FIELD: machine building.
SUBSTANCE: group of inventions relates to the stereolithography machine and to the stereolithography machine execution method. Machine comprises: container (2) with the source material (3) defining the limiting it outer surface (4); light emitting device (5) with possibility of the light beam (6) emission; light reflecting device (7) intended for the light beam (6) deflection in the belonging to the outer surface (4) the impact area (8) direction; logical control device (19) intended for the light reflecting device (7) controlling so, that the light beam (6) could selectively fall on the belonging to the impact area (8) working area (10). Machine also comprises the optical device (11) for the light beam (6) focusing on the focal surface (12), where the light beam (6) has the minimum cross section (15). Optical device (11) is located between the light emitting device (5) and the light reflecting device (7), wherein the light emitting device (5) and the optical device (11) are made so, that the maximum diameter of the intersection of the working region (10) with the light beam (6) to the minimum cross-section (15) diameter (wF) ratio does not exceed 1.15. Stereolithography machine execution method includes operations for the light emitting device and the optical device design parameters values selection.
EFFECT: enabling the impact area dimensions selection compared with the known type machines selection.
