METHOD AND ELECTRON BEAM EQUIPMENT FOR PROCESSING POWDERED MATERIALS AT HIGH ACCELERATION VOLTAGES

Methods for processing a powdered material using electron beam equipment for the additive manufacture of components, which methods solve the problem of electrostatic powder entrainment and significantly reduce the process times. This effect is achieved by acceleration voltages of 90 kV or greater in...

Zusammenfassung:	Methods for processing a powdered material using electron beam equipment for the additive manufacture of components, which methods solve the problem of electrostatic powder entrainment and significantly reduce the process times. This effect is achieved by acceleration voltages of 90 kV or greater in the pre-heating step and/or in the melting step.
