Electron Beam Melting for tungsten components 256

Tungsten components manufacture use Electron Beam Melting (abbreviation EBM) is an additive manufacturing method. Electrons accelerated under vacuum selectively melt metal powder andproduce a 3D component in an additive way layer by layer. The big advantage of this method consists in the energy source used the electron beam. It is used to pre-heat the metal powder and the carrier plate prior to melting, as a result of which deformation and inherent stress are reduced. It is possible to process materials…
