Zusammenfassung:An exposure control device (31) serves for equipping and/or retrofitting a generative layer-wise building device (1). The latter comprises an exposure device (20) which emits electromagnetic radiation (22) or particle radiation and is configured to irradiate positions to be solidified in a layer in such a way that after cooling they exist as an object cross-section or part of the same. The exposure control device (31) has a first data output interface (36), at which control commands can be output to the exposure device (20). The control commands which are output specify one of a plurality of exposure types wherein an exposure type is defined by a predetermined combination of a radiation energy density to be emitted by the exposure device (20) and a scanning pattern with which the radiation (22) is being directed to a region of a layer of the building material (15). Furthermore, the exposure control device (31) has a second data output interface (37) at which an exposure type can be output in real time in relation to a timing of the output of a control command specifying this exposure type.
