Velo3D Qualifies Hastelloy X for its Sapphire Printer

July 9, 2020

Velo3D has released commercially a production process for the additive manufacturing (AM) of parts in Hastelloy X. The nickel-based alloy, suitable for the laser powder-bed fusion process, offers exceptional resistance to corrosion cracking and oxidation. Due to its high-temperature strength, Hastelloy X most often is used to manufacture combustion-zone parts for gas-turbine engines. 

Sierra Turbines recently partnered with Velo3D to print a prototype for its 20-kW microturbine engine, featuring a unicore in Hastelloy X. The company aims to print 95 percent of the engine through metal AM. 

“Sierra Turbines wants to lead aerial and power systems into a new way of manufacturing,” says Roger Smith, the company’s founder and CEO. “That means pushing the limits of what is possible to create a more-heat-resistant, lower-maintenance and higher-performing gas microturbine. Velo3D’s technology (including support-free printing capability) makes this the ideal manufacturing solution for turbines.” 

Adds Benny Buller, founder and CEO of Velo3D: “Power-generation applications such as industrial gas turbines are a key focus for Velo3D, so it is important that we qualify the right materials to serve that market. We will continue to add more of these types of compatible materials that enable customers to print parts they couldn’t before, yet with even better material properties than those produced by traditional manufacturing.”

Along with Hastelloy X, the Sapphire printer is compatible with Ti64, Inconel 718 and Al F357.
