Thin Wall Directed Energy Deposition JBK-75 and NASA HR-1 Nozzle and Representative

The National Aeronautics and Space Administration Shared Services Center seeks to issue a sole source contract for thin wall directed energy deposition fabrication of JBK-75 and NASA HR-1 nozzles and representative samples, with written capability submissions due June 12, 2026 at 1:00 p.m. Central Standard Time. This is a presolicitation synopsis under FAR 12.102(a), and NASA reserves the right to conduct this procurement on a full and open competitive basis depending on responses received.

Place of performance is Marshall Space Flight Center, Huntsville, Alabama 35812. The NAICS code is 332117, Powder Metallurgy Part Manufacturing; PSC is K099, Modification of Equipment—Miscellaneous. The procurement will be conducted using commercial item acquisition procedures under FAR Part 12.

The Statement of Work requires the contractor to demonstrate laser powder directed energy deposition capability to fabricate subscale thin-wall nozzles using a large-scale dedicated 557 laser system. The primary deliverable is printing the aft end of an RS-25 nozzle with combined height greater than 90 inches, diameter greater than 80 inches, and wall thickness capability of 1 millimeter. Additional deliverables include two NASA HR-1 7K thin-wall nozzles in AFT and FWD configurations, witness specimens using JBK-75, and process characterization samples. Work must be completed within 75 consecutive days or approximately 1,170 hours of machine time. The contractor must provide engineering services, tool code generation, operator support, consumables, machine maintenance, and final laser scanning inspection. Performance period is 9 months from authority to proceed. Interested organizations should submit written capabilities and qualifications to Cara Craft at cara.s.craft@nasa.gov; oral communications are not acceptable. NASA FAR Supplement Clause 1852.215-84 regarding the Ombudsman applies to this acquisition.
