Abstract

An exposure control device serves for equipping and/or retrofitting a generative layer-wise building device. The exposure control device has a first data output interface, at which control commands can be output to the exposure device. The control commands specify one of a plurality of exposure types defined by a predetermined combination of a radiation energy density to be emitted by the exposure device and a scanning pattern with which the radiation is being directed to a region of a layer of the building material. The exposure control device also includes a second data output interface 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.
