Disclosed are a device and a method for producing three-dimensional objects (3) by locally solidifying layers of a structural material at the points corresponding to the respective cross-section of the object (3) under the effect of electromagnetic or corpuscular radiation. The inventive device comprises a temperature measuring apparatus (13) for the contactless measurement of the temperature of the structural material in a measuring area (14) that is a subarea of the layer of the structural material as well as a position adjusting mechanism (15) for modifying the position of the measuring area (14) of the temperature measuring apparatus (13) regardless of the change in position of the zone upon which the radiant energy acts. Said device allows a non-illuminated area of the surface to be actively triggered for measuring the temperature of each layer while making it possible to detect a temperature distribution by modifying the position of the measuring area (14) in a layer.
