This paper describes a rapid prototyping method using multiple materials. Because of a capability of utilizing wide range of materials, a rapid prototyping system based on fused deposition modeling using extrusion by screws and cylinders was designed and made. The system has multiple sets of screw and cylinder, each of which contains different materials. The system selects the screw-cylinder during fabrication process so that it can fabricate a solid object consisting of multiple materials. When fabricating an object consisting of multiple materials, bonding between two materials at the boundary is not strong enough in some material combination. To strengthen the bonding, path overlapping method for neighboring two materials in the same layer and path interlace method for two layers of different materials were proposed. By fabricating objects consisting of multiple materials such as polypropylene, elastomer and conductive resin, efficacy, possibility and current limitation of this study are examined.
