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 system for removing powder from an additively manufactured article includes a powder removal mechanism. The powder removal mechanism can include a build plate holder configured to hold a build plate at a distal end thereof. The powder removal mechanism can also include a first actuator that is configured to angle the build plate holder relative to gravity and a second actuator that is configured to rotate the build plate holder about a central axis of the build plate holder.

Abstract: A system comprising an additive manufacturing machine configured to fuse stock powder, a supply vessel connected to the additive manufacturing machine for supplying the stock powder to the additive manufacturing machine, and a weight sensor system connected to the supply vessel. A controller operatively is connected to the weight sensor system configured to receive signals indicative of a weight of the stock powder in the supply vessel. The controller is configured to determine weight of the stock powder based on the signals.

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.

Abstract: A method includes additively manufacturing an article in an inert environment, removing the article from the inert environment and placing the article in a non-inert environment, allowing at least a portion the article to oxidize in the non-inert environment to form an oxidized layer on a surface of the article, and removing the oxidized layer (e.g., to smooth the surface of the article). The method can further include relieving stress in the article (e.g., via heating the article after additive manufacturing).
