  • Patent number: 11072090
    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.

  • Patent number: 10343301
    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).

  • Patent number: 9358701
    Abstract: A method is described here for the layerwise construction of models, wherein, in a building region, a particulate material is applied layerwise and selectively cured. These steps are repeated until a desired model is obtained. The material comprises in this case a particulate building material and a spray-dried alkali metal silicate solution. Selective activation of the curing proceeds using a water-comprising solution.

  • Patent number: 6861560
    Abstract: A bis-o-aminophenol has a formula I These bis-o-aminophenols permit the preparation of polybenzoxazoles stabilized at high temperatures. The bis-o-aminophenols are preferably prepared from the corresponding diols, which are first nitrosated. The nitroso compound is then reduced to the amino compound by hydrogenation with Pd/C and H2.
