Yasuhiro Nishikawa, Yujiro Abo
The design and fabrication of materials and products with ink-jet type 3D rapid prototyping was discussed in this paper. At first, the tensile properties of two kinds of UV light-curing resins, which were used as a reinforcement and matrix of composite materials, were evaluated. Secondly, the unidirectional reinforcement composite materials were fabricated. The tensile modulus and tensile strength of the composite material with the 40% reinforcement volume fraction were about 67% and 62% higher than those of the matrix resin, respectively. Based on all experimental results, the nonlinear spring was fabricated using the two-color molding technique.
