Abstract
The invention refers to a method of generatively manufacturing a three-dimensional object () in a process chamber () of a generative manufacturing apparatus () by a layer-by-layer application and selective solidification of a building material () within a build area () arranged in the process chamber. In the course of this, while the object is being manufactured, a process gas is supplied to the process chamber by means of a gas supply device and is discharged from the process chamber via an outlet (). According to the invention, the gas supply device is designed and/or arranged relatively to the build area and/or controlled such that a gas stream () of the process gas streaming through the process chamber is shaped in such a manner that a substantially elongate oval impingement area (A) of the gas stream () is generated within the build area ().
