Hastelloy X can now be used with Sapphire® 3D Metal Printer, making additive manufacturing feasible.

FREMONT, CA: VELO3D, the digital manufacturing innovator, is having a commercial release of a production process for additively manufactured parts in a nickel-based alloy, Hastelloy® X. It is a good fit for the laser powder-bed fusion (LPBF) process and displays extreme resistance against oxidation and cracking from corrosion. The alloy is used to create components for gas turbine engines for combustion zones, owing to its ability to withstand high temperatures.

“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,” says Benny Buller, Founder, and CEO of VELO3D.

In a recent partnership, leading air mobility and power generation company Sierra Turbines and VELO3D collaborated to print Hastelloy X unicore-enabled prototype for their 20-kilowatt microturbine engine. The design and geometric freedom that VELO3D offers with its SupportFree process can print almost 95 percent of the engine through additive manufacturing methods. The patented SupportFree process allows the creation of intricate cooling networks and fuel delivery channels. These capabilities are crucial for high-output transmission of fluid and electrical power.  

“Sierra Turbines wants to lead aerial and power systems into a new way of manufacturing. 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 makes this the ideal manufacturing solution for turbines,” comments founder and CEO, Roger Smith.

VELO3D’s Sapphire metal AM printer can now be used with Titanium64, INCONEL® alloy 718, Aluminum F357, and Hastelloy X. As a digital manufacturing expert, VELO3D, headquartered in silicon valley, California, offers numerous design innovations that reduce dependence on support structures for 3D metal printing.
