Abstract: Systems and methods for additive layer manufacturing of metallic components, such as rocket engines and propellant supply systems, are provided. Methods include melting the surface of a work piece to form a weld pool; adding wire to the weld pool and moving a heat source relative to the work piece to progressively form a new layer of metallic material on the work piece; cooling the formed layer; stress relieving (e.g., peening) the cooled layer; applying a secondary operations either sequentially or simultaneously; and repeating the above steps as required to form components layer by layer. Systems and methods of supplying a first propellant to the rocket engine of a launch vehicle are also provided, where the first propellant is supplied through a heat exchanger for generating mechanical energy to pump the first propellant into the rocket engine, and electrical energy to pump a second propellant into the rocket engine.

Abstract: The present disclosure provides methods and systems for three-dimensional (3D) printing. In an example, a system and method for maintaining a command history in 3D printing software is disclosed. In an example, a method for updating a plurality of printing instructions comprises maintaining a plurality of printing states corresponding to the plurality of printing instructions, wherein a first state corresponds to a first set of printing instructions for printing a first portion of a 3D object. The plurality of printing states may comprise a final state comprising final printing instructions. User instructions may be received to select a second state that is not the final state. A new state may be generated comprising a second set of printing instructions for printing second portion of the 3D object. The plurality of printing instructions may be updated with the second set of printing instructions to yield an updated plurality of printing instructions.

Abstract: The present disclosure provides a system for printing a three-dimensional object. The system may comprise a support for holding a portion of the object and a wire(s) source configured to hold a wire(s) of substantially the same or different diameters. The system may also comprise a print head. The print head may comprise a guide for directing the wire to the support. The system may also comprise a driver roller comprising a groove configured to contact a portion of the wire and direct the wire to the guide, and a power source in electrical communication with the wire and the support. The system may also comprise a controller configured to direct the power source to supply electrical current to the wire and the support. The electrical current may be sufficient to melt the wire when the wire is in contact with the support or the portion of the object.

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.

Abstract: Disclosed herein are systems and methods for using printing process data to predict quality measures for three-dimensional (3D) printed objects and properties of the materials comprising the 3D objects. Printing may be performed using resistive or Joule printing. The system may include a computer communicatively coupled to a 3D printing apparatus, which may store printing parameters. The 3D printing apparatus may be able to take measurements during a print job, and record those measurements in memory. The 3D printing apparatus may also be able to record printing states before, during, and/or after printing. A combination of printing states, printing parameters, and measurements may be analyzed, for example, by a machine learning algorithm, in order to predict material properties and quality measures.
