Abstract
In order to produce a three-dimensional object in a stereolithographic process a plurality of layers (30) are cured in a chronological sequence such that, as a whole, they form the three-dimensional object. The layers are divided into two or more sub-regions (31, 32) which lie substantially adjacent to one another within the layer, wherein one sub-region in an edge area (34) adjoining another sub-region of the same layer contains area parts (35) which protrude into the other sub-region in a form-fitting manner. These sub-regions are developed one after the other and thus together form the desired layer regions.

A method for producing a three-dimensional object (2) in a stereolithographic process, the method comprising:
- developing a plurality of layers (3) in a chronological sequence such that, as a whole, they form the three-dimensional object, wherein at least one of the layers (3, 3a, 3b, 30) is divided into at least two sub-regions, which lie substantially adjacent to one another and are developed in separate development steps,
- wherein each of the sub-regions (21, 22, 31, 32, 41, 42, 51, 52, 61, 62) has a main area and an edge area (23, 34, 43) adjoining another sub-region of the same layer, wherein the edge area contains area parts (35, 36, 53, 63) which protrude into the edge area of the other sub-region in a form-fitting manner.
