Expansion of the capability of SEBM
Commercial available EBSM machines show strong limitations with respect to the beam power, beam quality and beam control. To overcome these limitations, the electron gun and control system of an Arcam S12 System was renewed. The resulting machine is equipped with a 6 kW electron beam gun and a backscattering electron detector for process monitoring. This is the first electron beam AM machine where the electron beam serves for both, processing and analyzing.
