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 for manufacturing a three-dimensional object by successively solidifying layers of a building material at positions in the respective layer corresponding to the cross-section of the object is provided, wherein at least a partial region of a layer is solidified such that a pattern is generated, which pattern contains a plurality of substantially parallel solidification lines (V, S), and at least a partial region of a subsequent layer is exposed such that a pattern is generated, which pattern contains a plurality of substantially parallel solidification lines (V, S) that are rotated with respect to the solidification lines of the pattern of the previous layer by an angle (&#x3b1;) that differs from 180&#xb0;, 90&#xb0; and 45&#xb0;.
