The present invention relates to a material system for 3D printing, to a 3D printing process using a lignin-containing component or derivatives thereof or modified lignins, to soluble moldings that are produced by a powder-based additive layer manufacturing process and to the use of the moldings.

3D printing process and molding produced by this process using lignosulfate

A method for producing three-dimensional molded parts by means of layering, the moisture content of the build material mixture being able to be regulated.

Method for producing three-dimensional molded parts and regulating the moisture content in build material

The invention relates to a method for producing 3D components, particulate material being applied in layers to a building platform in a closed build space and printing fluid being selectively applied, and these steps being repeated until a three-dimensional component is obtained, the relative humidity or the relative solvent concentration in the atmosphere in the build space being set to a selected value, and/or the temperature in the build space being set to a selected temperature.

Method and device for 3D printing using temperature-controlled processing

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

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.

Method for the layerwise construction of models

The invention relates to a method for implementing layered construction of plastic models, whereby a first material is applied to a building platform and thereupon a second material is selectively applied and these two application steps are respectively repeated layer after layer until the desired model is obtained. The two materials form a solid body when a suitable mixture ratio is used. The first material includes a particle material and the second material is applied via a print head and contains N-vinylformamide.

Method for the layered construction of plastic models

A bis-o-aminophenol has a formula IThese 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 H.
