Abstract
A flow device serves for a 3D printer. The device includes a gas conveying device for generating a gas stream and a process chamber with a build area for building the object. The process chamber includes a first gas inlet for introducing a gas stream into the process chamber, and a first gas outlet and a second gas outlet for discharging the gas stream. The first gas outlet is arranged closer to the build area than the second gas outlet in a direction perpendicular to the build area, and the first gas outlet is provided substantially within a lower third of a distance of the build area from a process chamber ceiling a first height range of the process chamber with respect to its extension in a direction perpendicular to the build area and the second gas outlet is provided substantially within the upper four fifths of the distance of the build area from the process chamber ceiling.
