PHOTODETECTOR ARRAY FOR ADDITIVE MANUFACTURING OPERATIONS

摘要

This disclosure describes an additive manufacturing system that includes a build plane having a first region and a second region. Multiple energy source can be positioned above the build plane and configured to direct energy into the first and second regions of the build plane. The system includes optical sensors configured to monitor an intensity of light emitted from the energy sources. A processor associated with the additive manufacturing system is configured to adjust the sensor outputs in response to the energy sources coming into close proximity.
