  • The Electron Beam Melting Ebm Process

    Abstract Electron Beam Melting EBM is a metal powder bed fusion PBF process in which the heat source is an electron beam. Di erently from other metal PBF processes, today, EBM is used for mass production. As-built EBM parts are clearly recognisable by their surface roughness, which is, in some cases, one of the major limitations of the EBM process.
