Patent ID: 10919219

Abstract:
The invention refers to a method of generatively manufacturing a three-dimensional object (2) in a process chamber (3) of a generative manufacturing apparatus (1) by a layer-by-layer application and selective solidification of a building material (13) within a build area (10) 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 (42a, 42b). 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 (40) of the process gas streaming through the process chamber is shaped in such a manner that a substantially elongate oval impingement area (A3) of the gas stream (40) is generated within the build area (10).
