Rocket Lab has successfully completed a hot-fire test of its Archimedes engine. Critical subsystems, including the turbopumps, valves, and main combustion chamber, are produced using 3D printing. This approach enables shorter production cycles, optimized geometries, and structural robustness designed to withstand up to 20 reuse cycles per engine.
