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. The water-soluble material is a material for building the casting mold using a powder bed-based layering method. The sealing material is preferably water insoluble. The material system may also include a free-flowing, hardenable material, which is preferably a hydraulically setting material. The materials of the casting mold are preferably dissolved with the aid of an aqueous solution, and in particular with the aid of a heated aqueous solution.

Material system for producing a molded part using a water-soluble casting mold

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 ().

Process for producing a moulding using a water-soluble casting mould and material system for the production thereof

The invention relates to a biodegradable material made of biological components, comprising 10 to 60 wt. % of a protein adhesive (), which is made of at least one protein, and 2 to 50 wt. % of natural fibers (). Furthermore, 2 to 15 wt. % of at least one hygroscopic mineral (), 10 to 55 wt. % of water (), and 0 to 50 wt. % of an additive component () are provided in the material ().
