    摘要： A method for the lithography-based additive manufacture of three-dimensional molded bodies, in which a build platform is positioned at a distance from a material support, which is permeable to the radiation of a radiation source at least in some areas, for a material solidifiable by exposure to said radiation, wherein the material support is translationally moved between a first position and a second position, characterized in that material is applied with a defined layer thickness during the movement of the material support from the first position to the second position, after this the applied material, between the build platform and the material support, is location- and/or time-selectively irradiated by the radiation source and solidified, and subsequently material is removed from the material support during the movement of the material support from the second position to the first position.

    摘要： A method of manufacturing an object by stereolithographic 3D printing, wherein the object is built on a building platform layer-by-layer to obtain a stack of structured layers, wherein each structured layer is obtained by curing a photosensitive resin according to a desired pattern, wherein a film of removable material being different from the photosensitive resin is arranged between two adjoining layers, wherein in a post-processing step said film of removable material is subjected to a physical and/or chemical process that causes the first film of removable material to disintegrate or lose its stability and the removable material is removed from the object.

    摘要： A resin composition for three dimensional printing at elevated temperatures forming high temperature-resistant materials, the resin composition comprising a heat curable component A having one or more chemical species chosen from the group comprised of monomers and/or oligomers and/or prepolymers of maleimide derivatives according to formula and a light-curable component B having one or more chemical species chosen from the group comprised of (meth)acrylate, (meth)acrylamide, vinyl esters, vinyl ether, vinyl, allyl, alkinyl or styrenic compounds as well as derivatives thereof substituted with at least one molecule from the group from which component A is chosen, wherein the amount of component A ranges from 30 wt % to 95 wt % based on the total weight of components A and B and the amount of the light-curable component B ranges from 5 to 70 wt %, based on the total weight of components A and B.
