Abstract: Disclosed is a method and device for generating additive manufacturing control data. The control data are generated such that the energy beam has an intensity distribution, at the area of incidence on the build field, in a see tion plane running perpendicularly to the beam axis of the energy beam, which intensity distribution has at least one local minimum in a middle region along at least one secant of the intensity distribution in the section plane and has an intensity profile curve, running along the edge of the intensity distribution, which intensity profile curve has, at least at one point, a maximum value, and, at least at one point in a region opposite the maximum value on the intensity profile curve, a minimum value.

Abstract: Disclosed is a method for regulating an irradiation in a manufacturing process for the additive manufacturing of objects. The method involves identifying shape-regions in object layers to be solidified and categorizing them into reference-regions and correction-regions. Target-temperature maps are created to specify desired heat distribution for the correction-regions. Reference-regions are solidified while recording spatial temperature data, which is used to generate correction factor modules. These modules contain spatially resolved correction factors for irradiation values and are assigned to the corresponding correction-regions. The correction-regions are solidified using their respective correction factor modules, ensuring precise heat distribution and improved solidification accuracy.

Abstract: A method and device for generating control data for an additive manufacturing device are described, wherein build-up material is built up and selectively solidified. Irradiating the build-up material on a build field with at least one energy beam occurs An impingement surface of the energy beam is moved on the build field in order to melt the build-up material in a target area in and around the impingement surface. For generating the control data, optimization criteria and/or secondary and/or boundary conditions relating to a local target temperature distribution in the target area of the build-up material are defined so that melting of the build-up material is effected as heat conduction welding. Based on this, an optimized intensity profile of the energy beam is determined, which is substantially non-rotationally symmetric at the impingement surface on the build field.
