Abstract: A method for producing a three-dimensional object by layer by layer solidifying of a material which is solidifiable under the action of radiation is provided. The method makes use of exposure masks. In order to form each object layer to be solidified of the object in a construction plane, there is generated at least one, preferably a single, digital exposure mask by means of which the radiation is selectively projected into the construction plane. For each exposure mask, according to the object layer to be solidified, a single 2-bit bitmap is calculated which assigns either the bit-value “transparent” or the bit-value “non-transparent” to each pixel of the exposure mask. In addition, an improved exposure mask generating apparatus and an improved device for producing a three-dimensional object are proposed.
