Abstract

Additive manufacturing systems may include a laser melting apparatus, a sensor device, and a visualization apparatus. A laser melting apparatus may form a three-dimensional component by exposing a powder bed to a beam of radiation based on build coordinates, with the beam of radiation providing an energy influx that generates a melt pool in a melt region of the powder bed. A sensor device may capture sensor values corresponding to the melt pool and/or the melt region. A visualization apparatus may display a representation of the three-dimensional component, with the display including the build coordinates and the sensor values in respect of a capture location thereof in the three-dimensional component. The displayed representation may be based on a display output that includes sensor values correlated with build coordinates.
