The broader impact/commercial potential of this SBIR Phase II project is to lower costs for injection molding, a common method of manufacturing plastic goods. Unfortunately, injection molding can be a lengthy and wasteful process because molds are designed, machined from metal, and then shipped to an injection molder. The proposed project will develop new tooling for low-volume injection molding applications at strengths and resolutions comparable with machined aluminum at a fraction of the current cost and lead time, providing extra resilience to the supply chain. This will be used for applications in industries across automotive, aerospace, consumer product goods, and medical devices.This Phase II SBIR will apply advancements in 3D printing of fiber-reinforced photopolymers to the injection molding application. This project will apply advancements in fiber-filled photopolymers (such as ceramic and polymer particle reinforced resins) in combination with magnetically aligned structures to injection mold tools. Tooling inserts will be tested across the most common and challenging injection molding plastics.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该SBIR II期项目的更广泛的影响/商业潜力是降低注射成型成本，这是一种制造塑料产品的常见方法。不幸的是，注射成型可能是一个漫长而浪费的过程，因为设计的模具是从金属加工而来的，然后运送到注射模制器中。拟议的项目将以优势和分辨率与加工铝相媲美的小批量注入成型应用的新工具，其当前成本和交货时间的一部分，为供应链提供了额外的弹性。 这将用于在汽车，航空航天，消费产品和医疗设备的行业中的应用。这II阶段SBIR将在3D打印纤维增强的光聚合物的3D印刷中应用进步。 该项目将在充满纤维填充的光聚合物（例如陶瓷和聚合物颗粒增强树脂）中以及磁对齐的结构与注入模具工具相结合。该奖项将在最常见且具有挑战性的注射成型塑料中进行测试。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，被认为值得通过评估来获得支持。
