1. A method for producing a three-dimensional component, the method comprising:
receiving, with a building platform, a powder bed comprising solidifiable building material;
applying, with a powder coating system, a powder layer onto the building platform;
focusing, with a laser radiation source, a laser beam incident upon the powder layer;
guiding, with a scanning device, the laser beam to the powder layer, thereby selectively solidifying the building material;
acquiring, with a thermographic detector, temperature data comprising a temperature profile of one or more layers of the building material, the one or more layers comprising solidified building material;
storing, with a memory of a control device, the temperature data;
controlling, with a processor of the control device, the laser radiation source based at least in part on the temperature data;
determining, based at least in part on the temperature data, a region of local overheating in comparison to a surrounding region, the region of local overheating including a layer of the building material, wherein a next powder layer situated directly above the layer of building material includes at least one portion of the next powder layer within the region of local overheating; and
determining, based at least in part on the temperature data, a scanning path for irradiating the next powder layer so as to initially irradiate the surrounding region with the radiation source prior to irradiating the at least one portion of the next powder layer within the region of local overheating; and
controlling the laser radiation source so as to irradiate the next powder layer according to the scanning path.
