Reported on October 26, North Carolina State University, in collaboration with Oak Ridge National Laboratory, has for the first time installed 3D-printed full-scale tungsten tiles onto a tokamak fusion device for live testing. Tungsten tiles are core components of the tokamak divertor and first wall, required to withstand high heat flux and plasma bombardment. The team used electron beam melting to overcome the difficulty of shaping tungsten at high temperatures; the tiles are full-scale and have undergone non-destructive testing. The live test will verify the tiles' thermal fatigue and sputter resistance in a real plasma environment, providing data to support additive manufacturing standards for plasma-facing components (PFCs) in fusion reactors. Value for powder buyers: (1) As fusion components move from the lab to on-device testing, demand for standardized tungsten/tungsten-based powder specifications is beginning to form (purity, particle size, sphericity standards); (2) the US supply chain prioritizes domestic powders, and domestic Chinese tungsten powder can be developed against their published specifications; (3) if the live test passes, procurement of PFC replacement parts for devices such as ITER/CFETR will open up a long-term market.
