PURPOSE:To shorten an exposure time, reduce shape inner stress and minimize a deformation of a shape, by a method wherein UV rays are applied again to a model shaped of UV-curing resin by making use of 3D lithography technique from various directions and cured completely. CONSTITUTION:Optically-shaped model 2 is put on a mirror table 4 provided with turning motive power 5. UV rays to be exposed to the optically shaped model 2 through a UV lamp 1 installed on the upper part or an arbitrary position is applied to every nook and corner of the optically shaped model through a reflection mirror 3. Consequently, sufficient exposure to the whole surface of the optically-shaped model becomes possible. On this occasion, more uniform exposure becomes possible by tuning the mirror table 4. |
