North Carolina State University, Oak Ridge National Laboratory, and JEOL Ltd. have collaborated to produce full-scale tungsten divertor tiles using electron beam powder bed fusion, and the tiles were installed in the lower divertor of the tokamak at the DIII-D National Fusion Facility in San Diego in July 2025. The additively manufactured tiles remained intact after 74 high-confinement mode plasma discharges. The tiles measure approximately 140 by 130 mm, whereas NC State's previous largest tungsten printed part was only about 50 mm. JEOL engineers printed both flat and dome designs on the large-format JAM-5200EBM machine at its Akishima plant in Tokyo, ORNL funded the fabrication, and NC State completed finishing by wire electrical discharge machining and CNC grinding. The project ran about eight months from invitation to installation. Tungsten melts at 3422°C but is prone to cracking below roughly 200 to 600°C, and most laser printing attempts have suffered from porosity and cracks; in electron beam powder bed fusion, the electron beam keeps surrounding material above 1400°C. Test buttons printed in 2025 withstood heat fluxes approaching 20 megawatts per square meter in DIII-D with minimal surface damage, which led to the full-scale tile testing that began in December. The project's material and process route builds directly on metal powder bed fusion: tungsten powder is melted layer by layer with an electron beam and then machined subtractively to final dimensions. Michael Kirka of Oak Ridge National Laboratory said that printing tungsten tiles that can be inserted into an operating tokamak and removed intact moves additive manufacturing in fusion from promising to proven. Florian Laggner, an assistant professor of nuclear engineering at NC State, noted that exposing additive manufacturing tungsten parts in DIII-D is generating fusion-relevant data on survivability and erosion.
