The irradiation control model may be configured to determine the irradiation setting based at least in part on a power density factor and/or an irradiation vector factor. The irradiation control command may be configured to change one or more irradiation parameters for additively manufacturing a three-dimensional object. An additive manufacturing system may include an energy beam system and a control system that includes an irradiation controller. The irradiation controller may include a control module configured to perform such a method.

摘要： The invention relates to a method for producing a three-dimensional component by an electron-beam, laser-sintering or laser-melting process, in which the component is created by successively solidifying predetermined portions of individual layers of building material that can be solidified by being exposed to the effect of an electron-beam or laser-beam source (2) by melting on the building material, wherein thermographic data records are recorded during the production of the layers, respectively characterizing a temperature profile of at least certain portions of the respective layer, and the irradiation of the layers takes place by means of an electron beam or laser beam (3), which is controlled on the basis of the recorded thermographic data records in such a way that a largely homogeneous temperature profile is produced, wherein, to irradiate an upper layer, a focal point (4) of the electron beam or laser beam (3) is guided along a scanning path (17), which is chosen on the basis of the data record characterizing the temperature profile of at least certain portions of the layer lying directly thereunder or on the basis of the data records characterizing the temperature profiles of at least certain portions of the layers lying thereunder.
