Method and device for generative production of a mould with non-planar layers

摘要

The method involves providing a new layer of material solidifiable under an effect of electromagnetic radiation, where thickness of the new layer is less than or equal to half of penetration depth of the electromagnetic radiation into the solidifiable material. The new layer is exposed in subregion of a shaped body layer utilizing an exposure mask, where the body layer is solidified together with the new layer in the exposed subregion. The exposed subregion is varied to produce a shaped body (27). An independent claim is also included for a device for producing a shaped body of a material.
