Selective Electron Beam Melting (SEBM) is a representative powder bed fusion metal Additive Manufacturing (AM) technique that employs a high-energy electron beam for sintering and melting metal powder bed in a layer-wise fashion. High build temperatures (500 – 1100 oC) and vacuum fabrication environ...
