| Abstract Scope |
This work presents a hybrid approach that combines rapid prototyping with reaction injection molding to enable localized, scalable manufacturing. The method uses additively manufactured molds and low-pressure thermoset processing to reduce tooling cost, lead time, and reliance on overseas production. Compared to traditional workflows, the approach minimizes upfront capital requirements while maintaining repeatability, surface finish, and mechanical performance. Experimental use cases demonstrate rapid transition from design to functional parts within a single day, with reduced post-processing and the ability to scale output by increasing mold count or parallelizing systems. The process supports rigid and flexible materials, including fiber-reinforced variants, and enables short-run production, custom manufacturing, and inventory-on-demand. Results indicate a viable pathway for bridging prototyping and production, allowing small teams and manufacturers to achieve cost-competitive, local fabrication without large-scale industrial infrastructure. |
