Abstract
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.
