PURPOSE: To add functional properties such as electric conductivity, thermal conductivity, rigidity, toughness, improvement of specific gravity, etc., to an optically shaped body by a method wherein resin in which powder is mixed is used to carry out optical shaping. CONSTITUTION: Ultraviolet beams outputted from an ultraviolet laser 1 are introduced onto a liquid surface of powder-mixed resin by an optical fiber. That is, the ultraviolet beams pass through a pun hole 2 and a shutter 3, passes through a condenser 4 controlled with an NC scanner 15 and converted. Thereafter, the powder-mixed resin stored in a container of which a bottom surface is made of a glass plate is irradiated therewith. The condenser 4 can move a focal point position by the NC scanner 15. The condenser 4 draws a contour of a cubic section on a surface of the resin by X-Y biaxial control, and cured resin is formed on a laminate table 22. Then, operation wherein the laminate table 22 is slightly sinked into liquid, and further irradiated with ultraviolet beams to execute lamination, is repeated a specific number of times, and thereby the cured resin is laminated to prepare a cubic model. |
