1. A method of additively manufacturing a three-dimensional component by a laser melting process, the method comprising:
selectively solidifying sequential layers of a powdered build material with radiation from a radiation source comprising an energy influx, the energy influx having a point shape and/or a line-shape, the radiation causing a melt region within a build plane defined by the powdered build material, the melt region solidifying to form a three-dimensional component;
capturing sensor values from the melt region using a sensor device;
generating a component quality output based at least in part on the sensor values; and
evaluating a quality of the three-dimensional component based at least in part on the component quality output, the component quality output being used to accept, reject, or modify the three-dimensional component.
