摘要： The present invention relates to a method for the generative production of a shaped body (27) of material (5, 55) solidifiable under the effect of electromagnetic radiation, in particular a green compact for dental restoration, by means of a multiplicity of exposure steps (1001, 1002, 1003, 1004), characterized in that a new layer of material (5, 55) solidifiable under the effect of electromagnetic radiation, having a layer thickness which is less than or equal to half the penetration depth of the electromagnetic radiation into the solidifiable material (5, 55), is provided before an exposure step (1001, 1002, 1003, 1004), the layer provided is exposed in the exposure step (1001, 1002, 1003, 1004) only in a subregion (2001, 3001) of the shaped body layer to be formed, and a layer provided before a preceding exposure step, on which the new layer has been provided, being solidified together with the new layer in the exposed subregion (2001, 3001), and the exposed subregion (2001, 3001) is varied between the exposure steps (1001, 1002, 1003, 1004).
