About this file
This is a Statement of Work (SOW) for NASA's Marshall Space Flight Center (MSFC) requiring precision laser powder bed fusion additive manufacturing of Inconel 718 turbine blades and shaft components for the InRoDES rotating detonation rocket engine development program.
The vendor must deliver fourteen build plates across four sequential phases: seven initial design-of-experiments (DOE) build plates optimizing hatch parameters to minimize dross formation on low overhang surfaces; three DOE build plates testing support structure configurations to achieve contactless or minimal-contact supports; one optimization build plate incorporating metallurgical inspection results with locally varying print parameters, including tensile bars, witness bars, and high-cycle fatigue coupons; and two final production build plates (four total final parts) using optimal parameters with no build interruptions permitted. All manufacturing must utilize an SLM Solutions 280 machine with 30-micron layer height for standard surfaces. The vendor is required to conduct a pre-build meeting with MSFC to review layouts and CAD models, maintain manufacturing traceability through signed traveler logs, notify NASA of any deviations or nonconformances, and document powder lot numbers. Post-manufacturing processes include ultrasonic powder removal between blades using isopropyl alcohol or MSFC-approved solutions, vendor-conducted inspection with MSFC approval before wire EDM or stress relief procedures, and stress relief before build plate removal. The period of performance spans July 2026 through November 2026, with deliverables including all manufactured parts, a deviations/nonconformance report, and a comprehensive build report shipped to Marshall Space Flight Center, Central Receiving, Building 4631, Huntsville, Alabama 35812.

Development Builds for Low Overhang Turbine Blades with Minimal Dross and Supports Statement of Work (SOW)
The National Aeronautics and Space Administration (NASA), specifically Marshall Space Flight Center (MSFC) has a need for precision laser powder bed fusion additive manufacturing of turbine blades with minimal to no dross formation on low overhang surfaces, minimal or no contact supports for an Inconel 718 turbine wheel and shaft component. These component builds are necessary for test hardware for the turbopump for InRoDES in house rotating detonation rocket engine development and test program.
SOW is as follows.
1. The vendor shall provide seven build plates of Low Overhang DOE samples with Inconel
718. Build will be with hatch parameter variation (energy density, laser speed, delay, hatch, and layer height etc.) to eliminate or minimize dross formation of low overhang and improve surface finish in low overhang regions of turbine blade coupons
2. The vendor shall provide three build plates of Low Overhang DOE samples with solid supports on inner and outer turbine diameters and supportless, no contact supports, or minimal supports on the turbine blade surfaces. Build will be with hatch parameter variation (energy density, laser speed, delay, hatch, and layer height etc.) to print supportless minimal contact support structures turbine blade coupons.
3. The vendor shall provide one build plate of turbine blade and shaft with DOE informed variable parameters on the turbine blades and near turbine regions to have optimized surface finish, minimal dross and contact less or minimally contacting supports. This will be with optimal energy density and laser parameters as informed by DOE builds and sectioning and metallurgical inspection provided by the vendor to recommend optimal locally varying print parameters along hatch lines and surface contours. Vendor shall provide tensile bars, metallurgical witness bars, and high cycle fatigue coupons with this build plate per MSFC guidance.
4. The vendor shall provide two build plates with two final parts on each build plate using the optimal locally varying print parameters along hatch lines and surface contours. For surfaces away from the turbine blades, standard SLM 280 print parameters for 30 micron layer height shall be used.
5. Vendor shall meet with MSFC prior to builds in order to review build layout and .stp model.
6. Vendor shall manufacture the part per NASA-MSFC drawing MC34120-003 and follow procedural steps outlined in 34120-MFG-PLAN where indicated. Manufacturing all delivered parts shall be with powder bed fusion laser beam method for alloy Inconel 718 with SLM Solutions 280 machine. Vendor may not use a different machine to maintain consistency with previous NASA MSFC build feature resolution and property testing.
7. Vendor shall notify NASA of any errors or issues during manufacturing, if switching powder between builds.
8. No build interruptions will be accepted for the final parts.
9. Vendor shall notify NASA if deviation or nonconformance occurs. Vendor shall provide MSFC with a final Build report. Vendor shall provide powder lot number(s) and traceability.
10. Vendor shall produce traceability of manufacturing process steps. Vendor shall initial the Manufacturing Travelers Log for each step in the manufacturing process and notify NASA MSFC of any deviations in step order or step instructions.
11. Final build must undergo powder removal between the blades. Powder within the hollow supports for main blisk structure are not a concern. The powder removal process must include ultrasonic with isopropyl alcohol or cleaning solution approved by MSFC Material Engineering group.
12. The vendor is responsible for inspection following powder removal and notifying MSFC for approval with documentation. The vendor is not to proceed with wire EDM removal of build plate or stress relief until MSFC has approved powder removal inspection.
13. The vendor shall not remove the build plate for the final part until stress relief.
14. Parts will include Qty 5 turbomachinery hardware to include turbine and shaft, coupons, and other complex DOE hardware builds.
Period of Performance (POP) July, 2026 through November, 2026.
