Additive manufacturing system assessment and control adjustment

A laser additive manufacturing system comprising:

• a laser generator configured to generate a laser;
• a laser movement assembly configured to direct a position of the laser;
• a sensor configured to detect spectral and intensity response information associated with operation of the laser;
• and
• control circuitry configured to:
• control the laser to perform a laser scan of a building surface;
• receive, from the sensor, the spectral and intensity response information captured during the laser scan of the build surface, wherein the spectral and intensity response information is indicative of at least a temperature at the building surface during the laser scan;
• correlate the spectral and intensity response information with spatial positioning of the laser during the laser scan to generate spatially-correlated spectral and intensity response information;
• generate a spatial adjustment mask based on the spatially-correlated spectral and intensity response information and a target spatial intensity profile;
• apply the spatial adjustment mask to spatially-defined laser control parameters;
• and
• control the laser to perform an additive manufacturing build operation to construct a part, the additive manufacturing build operation being performed in accordance with the target spatial intensity profile due to application of the spatial adjustment mask.
