Defense AM becomes key growth driver as SSAB unveils world's first AM armor steel powder Armox 500 AM at Eurosatory; U.S. Navy approves 182 AM parts for shipboard use, with $450M allocated for large-scale WAAM. A-share metal powder stocks surged on June 15: Boqian New Materials hit daily limit, Yuean New Materials +13.67%, Youyan Powder Materials +6.06% (3D printing powder sales up 409% to 458 tons, 23.3% gross margin). Capital accelerates: TDK acquires Fabric8Labs for $400M, Rizhao launches space metal tech park ($2B phase 1), Siresi invests $919M in expansion. Recycling tech disrupts supply chain: NUST MISIS develops ultrasonic atomization for waste powder recovery (sphericity 0.90); RIT receives $3M NSF grant for molten metal droplet jetting, bypassing powder atomization. May 3D printer output surged 54.4% YoY, fastest among new productivity sectors. Key risks/trends include stable raw material prices, defense-driven AM demand, capital-market synergy, and structural shift toward small-batch alloy development.
