METHOD FOR FORMING STEREOSCOPIC MODEL USING COMPOSITION CONTAINING CORE SHELL POLYMER

摘要

PURPOSE: To form a three-dimensional object by a method wherein after a part of a photohardenable liq. layer with a specified compsn. is cured by irradiating it with an active radiation, a new photohardenable liq. layer is laminated thereon and this laminate is irradiated with the active radiation. CONSTITUTION: An ethylenic unsatd. monomer, a photoinitiator and a radiation deflecting matter are compounded to obtain a photohardenable liq. compsn. The above described radiation deflecting matter is a core-shell polymer with a core/shell ratio and the first refractive index and the remaining part of the above described compsn. has the second refractive index and the absolute value of the difference in the first and the second refractive indices is not 0. After the above described photohardenable liq. layer is irradiated with an active radiation and at least part of the layer is cured, a new layer of the photohardenable liq. is provided thereon. Then, this layer is irradiated with the active radiation to integrate them by curing at least a part of the layer and an integral three-dimensional object is thereby formed.
