In August 2026, Shenyang Duwei Technology Development Co., Ltd. completed the Environmental Protection Acceptance Monitoring Report for its 'R&D and Industrialization Project for Liquid Launch Vehicle Propulsion Devices Based on Additive Manufacturing.' The project commenced on March 20, 2026, was completed on May 20, and underwent on-site environmental acceptance monitoring on July 1–2. With a total investment of ¥100 million, the facility is located in the Shenyang Economic and Technological Development Zone, producing 16.5 tons annually of precision components—including thrust chambers and gas generators—for liquid launch vehicle propulsion systems. The project houses 17 metal 3D printers (domestic models: Eplus3D EP-M series and LaserMelting LiM-X series, a net increase over the originally planned environmental assessment), supported by 2 vacuum heat treatment furnaces, sandblasting, wire cutting, and other post-processing equipment, with 30 employees operating 250 days per year. Annual consumption includes 6.01 tons of superalloy powder, 4.51 tons of titanium alloy powder, and 6.04 tons of stainless steel powder (totaling approximately 16.5 tons), along with 400 tons of argon as shielding gas. Metal powders are used directly without on-site blending or reconditioning. Value for powder suppliers: ① Commercial aerospace liquid propulsion components (thrust chambers, gas generators) represent a high-value downstream application for superalloy and titanium alloy powders, with this single project consuming roughly 16.5 tons of three metal powder types annually; ② The installation of 17 domestic metal 3D printers validates the mass-production capability of domestic equipment (e.g., Eplus3D, LaserMelting) for critical aerospace components, accelerating the closed-loop synergy between domestic powders and domestic machines; ③ The environmental impact assessment approval (Shenhuan Jingkai Shenzi [2024] No. 38) requires mobile and stationary pollution sources to be included in independent acceptance, raising environmental compliance thresholds and demanding higher standards for batch testing and compliance documentation from powder suppliers.
