FIELD: machine building.
SUBSTANCE: invention represents three-dimensional object layer by layer making method by means of stereolithography. Method comprises following stages: support surface (6a, 7a) movement close to container (2) bottom (2a), containing liquid substance (3), so, that to provide its placement in certain working position (17); selective exposure of liquid substance (3) layer (6) to certain radiation (4), to ensure its hardening on support surface (6a, 7a). Approaching displacement of support surface (6a, 7a) to bottom by means of coordinate displacement (11, 11'), containing plurality of approaching displacements (12, 12a, 12b, 12c), having corresponding certain lengths (13, 13a, 13b, 13c) and divided by corresponding intermediate stops (14, 14a, 14b) to corresponding certain time intervals (15, 15a, 15b). Intermediate stops (14, 14a, 14b) are performed, when supporting surface (6a, 7a) is, at least, partially immersed into liquid substance (3).
EFFECT: technical result achieved when using method according to invention consists in fact, that in order to limit both compression stress in formed three-dimensional object, and axial loads acting to container bottom or to any glass wall.
