Takenaka's WAAM Metal 3D-Printed Structural Node Receives Building Permit, World's First Use in a Formal Building

2026-11-10

On November 10, Japan's Takenaka Corporation announced that its WAAM wire-arc additive manufacturing metal structural node has passed approval and will be used in the Takenaka Group pavilion at the 2027 International Horticultural Exposition, making it the world's first metal 3D-printed structural component applied in a building that has obtained official construction permission. The WAAM node enables mold-free forming of complex shapes and, combined with optimized design, can reduce material usage, opening a certification precedent for metal additive applications in the construction industry. Buyer value: metal additive manufacturing is extending from aerospace to building structures, and the process path of mold-free forming of complex nodes plus material-reduction optimization is worth tracking.

MAMC 2026 Opens in Vienna: Refractory Metals Session Focuses on Tungsten AM, with Multiple Talks on PBF-LB/M and PBF-EB/M

The 10th Metal Additive Manufacturing Conference (MAMC 2026) is being held in Vienna from November 10 to 12, organized by the Austrian Society for Metallurgy and Materials (ASMET). The conference covers nine themes, including metal AM powders, laser and electron beam melting, and aerospace and defense applications, with November 11 being the second day. This edition features a special Highlight session on additive manufacturing of refractory metals. Plansee, the University of Innsbruck, JEOL, and others are giving multiple talks on PBF-LB/M and PBF-EB/M forming of tungsten. Addressing tungsten's extremely high melting point, low-temperature brittleness, sensitivity to impurities, and cracking tendency, the talks explore grain-refining alloying strategies and electron beam process optimization, with the goal of matching or even exceeding the performance of conventionally powder-metallurgy-produced tungsten parts. Tungsten and other refractory metals are critical materials for nuclear fusion, defense, and high-temperature applications, and their AM forming has long been limited by powder quality and process windows. For powder buyers, impurity control and batch consistency of high-purity fine-particle tungsten powder are prerequisites for scaling refractory metal AM, and attention should be paid to tungsten powder specification developments from leading manufacturers such as Plansee.

Academician Lu Jian Lectures at Beihang University: New Advances in Additive Manufacturing-Based Design and Manufacturing of Aerospace Alloys (Ultra-High Specific Strength Titanium Alloys)

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.

Providence Medical Technology's 3D-Printed Porous Titanium Cervical Fusion Implant Receives FDA Clearance

Providence 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.
