Abstract

The invention is a method for producing a three dimensional object in layers through stereolithography comprising the following operations: moving a supporting surface (6a 7a) near the bottom (2a) of a container (2) containing a liquid substance (3) so as to arrange it in a predefined operating position (17); selectively irradiating a layer (6) of liquid substance (3) with predefined radiation (4) in such a way as to solidify it against the supporting surface (6a 7a). The approaching movement (11) comprises a plurality of approaching moves (12 12a 12b 12c) having corresponding predefined lengths (13 13a 13b 13c) spaced by corresponding intermediate stops (14 14a 14b) for corresponding predefined time intervals (15 15a 15b) the intermediate stops (14 14a 14b) being carried out when the supporting surface (6a 7a) is at least partially immersed in the liquid substance (3).
