Abstract
A powder processing machine includes a work bed, a powder deposition device operable to deposit layers of powder in the work bed, an energy beam device operable to emit an energy beam with a variable beam power and scan the energy beam in a path across the powder in the work bed with a variable beam scan rate to melt and fuse regions of the powder, a sensor operable to detect process characteristics in the work bed by location in the work bed during scanning of the energy beam and produce signals representative of the process characteristics and locations, and a controller in communication with the sensor to receive the signals. The controller is configured to identify anomalies in the process characteristics and responsively adjust at least one of the beam power or the beam scan rate at the locations of the anomalies.
