ExOne says that it has third party qualified nickel-based alloy Inconel 718 for its metal 3D printers.
According to the company, Inconel 718 is known for high strength and hardness, with strong resistance to corrosion, chemicals and extreme temperatures ranging from sub-zero to 1300° F. It is often used for high-temperature applications, such as jet engines and tooling, or corrosive environments, such as those featuring seawater or acids.
Previously, ExOne had recognized Inconel 718 as an R&D material, which meant it had been deemed printable for researchers, supported by ongoing development.
‘Today’s qualification of Inconel 718, following on the heels of M2 Tool Steel earlier this year, shows the ExOne R&D team is aggressively delivering new materials for binder jet 3D printing,’ said Rick Lucas, ExOne CTO.
ExOne’s advanced compaction technology (ACT) reportedly enables the 3D printing of standard MIM powders as well as standard sintering profiles and heat treatment. The company said it can deliver high-density results consistent with wrought material, while independent testing has verified that Inconel 718 3D printed and sintered by ExOne meets ASTM standard B637-18.
