America Makes
Maturation Initiative for Additive Metals Interchangeability (MIAMI)
Posted Date: April 30, 2026
Proposal Due Date: July 09, 2026
This funding opportunity supports projects that demonstrate material interchangeability by showing how a selected, moderately mature metallic additively manufactured (AM) alloy/process can replace one or multiple legacy alloys in Department of War (DoW) weapon system components. Teams will identify candidate parts and operating conditions, define performance requirements, and generate shared, pedigreed data proving the AM material meets or exceeds the critical properties of the traditional materials it aims to replace. Emphasis is on broad applicability across platforms, reduction of redundant testing, and accelerating qualification to enable drop-in substitution of AM materials for legacy alloys.
The National Center for Defense Manufacturing and Machining (NCDMM) will conduct a competitive proposal process and reserve the right to select one, multiple, or no awards in the topic areas outlined in Section 2. Proposers are welcome to submit multiple proposals. Each proposal is limited to addressing one topic area only. Maximum allowable periods of performance (PoP) are dependent upon which topic area the proposal intends to address. Proposing shorter PoPs than listed are acceptable.
