Original sentence: EBF3 or Electron Beam Free Form Fabrication, is a process by which NASA hopes to build metal parts without gravity.Electron beam free form fabrication (EBF3) is a layer-additive process that uses an electron beam and wire to fabricate metallic structures.The process efficiencies of the electron beam and the solid wire feedstock make the EBF3 process attractive for use in-space
Edited sentence: EBF3 is a layer-additive process that uses an electron beam and a solid wire feedstock to fabricate metallic structures.EBF3 or Electron Beam Free Form Fabrication, is a process by which NASA hopes to build metal parts in zero gravity environments.The process efficiencies of the electron beam and the feedstock make the EBF3 process attractive for use in-space
