A computer-based method of providing control data for an additive manufacturing apparatus for manufacturing a three-dimensional object, wherein by means of the additive manufacturing apparatus the object is manufactured by applying a building material layer by layer and by solidifying the building material by supplying radiant energy to positions in each layer that are assigned to the cross-section of the object in that layer in that by an energy input unit these positions are scanned with at least one energy beam so that energy is input into the building material according to a set of energy input parameters, wherein the method of providing control data comprises: a first step of accessing computer-based model data of at least one portion of the object to be manufactured, a second step of determining a first partial region and a second partial region inside of the at least one object portion, which are abutting each other at a border, a third step of generating at least one data model of a region of a building material layer to be selectively solidified in order to manufacture the at least one object portion, in which a first partial region cross-section intersects the first partial region and a second partial region cross-section intersects the second partial region, wherein it is specified in the data model that in said first partial region cross-section at least one energy input parameter on average has a different value than in said second partial region cross-section and that the at least one energy beam is moved across the border several times while inputting energy into the building material by the at least one energy beam, and a fourth step, in which control data are provided for the generation of a control dataset for the additive manufacturing apparatus, said control data corresponding to the at least one data model generated in the third step, wherein in the third step data models of n+1 consecutive building material layers are generated, n being a natural number, wherein in the data models of n consecutive building material layers a scanning of the building material with the at least one energy beam is specified only in the first partial region cross-section but not in the second partial region cross-section and in the data model of the following (n+1)-th building material layer a scanning of the building material in the first partial region cross-section and in the second partial region cross-section is specified, wherein in the third step the value of at least one energy input parameter is changed inside of a border region, said border region being a region on at least one side of the border in said building material layer described by the data model, the positions to be solidified in said region having a maximum distance of 2000 μm, more preferably 1500 μm, even more preferably 1000 μm, even further preferably 100 μm, most preferably 50 μm, to the border. a first step of accessing computer-based model
