Abstract

A method for providing control data for a generative layer construction device includes accessing layer data records that have data models of buildup material layers to be selectively solidified, where a base surface region of an object cross section exists in at least one layer data record, where in at least one of p layers below the base surface region, no solidification of buildup material is specified. The method further includes changing the layer data record such that a temporal sequence for scanning the associated object cross section with energy radiation is specified such that at least one portion of the base surface region is scanned before all other parts of the object cross section; and a third step, where the changed layer data record is provided for the generation of a control data record for the device.
