Abstract
Method for additively manufacturing at least one three-dimensional object, whereby a process gas stream streams across the build plane (BP), whereby the process gas stream is adapted to transport respective fume particles from a layer of build material (3) which are generated during selective irradiation and consolidation of the respective layer of build material (3); wherein it is determined that the process gas stream fulfils a pre-definable or pre-defined scheduling criterion; wherein the start time for starting irradiating and consolidating of a first area (A1) and/or the start time for starting irradiating and consolidating the at least one further area (A2, An) is determined on the basis of the determination that the process gas stream has fulfilled the pre-definable or pre-defined scheduling criterion.
