Abstract:
Disclosed is a method for providing control data for an additive manufacture device having a first step of accessing model data, and a second step of generating a data model in which a construction material layer region to be solidified during the production of an object section is specified for a construction material layer. The region to be solidified is divided into a first sub-region and a second sub-region, and a respective solidification scan of the region locations to be solidified is specified in a data model. The scan solidifying the construction material, and a repeated scan, is specified at the locations of the second sub-region but not at the locations of the first sub-region. The energy input parameter during the repeat scan is measured such that the temperature of the construction material lies above a melting temperature. The method further includes a third step of providing data models generated in the second step as control data for integrating into a control data set.
