomography includes illuminating an object with a cone of illumination, wherein the object is between a source of the cone of illumination and a two-dimensional photo-detector array. The method includes shielding the photodetector array from the collimator shield that includes a slit defined therethrough and moving the slit of the collimator shield across the photodetector array in a direction perpendicular to the slit to expose the photodetector array to the cone of illumination through the slit as the slit scans across the photodetector array to acquire a two-dimensional image of the object. The method includes rotating the object to a new rotational position and repeating movement of the slit to expose the photodetector and rotating the object along the axis until the object has been imaged from multiple rotational positions to form a three-dimensional model of the object.

    Abstract: In accordance with at least one aspect of this disclosure, a fuel injector can include an annular body defining a gas fuel inlet therein, and a structure extending radially outward from the annular body and configured to extend into an air circuit. The structure can include a gas channel defined within the structure at least partially along a radial length of the structure. The gas channel is in fluid communication with the gas fuel inlet where the structure meets the annular body. The structure also includes a slot opening defined at least partially along a radial length of the structure and configured to fluidically connect the gas channel and the air circuit to all gas fuel to effuse into the air circuit.
