1 Arcam Electron Beam Melting (EBM)
11 AArrccaamm EElleeccttrroonn BBeeaamm MMeellttiinngg ((EEBBMM))
In the Arcam EBM®process fully dense metal components are built up, layer-by-
layer of metal powder, melted by a powerful electron beam. Each layer is melted to
the exact geometry defined by a CAD model.
The electron beam is managed by electromagnetic coils providing beam control
that allows several melt pools to be maintained simultaneously.
The vacuum system provides a base pressure throughout the entire build cycle.
During the actual melt process, a partial pressure of helium is introduced to keep a
stable build environment.
For each layer in the build the electron beam heats the entire powder bed to an op-
timal ambient temperature, specific for the material used.
