NASA Langley Research Center (LaRC) originated (EBF3) technology development. The Additive Manufacturing Process was primarily developed and engineered by Karen Taminger, material research engineer for NASA LaRC. EBF3 is a NASA-patented additive manufacturing process designed to build near-net-shape parts requiring less raw material and finish machining than traditional manufacturing methods. EBF3 is a process by which NASA plans to build metal parts in zero gravity environments; this layer-additive process uses an electron beam, and a solid wire feedstock to fabricate metallic structures. The process efficiencies of the electron beam and the feedstock make the EBF3 process appropriate for in-space use. Since 2000, a Team of Researchers at the NASA LaRC have led the fundamental research an
