When globalization of the production advances, the competition between companies becomes more intense, and the new product development competition intensifies accordingly. Therefore, in the current development of products, it is necessary to perform enough confirmation for the development product by making a prototype in short-term development to an attendant. Therefore technique called, Rapid Prototyping(RP) appeared in trial product molding methods. When there is an overhang in a model shape, support materials are necessary when laminated construction is molded with Fused Deposition Modeling(FDM) which is one of this technique. However, molding time and a material cost are wasted because the support materials are discarded after model molding. In this paper, it is suggested that an overhang is laminated without using support by using 5-axis control device with a turn-tilt table. In addition, it is clarified the angle of inclination of the overhang to need support by the laminating of the evaluation model that the angle of inclination is 60 degrees, and showed the contracted result of the molding time reduced 60% off. And there is a problem in the development and suggested the solution for it.
