On August 20, 2026, Shanghai Fengxian-based Pengtai Machinery entered the commercial aerospace sector with 3D-printed rocket nozzles as its core product. Its 'Aerospace Metal 3D Printing Technology Center' achieves a maximum build size of 1258×1258×1350 mm, enabling meter-scale integrated manufacturing. For example, a rocket nozzle approximately 1.2 meters tall requires nearly 20,000 printed layers and can process high-temperature nickel-based alloys and stainless steel. With combustion gas temperatures reaching about 3000°C, additive manufacturing enables complex internal cooling channels and near-zero material waste. Pengtai is also collaborating with Shanghai Institute of Technology to advance the 'Shanghai Pilot Base for New Materials in Large-Scale Additive Manufacturing Components,' which is the only pilot platform focused on additive manufacturing new materials among this round of Shanghai's municipal new materials pilot base applications. Value for powder buyers: ① Volume production of meter-scale rocket nozzles directly drives demand for large-format components made from high-temperature nickel-based alloy and stainless steel powders; ② Commercial aerospace 3D printing has shifted from 'optional' to 'essential,' making rocket engine powders (nickel-based, copper alloy, stainless steel) a high-certainty growth segment; ③ The pilot base focuses on new additive materials—watch for future external material validation and batch trial production opportunities that could generate powder procurement demand.
