Abstract:
Disclosed is a method of providing control data for an additive manufacturing device. The method includes accessing computer-based model data of at least a portion of the object to be manufactured, generating at least one data model of a region of a building material layer to be selectively solidified for manufacturing the at least one object portion. The data model specifies solidification of the building material, and the end point of the at least one solidification path a set of energy introduction parameter values is specified which generates a reference value for the radiation power per unit area in the radiation impact area of the beam bundle on the building material which is lower than the reference value for the radiation power per unit area at other locations of the solidification path, and providing control data corresponding to the generated at least one data model for generating a control data set for the additive manufacturing device.
