Current applications for rapid prototyping(RP) technologies require the availability of materials with high temperature capabilities and mechanical properties approaching the end-use material. A principal RP focus is on facilitating the production of tooling(soft, bridge, an hard) to be used in conjunction with concept, prototype, and production manufacturing. research at the university of Dayton research Institute(UDRI) has developed RP materials and processes to aid in meeting the tooling requirements. One program has lead to the development of materials and processes using monolithic ceramic and ceramic composite(CMC) tapes in the fabrication of ceramic objects by laminated object manufacturing(LOM). Another program has developed a high-temperature photopolymer for stereolithography(SL). The properties of these materials make them suitable for use as idrect tooling and as master models for production of hard tooling by secondary processes.
