    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).

    摘要翻译： 本发明涉及一种用于通过多次曝光步骤生成可电磁辐射下可固化的材料（5,55）的成形体（27）的生成方法，特别是用于牙科修复的生坯 （1001,1002,1003,1004），其特征在于，在电磁辐射的作用下可固化的新的材料层（5,55）具有小于或等于电磁辐射穿透深度的一半的层厚度 在曝光步骤（1001,1002,1003,1004）之前提供在可凝固材料（5,55）中，所提供的层仅在曝光步骤（1001,1002,1003,1004）中仅在次要区域（2001 ，3001），并且在其上设置有新层的前一曝光步骤之前设置的层与所述曝光次区域（2001,3001）中的新层一起固化，并且 暴露次区域（2001,3001）i 在曝光步骤（1001,1002,1003,1004）之间变化。
