Specifications for Scalable Metal Additive Manufacturing System (10.18.2023)To meet the rate of output necessary for project success, ORNL is looking to expand their capabilities in metal laser powder bed additive manufacturing. The system specifications that are required are listed below.
Essential to achieving this goal is the ability to print small metallic parts by using laser deposition methods in combination with a variety of other energy sources. This requires acquiring a compact hybrid manufacturing cell that enables laser deposition of metal powder using powder feeders that supports precision control of small volumes of powder and permits open access to all of the processing data.

This powder can then be used for additive manufacturing feed stock in space, and completing the parts or products by the additive manufacturing in space.Advantages: Metallurgical thermochemical refining during the powder making method is required to produce high quality metal powder from asteroids or meteorites that is suitable for AM processes such as selected laser melting (SLM) powder bed, laser metal deposition (LMD) powder fed, electron beam
In selective laser melting (SLM) or selective laser sintering (SLS), a layer of metal powder is spread across a build area and solidified into a desired pattern using a laser beam that is rastered over the powder surface. Binder jet printing involves spreading a powder layer and selectively applying a polymeric binder using an inkjet-like process.
The atomization system shall be installed at NASA Glenn Research Center, Cleveland Ohio, and shall be capable of melting and atomizing Fe-, Ni-, Co-, and Cu-based alloys and other non-reactive metals with a melt charge capacity of 20 - 50 kg. The resulting powders will be used in additive manufacturing processes, such as direct metal laser sintering, as well as other general powder metal processes.
