Publication number: 20200023578Abstract: A method for providing control data for a generative layer construction device has a first step of accessing a data record which, at least for a partial region of an object cross section, specifies in which temporal sequence an energy beam bundle is to be moved in scanning lines over the places of this partial region to scan the buildup material. In a second step, the data record is changed such that in at least one of the layers for the respective partial region of an object cross-section, a check is carried out to determine whether the scan time required to scan the buildup material along a scanning line falls below a predefined minimum duration tmin and either a lower energy density of the energy beam bundle during scanning of the buildup material along this scanning line is specified and/or a wait time is specified before the energy beam bundle is moved along a further scanning line.Type: ApplicationFiled: April 24, 2018Publication date: January 23, 2020Applicant: EOS GmbH Electro Optical SystemsInventors: Sebastian Edelhäuser, Ludger Hümmeler, Peter Hofbauer, Christopher Schmitt
