Abstract

The invention relates to a method for producing micro-structured shaped parts (22) and the resulting products, wherein a first negative or positive photosensitive layer (12) with a layer thickness (D1) is deposited on a substrate (10) and the first negative or positive photosensitive layer (12) is exposed area-by-area with light of a suitable wavelength; a second negative or positive photosensitive layer (12') with a layer thickness (D2) is deposited on the first negative or positive photosensitive layer (12) and exposed area-by-area with light of a suitable wavelength, wherein the exposed regions (16') in the second layer (12') are identical to and/or different from the exposed regions (16) in the first layer (12); the steps of depositing and exposing the photosensitive layer (12, 12') area-by-area are performed repeatedly until a predetermined height H is attained, wherein the exposed regions (16, 16') of the photosensitive layers (12, 12') represent the positive or negative of the microstructure of the shaped part (22); the exposed (16, 16') or the unexposed regions (18, 18') of the shaped part (22) are washed out with a developer; and the remaining preform (20) is subsequently solidified.
