Additive manufacturing in Defense is the use of additive manufacturing in military and defense: sustainment parts, expeditionary repair, weapons system components, hypersonic vehicle structures, and tactical UAS production.
Why AM fits Defense: Defense values AM for supply-chain resilience (forward-deployed repair via expeditionary printers), legacy-platform sustainment (parts whose original supplier no longer exists), and high-rate production of attritable systems (loitering munitions, tactical drones). DoD ManTech, NavalX, AFWERX, and DARPA actively fund AM scale-up across all services.
Common AM processes: PBF-LB, DED-Arc (WAAM) for large structures, PBF-EB for tungsten and titanium, MEX for tactical-grade polymer parts. Typical materials: Ti-6Al-4V, Inconel 625, tungsten, scalmalloy, AlSi10Mg, ULTEM 9085.
