DEVICE AND METHOD FOR BUILDING UP A THREE-DIMENSIONAL OBJECT LAYER BY LAYER |
摘要 |
A device for manufacturing a three-dimensional object by a layer-wise solidification of a building material in powder form at positions in the respective layers corresponding to the object is disclosed. The device comprises: a container (25) arranged in the device; a support device (26), which can be vertically moved in the container, wherein the upper side of the support device (26) forms a building platform (78), on which the three-dimensional object is generated layer-wise; an application device (27) for applying building material in powder form onto the building platform and a previously solidified layer, respectively; and an energy source (6) that provides a beam (9) for solidifying the building material in powder form. In a region below the container (25) in the device (1) outlets (90) are provided, wherein from each of the outlets (90) a directed flow of a fluid medium escapes in a directed manner to peripheral regions of the container (25). |
