摘要： In a process for the lithography-based generative production of three-dimensional shaped bodies, wherein material that is solidifiable by exposure to electromagnetic radiation is present on a material support that is permeable in at least a region thereof, a building platform is positioned at a distance from the material support, material located between the building platform and the material support is heated and in the heated state is location-selectively irradiated by a first radiation source and solidified, wherein the electromagnetic radiation is introduced into the material from below through the material support that is at least partially permeable to radiation from the first radiation source, the heating of the material is performed by irradiating the material support with electromagnetic radiation of a second radiation source, wherein the material support is substantially impermeable for the radiation of the second radiation source.

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.
