    摘要： A method and a device for processing a light-polymerizable material (5, 55) for building up an object (27) in layers, using a lithography based generative manufacture having a construction platform (12) for building up the object (27), a projecting exposure unit (10, 60) that can be controlled for locally selected exposing of a surface on the construction platform (12, 62) to an intensity pattern having a prescribed shape, and a control unit (11, 61) prepared for polymerizing overlapping layers (28) on the construction platform (12, 62) in successive exposure steps, each having a prescribed geometry, by controlling the projecting exposure unit (10, 60), in order to thus successively build up the object (27) in the desired shape, said shape resulting from the sequence of layer geometries. The invention is characterized in that a further exposure unit (16, 66) for exposing the surface of the construction platform (12, 62) is provided on the side opposite the projecting exposure unit (10, 60), and that the construction platform (12, 62) is designed to be at least partially transparent to light, and that the control unit (11, 61) is designed for controlling the further exposure unit (16, 66) at least while building up the first layer (28), said layer adhering to the construction platform (12, 62), for exposing in the prescribed geometry.

    摘要： A method and a device for processing light-polymerizable material for the assembly of a mold, utilizing a lithography-based generative manufacturing technique wherein a layer of a light-polymerizable material, the material being located in at least one trough (4) having a particularly light-transmissive, horizontal bottom (6), is polymerized by illumination on at least one horizontal platform (12), the platform having a prespecified geometry and projecting into a trough (4), in an illumination field, wherein the platform (12) is displaced vertically to form a subsequent layer, light-polymerizable material is then added to the most recently formed layer, and repetition of the foregoing steps leads to the layered construction of the mold in the desired form, which arises from the succession of layer geometries. The invention is characterized in that the trough (4) can be shifted horizontally to a supply position, and the supply device (8) brings light-polymerizable material at least to an illumination field of the trough bottom (6), before the at least one trough (4) is shifted to an illumination position in which the illumination field is located below the platform (12) and above the illumination unit (10), and illumination is carried out.
