Abstract: A subrack assembly (1) comprising a subrack (3) comprising two top rails (9), two bottom rails (7) and side elements (5), at least one rigidifying frame (21) comprising a front crossbeam, a rear crossbeam and two side beams; and at least one connector (70) for connecting the rigidifying frame (21) to the top and/or bottom of the subrack (3), comprising at least one movable block movable in translation relative to the rigidifying frame (21) between an insertion position, in which it is spaced away from the subrack (3) and a use position, in which it bears against the subrack (3). The connector (70) is configured for connecting the rigidifying frame (21) to the top and/or bottom of the subrack (3) such that the front and rear crossbeams each extend substantially parallel to a top or bottom rail (7, 9) of the subrack (3) and in alignment therewith along a vertical direction.

Abstract: 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).

Abstract: A device (1) for manufacturing a three-dimensional object by a layer wise solidification of a building material at positions in the respective layers that correspond to the object is provided. A feed (96) that supplies the building material to a building space (10) in the device (1) and at least two filler portions (98a, 98b) that are provided at the feed (96) and are independent from one another are provided, wherein one connector (99a, 99b) is provided for each building material supply container (100a, 100b) in order to supply the building material from outside of the device (1).

Abstract: A device (51) for applying layers or a powder material (71) by means of an application device (52) is described, wherein the application device (52) can be moved back and forth between two end positions in order to apply a layer of material (71) and the application device (52) comprises a blade (56) for removing excess material during the application of a layer of material (71). The device (51) is characterized by a material transport device (53), by which the material can be transferred from one side of the blade (56) to the other side of the blade. The device has the particular advantage that layers of material (71) can be applied without any loss of material and is particularly applicable in a laser sintering device.
