Method of forming transparent 3D object
A method of forming a transparent 3D object and a transparent 3D object formed by the method are provided. A transparent 3D object may be formed as follows. An internal structure of a 3D object is printed using a 3D printer based on a 3D image file having information about an internal region of the 3D object, and a mold, designed to form the 3D object and divided into at least two regions, is printed using the 3D printer based on the 3D image file. Then, the internal structure is combined with an inner region of the mold, and a transparent material is supplied to the mold. After the transparent material hardens, a transparent 3D object is obtained by removing the mold.
