On November 11, the 10th page of PLA Daily published the feature "Metal 3D Printing Accelerates the Rewriting of Modern Military Industry": metal additive manufacturing is moving from trial production toward the systematic manufacturing stage, and the logic of military production and maintenance support will therefore be reshaped. Landmark cases: in March 2026, the U.S. Portsmouth Naval Shipyard, after inspection, testing and certification, welded and installed a 3D-printed copper-nickel flange onto the piping of the Virginia-class nuclear submarine USS Washington — "printed parts being allowed aboard the boat" became a systemic turning point; in July 2026, during the Rim of the Pacific exercise, the U.S. Navy for the first time deployed a containerized metal additive-subtractive hybrid manufacturing system in an aircraft carrier hangar, enabling on-site manufacturing and repair of key components. Domestic progress: China's independently developed 3D-printed minimalist lightweight micro turbojet engine completed flight testing in November 2025 (carried by a drone to 6,000 meters, flying for 30 minutes at a maximum speed of Mach 0.75), with the number of parts reduced by about 60% and simultaneous improvements in fuel consumption rate and thrust-to-weight ratio; India's ISRO integrated 14 parts of its PS4 liquid rocket engine into a single 3D-printed piece, shortening the production cycle by about 60%. Value for buyers: military additive manufacturing "moving from emergency response to systematic" means that the military certification and volume supply window for copper-nickel, titanium alloy and superalloy powders is opening, and shipborne/vehicle-mounted mobile manufacturing cabins will drive demand for on-site powder inventory and supporting consumables.
