ExOne Qualifies Inconel 718 for Binder Jet 3D Printing
ExOne’s nickel-based alloy Inconel 718 is frequently used in the aerospace, energy and automotive industries, often for high-temperature applications, such as jet engines and tooling, or corrosive environments.
ExOne qualifies Inconel 718 for binder jet 3D printing.
The ExOne Co., a manufacturer of industrial sand and metal 3D printers using binder jetting technology, announced that its nickel-based alloy Inconel 718 has been certified as Third-Party Qualified, the company’s highest designation of material readiness for its metal 3D printers.
According to the company, Inconel 718 is frequently used in the aerospace, energy and automotive industries, and is known for high strength and hardness, with strong resistance to corrosion, chemicals and extreme temperatures ranging from sub-zero to 1300°F. It also said to have outstanding welding characteristics, and is often used for high-temperature applications, such as jet engines and tooling, or corrosive environments, such as those featuring seawater or acids.
Inconel 718 enables 3D printing of standard MIM powders, followed by standard sintering profiles and heat treatments, that deliver high-density results consistent with wrought material. Independent testing verifies that Inconel 718 3D printed and sintered by ExOne meets ASTM standard B637-18.
