On the afternoon of November 11, Beihang University hosted an academic lecture titled "New Advances in Additive Manufacturing-Based Design and Manufacturing of Aerospace Alloys," delivered by Lu Jian, Chair Professor at City University of Hong Kong and Academician of the French National Academy of Technologies. The lecture covered the process characteristics of additive manufacturing, metamaterial design, and artificial intelligence integration, systematically introducing typical defect control strategies and the principles of material property regulation, with a focus on progress in the design, manufacturing, and validation of ultra-high specific strength titanium alloys, including their application potential in aerospace and the low-altitude economy. Research interest in aerospace alloy additive manufacturing remains strong in academia, and the process-property relationship is a fundamental research theme underlying the application of superalloy and titanium alloy powders. For powder buyers, the validation of new grades such as ultra-high specific strength titanium alloys will drive demand for specialty titanium powders, and it is worth tracking their published data and powder grade requirements.
2026-11-11Providence Medical Technology has received US Food and Drug Administration (FDA) 510(k) clearance for its CORUS Posterior Cervical Stabilization System 3D-T (CORUS PCSS 3D-T), a next-generation version of the company's posterior cervical fusion (PCF) implant produced with additive manufacturing in porous titanium. The company announced on October 29 that surgeons in California and Virginia have completed the first commercial procedures with the device. The device is indicated for patients with cervical degenerative disc disease, serving as a supplement to PCF to stabilize spinal segments, and is placed on both sides of the spine via a posterior approach. Building on the core design of the earlier CORUS PCSS, it adds a proprietary titanium lattice structure modeled on cancellous bone within the body, with porosity and pore size consistent with published bone ingrowth research. According to the company, the lattice distributes loads evenly and provides structural support during fusion. Compared with the original machined implant, the 3D-printed version offers 1.5 times the surface area and 8 times the surface roughness, and leaves room for packing bone graft material inside the device. The earlier CORUS PCSS was evaluated in a randomized clinical trial (NCT04229017); when used in combination with multilevel anterior fusion, it showed higher fusion rates at 12 and 24 months and a significantly lower two-year surgical revision rate than anterior fusion alone, with interim results published in Spine in May 2025. Providence has not yet reported comparable clinical results for the 3D-printed version. The first commercial procedures were performed by orthopedic spine surgeons Mohsin Fidai at Adventist Health White Memorial in Los Angeles and Abilio Reis at Bon Secours Memorial Regional Medical Center in Mechanicsville, Virginia. The 3D-printed implant is built with a porous titanium lattice for full-segment fusion.
2026-11-10On November 10, CBC Metal Network reviewed the latest snapshot of the US Department of Commerce Bureau of Industry and Security (BIS) Commerce Control List (CCL): boron and boron alloy powders fall within the scope of ECCN 1C011.b. Exports of boron powder and boron alloy powder (including high-boron ferroboron powder) with a particle size of 60 microns or less and a boron content of 85% or more require a license, with control reasons covering national security (NS), missile technology (MT), and anti-terrorism (AT). Ordinary metallurgical-grade ferroboron (boron content 14%–26%) is not controlled, and companies must self-classify item by item based on the dual parameters of particle size and boron content. Such high-purity fine-particle boron powder is mainly used for energetic additives in rocket propellants, energetic materials, and special metallurgy. In the same period, China's Ministry of Commerce's Measures for the Investigation and Enforcement of Export Controls on Dual-Use Items (Draft for Comment) is open for public comment until November 29, and boron-related export enterprises face stricter declaration and compliance system requirements. For powder traders, export compliance screening needs to be moved forward to the order-taking stage, with close attention to changes in classification boundaries and declaration procedures on both the US and Chinese sides.
