Velo3D has qualified a nickel-based superalloy powder for its Sapphire® 3D printers

Specifically developed for Additive Manufacturing, Amperprint® 0233 Haynes®282® (15-45um) is a strengthened nickel-chromium-cobalt superalloy for high temperature applications.

Developed by materials producer Höganäs AB, under license from Haynes International, the powder is now qualified for use in Velo3D’s Sapphire® portfolio of 3D printers.

The vacuum induction melted, argon gas atomized and spherical powder shows a good balance of creep strength up to 930 °C, thermal stability, weldability, and fabricability.

“It’s inspiring to see what engineers have been able to build using metal powders from Höganäs and Velo3D’s support-free additive manufacturing process,” said Jerome Stanley, Höganäs Director of Global Sales, Customization Technologies. “The first parts printed using our Amperprint® 0233 Haynes® 282® powder are impressive, and I believe customers are only scratching the surface of what is possible with this superalloy. The powder, combined with Velo3D’s end-to-end solution metal AM solution, is an extremely effective combination for consolidating parts into monolithic structures to eliminate coefficient of thermal expansion in large, high-performance systems.”

Structural applications like energy generation, gas turbines, and space launch vehicles to build parts like heat exchangers, combustors, nozzles, combustion liners, rocket engines, and shrouded impellers are said to be a good fit for this material. These are applications that should withstand cracking and whose powder can be processed at near-melting-point temperatures. Furthermore, the material’s high weldability makes it ideal for parts in larger systems because of its ability to be welded to other components.

The first Sapphire® printer utilizing the Amperprint® 0233 Haynes® 282® powder will be operated by Duncan Machine Products (DMP), a contract manufacturer based in Duncan, Oklahoma. The system will be the seventh in DMP’s fleet of Velo3D Sapphire® printers, Velo3D says in a press release.

Our goal at Velo3D is to enable engineers to build the parts they want without compromising on the design or quality,” said Benny Buller, Velo3D CEO and Founder. “Qualifying new powdered metals, like Amperprint® 0233 Haynes® 282®, for use in our end-to-end solution further expands what’s possible with our additive manufacturing technology. Our partners at Höganäs provide materials of the highest quality and I look forward to seeing what our customers build using this amazing alloy.”
