PROBLEM TO BE SOLVED: To provide a prototype by rapid prototyping, excellent in internal visibility and enabling several times of attachment or detachment. SOLUTION: The prototype 1 includes a photofabrication portion 2 and a powder fabrication portion 4 joined thereto, and the portion 18 of the prototype 1 connectively fixed to other members is composed of the powder fabrication portion 4. The powder fabrication portion 4 is arranged so as to surround the whole circumference of the outer periphery of the transparent photofabrication portion 2, and is joined thereto by a structure superposed therewith. According to such a constitution, internal visibility is secured by the transparent photofabrication portion 2 and further, the toughness of the connectively fixed portion 18 to which force is applied when attached or detached is secured by the powder fabrication portion 4 having excellent toughness. Thus, visibility is compatible with durability to attachment or detachment. COPYRIGHT: (C)2009,JPO&INPIT
