injection molding rapid tooling? Stereolithography (SL) resins were quickly embraced in the 1980s as the preferred method for obtaining precise and rigid masters for limited-run duplication via silicone tooling.

Following these and subsequent advancements in SL resin technology, these functional materials are used widely not only for silicone tooling, but also for creating functional prototypes for direct application in many R&D processes. One of the most challenging tasks of injection molding rapid tooling facing industry experts today is exploring the applicability of SL materials for direct tooling applications.

Since its inception, the RP industry has traditionally been skeptical, and even slow, to embrace new applications made possible by SL material innovations. Yet direct tooling via stereolithography is now getting a second look, as evidenced by several new commercial applications. While traditional SL resins of the past could not offer the mould life necessary for the effort, the successes of new composite materials [1] are demonstrating new potential for time and cost savings. Success will depend not only on the commercial introduction of these technologically advanced resins, but also on the creation of a network of experts experienced in the design and handling of composite tools.

There are a series of myths surrounding the use of SL resins in many industry areas. One of the primary ones being that companies who focus on high-speed CNC machining will not choose to incorporate SL tools into their production capabilities. This editorial aims to dispel this myth by showing how the two technologies can be successfully combined with injection molding rapid tooling
