Abstract
Disclosed is a method of generating a ceiling gas stream in the course of the generative manufacturing of a three-dimensional object in a process chamber by a layer-by-layer application and selective solidification of a building material within a build area arranged in the process chamber. The process chamber has a chamber wall having a process chamber ceiling lying above the build area. A ceiling gas stream of a process gas is passed through the process chamber which is streaming from the process chamber ceiling towards the build area in a controlled manner. In the course of this, the ceiling gas stream is supplied to the process chamber through ceiling inlets formed in the process chamber ceiling such that the ceiling gas stream is directed substantially perpendicularly to the build area downwards onto the build area as it exits the ceiling inlets.
