Abstract

A method for rapidly manufacturing soft tooling from organic polymer-based resins and reinforcement filler materials for use in an injection molding machine to make complex metal and ceramic parts from powders. The cost to produce the tooling is relatively low and the manufacturing time is relatively short compared to conventional processes for making metal tooling. The finished parts are near-net shape, requiring little or no machining, and have excellent sintered properties.
