The component is produced by the successive solidification of individual layers of a construction material solidified by the action of radiation, by sintering or fusing the construction material. The fusion region is captured by a sensor device and sensor values for evaluating the quality of the component are derived therefrom. The sensor values with the co-ordinate values which localize the sensor values in the component are stored with a division of the calculated sensor values into values which are critical to the structural quality of the component and non-critical values to said quality and with a representation of those values critical to the structural quality of the component as to their distance from a reference point lying or arranged in the region of the surface.
