FIELD: process engineering.
SUBSTANCE: invention discloses the layer-by-layer production of 3D object (11) with the help of stereolithographic machine (1). The latter comprises container (2) with fluid to be hardened by preset definite radiation (4a), irradiator (4) of said radiation (4a) that doubles as a hardening device of fluid ply (3) abutting on container (2) bottom (2a). Note here that said machine comprises also the model platform (5) to support hardened ply (6) coupled with drive (7) to displace said platform perpendicular to container (2) bottom (2a), and levelling device (8) to be brought in contact with fluid (3). Proposed process includes the steps that follow. Fluid ply (3) is selectively irradiated to get hardened ply (6). The latter is withdrawn from fluid (3) to redistribute the latter in container (2) by displacement of levelling device (8) so that it passes between model platform (5) and container (2).
EFFECT: accelerated layer-by-layer hardening of fluid.
