Electron Beam Melting (EBM®)

  • Electrons are emitted from a filament which is heated to > 2500°C

  • The electrons are accelerated through the anode to half the speed of light

  • A magnetic field lens brings the beam into focus

  • Another magnetic field controls the movement of the beam

  • When the electrons hit the powder kinetic energy is transformed to heat.

  • The heat melts the metal powder
