Abstract
A High Energy Beam Processing (HEBP) system provides feedback signal monitoring and feedback control for the improvement of process repeatability and three-dimensional (3D) printed part quality. Electrons deflected from a substrate in the processing area impinge on a surface of a sensor. The electrons result from the deflection of an electron beam from the substrate. Either one or both of an initial profile of an electron beam and an initial location of the electron beam relative to the substrate are determined based on a feedback electron signal corresponding to the impingement of the electrons on the surface of the sensor. With an appropriate profile and location of the electron beam, the build structure is fabricated on the substrate.
