ABSTRACT:
A process of producing a three-dimensionally shaped object comprising a layer forming step of forming a powder material having a refractive index n1into a layer having a prescribed thickness on a support, a cross-sectional shape forming step of binding the layer of the powder material formed in the foregoing step into a prescribed cross-sectional shape with a binding agent having a refractive index n2; and repeating these steps successively, wherein n1and n2satisfy the relationship of −0.1≦(n1−n2)≦0.1.
