Abstract
A method for producing molded parts (), a water-soluble casting mold () being produced in a first step using a layering method, in particular using a powder bed-based layering method. In a second step, the surface of the casting mold () is sealed with the aid of a material (). A casting of the molded part () is then formed by filling the casting mold () with a free-flowing, hardenable material (), in particular a hydraulically setting material. After the casting has solidified, the casting mold () is dissolved with the aid of an aqueous solution (), in particular a heated aqueous solution (). The present application furthermore relates to a material system for producing a water-soluble casting mold (), comprising at least one water-soluble material for building a casting mold () in a layering method, as well as comprising at least one material () for sealing the surface of the casting mold ().
