Additive Manufacturing of Low Overhang Turbine Blades

The contract focuses on the additive manufacturing of low overhang turbine blade coupons using powder bed fusion laser beam technology with Inconel 718 alloy. The work involves performing development builds that incorporate a design of experiments (DOE) methodology to systematically vary process parameters aimed at achieving supportless printing of the blades. This approach is critical to advancing manufacturing techniques for turbine components with complex geometries and improving overall efficiency and performance. Issued by the NASA Shared Services Center under the National Aeronautics and Space Administration, the subcontract falls under the NAICS code 332999, which pertains to miscellaneous fabricated metal product manufacturing. The solicitation was posted on June 15, 2026, with a response deadline of June 17, 2026. While specific location details and points of contact are not provided, the contract underscores NASA's ongoing efforts to innovate in advanced manufacturing for aerospace applications through controlled experimentation and optimization of additive manufacturing processes.
