America Makes, in partnership with the National Center for Defense Manufacturing and Machining (NCDMM), has announced two project calls totaling $25.6 million, focusing on metal additive manufacturing for defense applications. The $12.4 million Metal Additive Interchangeability Maturity (MIAMI) project aims to validate whether metal additive materials can effectively replace traditional alloys, proceeding in two phases: initial feasibility assessment and process specification development, followed by comprehensive testing. Three awards are expected, with teams required to share validation data. The second project, Integrated In-Situ Testing and Evaluation System (INSITE), funded at $13.2 million, targets a quality assurance framework combining in-situ monitoring and post-build inspection, emphasizing challenges with large components, dense materials, and complex geometries, rather than advancing standalone sensor technologies, to create a certifiable integrated inspection system. Both initiatives support the U.S. Department of Defense’s industrial base strengthening strategy: MIAMI enhances supply chain resilience through material interchangeability, while INSITE boosts overall additive manufacturing reliability via an integrated inspection system. Together, they aim to accelerate the scalable adoption of metal additive technologies in defense, with future focus on material substitution data-sharing mechanisms and online inspection technology integration solutions.
