An apparatus () for additive manufacturing of three-dimensional objects () by successive, selective layer-by-layer exposure and thus successive, selective layer-by-layer solidification of construction material layers of construction material () that can be solidified by means of an energy beam in a process chamber () of the apparatus with a defined process chamber height (H), comprising a flow device () provided for generating an, especially inert, gas flow () flowing through the process chamber () between an inflow section () and an outflow section (), wherein the gas flow () flows through the process chamber () across the entire process chamber height (H), wherein the gas flow () is subdivided into several partial gas flows (-) flowing through the process chamber () parallel on top of each other, which differ in at least one flow parameter affecting the flow characteristics of the respective partial gas flows (-).
