Method for additively manufacturing three-dimensional objects, whereby flow of an inert process gas, preferably an inert gas or containing inert gas, is created, the inert process gas flowing through a chamber () of at least one build apparatus () which is configured to additively manufacture three-dimensional objects by means of successive layerwise selective irradiation and consolidation of layers of a powdered build material () which can be consolidated by means of an energy beam, and/or through a chamber of at least one apparatus () which is configured to perform at least one pre-processing step of an additive manufacturing process, and/or through a chamber of at least one at least one apparatus () which is configured to perform at least one post-processing step of an additive manufacturing process, wherein the flow of process gas displaces a certain volume of fluid from the chamber ().
