Abstract

The invention relates to a method for constructing a three-dimensional object () in layers from a pulverulent construction material by solidifying layers of the pulverulent construction material in a successive manner at each layer point which corresponds to a cross-section of the object, wherein the solidification process is carried out by introducing thermal energy. The method has the following step: solidifying all the layer points which correspond to a cross-section of the object. The introduced thermal energy quantity is adjusted at least in a sub-region of the layer dependent on the duration of the previous solidification step for the previous powder layer or dependent on the current solidification step duration, which is calculated in advance.
