Abstract: The invention relates to a 3D printer having an advantageous irradiation device, and a method for 3D printing. The irradiation device is an array of multiple irradiation units each of which is individually controllable with regard to its temperature. According to an embodiment, a subset of irradiation units is combined to a group, each group of irradiation units being controllable with regard to its temperature. The target temperature of the irradiation units at the edges can be set to a temperature that is higher than the target temperature of the irradiation units in the remaining area.
