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.

Abstract: A method and a control data generating device (54, 54?) for generating control data (BSD, PSD) for an additive manufacturing device (1) are described, wherein build-up material (13) is built up and selectively solidified. For this purpose, irradiating the build-up material (13) on a build field (8) with at least one energy beam (AL) takes place, wherein an impingement surface (22) of the energy beam (AL) is moved on the build field (8) in order to melt the build-up material (13) in a target area (?Z) in and around the impingement surface (22). For generating the control data (BSD, PSD), optimization criteria (OK) and/or secondary and/or boundary conditions (WB) relating to a local target temperature distribution (TV) in the target area (?Z) of the build-up material (13) are defined so that melting of the build-up material (13) is effected as heat conduction welding.
