摘要： A method for a layer-wise manufacturing of a three-dimensional object has a first step of providing a layer of a material in powder form or a liquid material on a support or a layer that has already been solidified at selected positions previously and a second step of directing a focussed photon or particle beam (8′) selectively at selected positions of the layer. In the second step, the photon or particle beam is selected such that it brings about a change of the absorption of the material when hitting the layer. After the termination of the second step, a third step is carried out, in which the layer is irradiated by means of electromagnetic radiation (18′) such that the material is homogenously solidified at those positions of the layer that correspond to the cross-section of the object to be formed.

摘要： Identification of powders that can be used as construction materials in a layer manufacturing method, comprises mixing the powder with at least one salt of a rare-earth metal, where the salt has the property of exhibiting luminescence when bombarded with photons having a wavelength outside of the visible spectrum or with particle radiation. An independent claim is included for use of the method for coding information regarding the powder composition, preferably regarding the powder-manufacturer or -processor, or the production site of the powder.

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).

摘要： A method for applying powder onto a substrate, e.g. to produce three dimensional items secured by laser sintering, has a reciprocating scraper (8) to move excess powder to collecting systems (11) each side of the substrate holder. The item is built up in layers and the collected powder is recycled to the other side of the scraper while the dosing rate is adjusted to ensure an even coating. The powder is pre-warmed during dosing and is subsequently heated to the process temperature. The recycling means comprise two rotating cylinders rotating in opposite directions.

摘要： A device (1) for manufacturing a three-dimensional object by a layerwise solidification of a building material at positions in the respective layers corresponding to the object is provided. The device comprises a machine frame (2, 3, 4, 5) and a building space (10) located in said machine frame, wherein 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 solidified layer, respectively, by means of an application element (61); a dosage device (28, 29) that supplies building material from a building material accommodation region (23, 24) to the application device (27) for an application; and a heating device (31) for heating the applied layers of the building material. The building material accommodation region (23, 24) is limited by a wall that has a double-wall structure, so that a hollow space (34, 35) is formed therein.

摘要： The device for producing three dimensional objects by layer-wise hardening of constituent at a point corresponding to the object, comprises a working field in which hardening of the constituent takes place, a coating element (61) that applies the constituent in the form of a layer and a drive mechanism (59) having a pneumatic system (69). The coating element is formed as blade, whose side turned to the working field applies the constituent on a carrier device. The drive mechanism forwardly and backwardly moves the coating element on a circular path. The device for producing three dimensional objects by layer-wise hardening of constituent at a point corresponding to the object, comprises a working field in which hardening of the constituent takes place, a coating element (61) that applies the constituent in form of a layer and a drive mechanism (59) having a pneumatic system (69). The coating element is formed as blade, whose side turned to the working field applies the constituent on a carrier device. The drive mechanism forwardly and backwardly moves the coating element between a first end position on a first side of the field and a second end position on oppositely-lying second side of the field on a circular path. The first end position and the second end position have a circular cross-section between them. The drive mechanism has a drive shaft, which is arranged perpendicularly and laterally to the working field and moves over a limited angle region in rotation for producing the movement of the coating element. The coating element extends parallely to the working field and is fastened at the drive shaft in torque proof manner. The pneumatic system moves the coating element by the admission of pressure.
