  • Publication number: 20080138513
    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).

  • Publication number: 20080134965
    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 corresponding to the object is provided. The device comprises a building field, in which the solidification of the material in powder form takes place; an application element (61), that applies the building material in powder form in the form of a layer; and a drive mechanism (59) that moves the application element (61) across the building field in order to apply the layer of the building material. The drive mechanism (59) is configured such that for the application of layers it moves the application element (61) between a first end position on a first side of the building field and a second end position on an opposite second side of the building field on a circular path back and forth.

  • Publication number: 20080131540
    Abstract: A device (1) for manufacturing a three-dimensional object by a layerwise solidification of a building material at positions in the respective layers that correspond to the object is provided. The device comprises a machine frame (2, 3, 4, 5) and a building space (10) that is arranged in the machine frame. In the building space (10) there are arranged: an application device (27) that applies layers of the building material onto a support device (26) and a previously applied layer, respectively, by an application element (61); a dosage device (28, 29) that provides building material for the application device (27) for an application, and a heating device (31) for heating the applied layers of the building material. The application element (61) and/or the dosage device (28, 29) and/or the heating device (31) are removable from the building space (10) without a tool.

  • Publication number: 20080131541
    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. The device comprises a machine frame (2, 3, 4, 5); a door (73) that is mounted at the machine frame and is swiveling between an open position and a closed position; a container (25) that can be removed from the device; and a support device (26) that is vertically movable in the container and has an upper side, which forms a building platform (78) on which the three-dimensional object is generated layer wise. A mounting (74) for the container (25) is provided at the door (73) and an attachment (75) is provided at the container (25), which attachment can be brought into an engagement with the mounting (74), so that the container (25) can be moved into the device (1) by closing the door (73) and/or can be moved out of the device by opening the door (73).

  • Publication number: 20070298182
    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.

  • Publication number: 20070196561
    Abstract: Provision is made of an apparatus and a method for the manufacture of three-dimensional objects (3) by local solidification of layers of a building material at positions corresponding to the respective cross-section of the object (3), by exposure to electromagnetic or particle radiation. The apparatus comprises a temperature measuring assembly (13) for non-contact measurement of the temperature of the building material in a measurement region (14) which is a partial region of the layer of the building material, and comprises further a position adjustment device (15) for altering the position of the measurement region (14) of the temperature measuring assembly (13) independently of the alteration of the position of the region exposed to the radiation energy. This apparatus can be used to actively access a not exposed region of the surface for measuring the temperature of each layer and to detect a temperature distribution by altering the position of a measurement region (14) in a layer.
