  • Publication number: 20250001512
    Abstract: A plasma arc torch assembly is capable of additively manufacturing articles. A device may additively manufacture at least a portion of an article using the plasma arc torch assembly. A device may deactivate at least one plasma arc associated with the plasma arc torch assembly. A device may perform plasma arc surface smoothing of the article using the plasma arc torch assembly.

  • Publication number: 20240375203
    Abstract: Wire buffer systems that can buffer one or more wires are described. The wire buffer system can include a buffer tube. The buffer tube can include entry passages, exit passages, an outer cylinder, and an inner cylinder. The inner cylinder can be fixed in a position coaxial with the outer cylinder. Flexible wire guides can be coupled to the entry passage. The flexible wire guide can extend in a spiral around the inner cylinder and exit the buffer tube through the exit passage. The wire buffer systems can further include measurement systems. The measurement systems can include time-of-flight (TOF) sensors, linear rails, and carriages.

  • Publication number: 20240293887
    Abstract: Cryogenic sources can be used for shielding in wire-based additive manufacturing. Cryogenic shielding can provide better shielding during print, as well as more efficient cooling compared to using regular room temperature shielding gas. Cryogenic shielding can extend the nozzle run time by preventing spatter build up in nozzles. Cryogenic sources also can be used for active part cooling and/or active weld puddle cooling.

  • Publication number: 20240253146
    Abstract: A device may position a torch assembly relative to a workpiece. A device may initiate a pilot arc between a plasma electrode and a grounded portion of a torch assembly, the grounded portion of the torch assembly grounded using a component with a variable resistance. A device may initiate a wire arc between a first wire element and the workpiece. A device may add material to the workpiece while the torch assembly traverses the workpiece.
