Selective Electron Beam Melting (SEBM) is a powder-based process for additive manufacturing of fully dense metal components. The SEBM-process uses the electron beam as energy source for melting raw material (metal powder). The interaction between metal powder and highly accelerated electrons of the beam results in lattice vibration as well as fusion and vaporizing of the raw material. The large penetration depth (the electrons enter the raw material for several microns) enables the manufacturing of high-melting and / or reflective materials (e.g. Ni-based superalloys with high γ’-content, titanium aluminides, pure copper). Further, the SEBM-process takes place in a vacuum atmosphere, resulting in less contamination of highly reactive materials and better mechanical properties. The electron beam is managed by electromagnetic coils providing accurate and extremely fast beam control.
