Additive manufacturing in Space is the use of additive manufacturing in spaceflight: rocket engine combustion chambers, satellite structures, propellant tanks, and in-space manufacturing demonstrators.
Why AM fits Space: Spaceflight is the strongest single-application growth driver for industrial metal AM. Rocket engine components (combustion chambers, regenerative cooling jackets, turbopumps) are almost universally AM-produced in new-design vehicles. SpaceX Raptor, Relativity Aeon, Rocket Lab Rutherford, ABL E2, Stoke Hopper, and Firefly Reaver are all heavily AM-derived.
Common AM processes: PBF-LB, DED-LB for large engine components, PBF-EB for refractory metals. Typical materials: GRCop-42 / GRCop-84 (NASA-developed copper alloys), Inconel 718, Ti-6Al-4V, scalmalloy.
