Figure 3. Service temperatures and FDM material applications. Figure 2. FDM materials – mechanical properties. trim of cured parts. In the event that the useful temperature range of FDM tooling needs to be expanded, multi-staged cure cycle composite resins provide a viable solution. Multistage resin systems afford users the opportunity to initially cure (B-stage) lay-ups at a lower temperature. At this point, the lay-up is strong enough to be removed from the lay-up tooling and then exposed to the final cure cycle to bring the part up to its final strength and service temperature. To estimate the thermal growth of FDM tools, the CTE of each material must be determined. Testing was conducted at a third party test laboratory, National Institute for Aviation Research (NIAR), per ASTM E228. See Table 1 for results. Rapid: Cycle Time Reduction FDM has demonstrated reduced cycle times based on two primary factors. First, FDM utilizes the CAD model to define and create the desired tooling. This enables the user to directly fabricate the desired tooling without the need for traditional methods that require a series of positive and negative splash molds to generate a final tool. In addition, since the tools are all mastered off of the CAD model, fabrication errors and restarts are minimized. Second, FDM produces the tools in a simplified “lights-out” method. File processing time can be conducted in minutes and then submitted to the FDM system for fabrication. Most tooling that aligns with this application can be fabricated overnight so the tool is ready for use the next day. The ability to rapidly define and fabricate a wide variety of tools from a single system minimizes the long cycle delays that can be experienced with traditional tooling methods. These simplified manufacturing methods allow companies that routinely contracted for tool manufacturing to manufacture their own tools with relatively low overhead. Table 1. FDM CTE properties.
