| Abstract Scope |
Tungsten’s high melting point, hardness, and corrosion resistance make it invaluable for high-temperature applications, yet these same properties complicate traditional manufacturing. Laser-based additive techniques such as powder bed fusion (PBF) and directed energy deposition (DED) are commonly used, but they produce bulky shapes and are prone to thermal cracking. Vat photopolymerization offers a promising alternative, enabling the fabrication of complex structures with minimal cracking. This method produces micron-scale tungsten-loaded precursors, which are debinded in argon, then reduced and sintered in a 10%H₂–Ar atmosphere—avoiding pure hydrogen and mitigating cracking. The water-based photopolymer allows for increased tungsten content and compositional flexibility. This work investigates how changing the nickel ratio and the sintering temperature can alter the microstructures and thus the mechanical properties. |
