Abstract

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.
