| description | The invention relates to a method for producing a moulded body by building up layers of powdered material, comprising the steps of: a) preparing a layer of powdered material, b) heating the layer using controlled radiation by irradiating selected points of the layer according to a cross-sectional pattern of the moulded body assigned to said layer according to the geometry description data of the moulded body, so that the powdered material is solidified by melting to form connecting regions according to the cross-sectional pattern of the moulded body, c) preparing a next layer of powdered material on the layer irradiated most recently and d) heating the most recently prepared layer using controlled radiation by radiating selective points of the layer according to a cross-sectional pattern of the moulded body assigned to said layer, so that the powdered material is solidified by melting to form connecting regions according to said cross-sectional pattern of the moulded body, and e) repeating steps c) and d) multiple times at least until the build-up of the moulded body is complete, wherein the energy application to selected points in radiation steps d) can be varied per unit of time by performing the radiation according to the respective radiation point on the powdered layer. |
