Shanghai Yunzhu 3D Technology Co., Ltd. has published a full-chain commercial space metal additive manufacturing solution on its official website, covering the entire process from design optimization and manufacturing to testing and inspection. Yunzhu 3D is a national-level specialized and innovative 'Little Giant' enterprise and a core additive manufacturing supplier for CAS Space (Zhongke Aerospace) rocket engines. It manufactures key components including the gas generator and precision valves for the Liqing-1 engine and the turbopump housing for the Lijian-2 rocket. The company operates more than 40 industrial-grade metal additive manufacturing machines with a maximum build size of 1,500 mm, enabling integrated forming of combustion chambers and large-diameter cabin sections. The commercial space metal additive manufacturing supply chain is rapidly taking shape—core components such as engine gas generators and turbopump housings are now being mass-produced via 3D printing, directly driving demand for superalloy and titanium alloy powders. This makes commercial space a key end-customer segment for powder manufacturers to track.
