Abstract:
1. A device for manufacturing a three-dimensional object by a layer-wise solidification of a building material in powder form at the positions in the respective layers that correspond to the object, comprising: a container that is arranged in the device; a support device that can be moved vertically in the container, wherein an upper side of the support device forms a building platform, on which the three dimensional object is generated layer-wise; an application device for applying the building material in powder form onto the building platform and a previously solidified layer, respectively, wherein said application device can be moved over said building platform and said previously solidified layer, respectively in a horizontal direction; and an energy source providing a beam for solidifying the building material in powder form; wherein outlets are provided in the device in a region under the container and a directed flow of a fluid medium escapes from each of the outlets, which directed flow is directed to peripheral regions of the container, wherein the container has an angular shape with corners and under each of the corners of the container at least one outlet is provided, and wherein said directed flow of a fluid medium is directed only to the outside corners of the container in an unimpeded path.
