PURPOSE:To reduce the effect from the rock or the inclination of the liquid surface of resin by a method in which the first and second radiation means which radiate light beam onto the resin in the vessel which receives the resin cured by at least either one of the lights and heats from mutually different directions are provided, and the energy density at the crossing of the radiated light beams is made equal to the curing energy density of the resin. CONSTITUTION:The light beams 100, 101 radiated from light sources 3a, 3b scan the inside of a vessel 1 by the control of scanner 4a, 4b. Said light beams 100, 101 permeate the resin 2 in the vessel 1, but they are regulated in such degree of energy density that they do not cure the resin 2 in single light path. On one hand, the XY scanners 4a, 4b are controlled by controlling circuit so that the crossing A of said light beams 100, 101 scans the whole part constituting aimed three dimensional model, and cures the resin 2 in the vessel 1, whereby the three dimensional model may be made. Then, the shape and the position at the curing point of the resin 2 are defined by the positional relation and the scanning accuracy of the optical system composed of the light sources 3a, 3b and the XY scanners 4a, 4b. Consequently, the effect due to the rock or the inclination of the liquid-surface of resin may be made difficult to be suffered. |
