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: The present invention relates to a device for manufacturing three-dimensional models by means of a 3D printing process, whereby a build platform for application of build material is provided and a support frame is arranged around the build platform, to which said support frame at least one device for dosing the particulate material and one device for bonding the particulate material is attached via the guiding elements and the support frame is moveable in a Z direction, which essentially means perpendicular to the base surface of the build platform, said movement provided by at least two vertical positioning units on the support frame. In this respect, it is provided that the positioning units are respectively separate components and are arrangeable on the support frame independently from one another and the location and orientation of such can be adjusted independently from one another.

Abstract: The invention relates to methods and devices for constructing models in layers. A region for constructing models, preferably a construction platform, and a material applying device for applying material onto the region are provided. The material applying device is arranged in a movable manner over the region. The material applying device is designed as a portal such that the material applying device can be moved over the region at least via two linear guides arranged at opposite sides of the region, and the material applying device is arranged around the region such that a portal is formed by at least two portions that extend laterally with respect to the region.
