To expand the contested logistics demonstration and prototyping program to include commercial additive manufacturing facilities in contested logistics environments, and for other purposes.

HR 5190 expands a military logistics program to include commercial 3D printing facilities, allowing them to produce replacement parts rapidly near conflict zones. The bill modifies an existing Defense Department program (Section 842 of the 2024 National Defense Authorization Act) to add "commercial additive manufacturing facilities" as eligible participants for prototyping parts. This change directly affects private manufacturers with 3D printing capabilities, enabling them to support military supply chains in contested areas. The program will operate until December 31, 2030, as specified by the bill's amendment.
