Electron Beam Patterning System in Additive Manufacturing

A method and an apparatus involve applying a pattern on an addressable patternable cathode unit. The cathode unit is stimulated to emit an electron beam pattern. A patterned image in the electron beam pattern is positioned to a desired position such directly to as a powder bed for additive manufactu...

Zusammenfassung:	A method and an apparatus involve applying a pattern on an addressable patternable cathode unit. The cathode unit is stimulated to emit an electron beam pattern. A patterned image in the electron beam pattern is positioned to a desired position such directly to as a powder bed for additive manufacturing or to an electron beam addressed light valve for controlling spatial patterns on an optical signal for powder bed manufacturing.
