Abstract: 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.

Abstract: A method for producing molded parts (16), a water-soluble casting mold (6) 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 (6) is sealed with the aid of a material (9; 10). A casting of the molded part (16) is then formed by filling the casting mold (6) with a free-flowing, hardenable material (13), in particular a hydraulically setting material. After the casting has solidified, the casting mold (6) is dissolved with the aid of an aqueous solution (18), in particular a heated aqueous solution (18). The present application furthermore relates to a material system for producing a water-soluble casting mold (6), comprising at least one water-soluble material for building a casting mold (6) in a layering method, as well as comprising at least one material (9; 10) for sealing the surface of the casting mold (6).

Abstract: The present invention relates to a method for producing three-dimensional objects based on computer-provided data, whereby a material is deposited in layers in a process chamber and the material is selectively solidified and/or bonded using a bonding apparatus and/or a solidifying apparatus in the process chamber, these steps being repeated. A conveyance of the material proceeds during the build process and proceeds continuously, sequentially and evenly up to an unpacking position.
