Abstract

Method for additively manufacturing three-dimensional objects (1) based on build data, in particular via successive layerwise selective irradiation and consolidation of layers of a build material which can be consolidated by means of an energy source, which build data define at least one part of an object (1) to be built in the additive manufacturing process, in particular a geometrical structure of the object (1), wherein build data are generated comprising at least two sub-data sets (3, 4) relating to different geometrical parts of the object (1); at least one sub-data set (3, 4) is defined as open sub-data set (4); all sub-data sets (3) except the at least one open sub-data set (4) are locked, wherein the locked sub-data sets (3) are unchangeable and the at least one open sub-data set (4) is changeable; and at least one three-dimensional object (1) is additively manufactured based on the build data.
