Method and Control Device for Controlling an Irradiation in a Manufacturing Process for the Additive Manufacturing of Objects

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.
