A metering device serves as an equipping or retrofitting kit for a device for producing a three-dimensional object by means of solidifying, layer by layer, a building material in powder form at those positions that correspond to the cross-section of the object to be produced in the respective layer. The metering device has a metering element, which metering element is rotatable about an axis, preferably an axis of its own, particularly preferably about an, in particular its own, longitudinal axis and which is suitable for dispensing the building material in powder form in a metered manner. The metering element is designed to dispense locally different amounts of powder along the direction of the axis.

Metering device, device and method for additively producing a three-dimensional object

A method of manufacturing an object comprises applying a layer of building material in powder form having a predetermined thickness onto a layer of the building material already previously applied which has been solidified in a region corresponding to a cross section of the object. A recoater is moved in a direction across the layer already previously applied, and the building material is solidified in a shape corresponding to a cross section of the object. Prior to the application of a layer, for a solidified region having a thickness in the layer applied before, the maximum of the product of the extension of this region in movement direction of the recoater and the thickness is determined and during the application of the layer, at least an additional powder amount proportional to the value of the maximum is additionally provided.

Method and device for metering building material in a generative production method

A method of manufacturing a three-dimensional object by a layer-by-layer application and selective solidification of a building material by exposure to a radiation. A hollow body is arranged in a process chamber above a build area which hollow body substantially extends from the build area in a direction of an upper side of the wall of the process chamber. Gas is supplied to the process chamber in such a manner and gas is discharged from the process chamber in such a manner that a lower pressure exists in the region of the process chamber lying within the hollow body than in the region of the process chamber lying outside the hollow body.

Method and apparatus for manufacturing a three-dimensional object

After the manufacturing of an object by layer-wise solidification from a powder, this object is displaced into a container together with the powder surrounding the object, and is closed by a plate, which is positioned below the object during the manufacturing of the object.

Device for the production of a three-dimensional object in layers

The present invention relates to a device for generatively manufacturing a three-dimensional object (), comprising: a frame () defining a building field () at an upper portion () thereof; a plate () which connects the frame () with a housing () of the device; a support () which is arranged in the frame () and vertically movable by a lift mechanics () at least below the building field (); a radiation device () which generates an energetic beam (') which is focused by a deflection means () to arbitrary points in the building field (), so as to selectively sinter or melt a powdery material () which is present in the building field (); a coater () for applying a layer of powdery material () onto the support () or a previously applied layer of the powdery material (). A thermal insulation () is arranged between the frame () and the plate.
