Researchers working on this initiative strive to increase the performance and economic competitiveness of materials used in extreme environments and to establish INL as a leader in process innovation and intensification.

INL has successfully deployed this additive manufacturing approach in a test campaign, with more experiments planned.Components for the first water environment test capsules to be used in TREAT were created with additive manufacturing, allowing for complex geometries specially designed for each test11'
