About this file
This is a Statement of Work (SOW) for NASA's Marshall Space Flight Center (MSFC) requiring large-scale manufacturing technology demonstration and fabrication services using Laser Powder Directed Energy Deposition (LP-DED).
The contractor must fabricate full-scale demonstrator chambers and qualification samples using NASA HR-1 Fe-Ni alloy and Ni-based alloys per NASA specifications. Key deliverables include a NASA HR-1 heat sink chamber, a Ni-alloy heat sink chamber, representative test samples, witness test specimens (round bars and harvest boxes), and comprehensive build reports with laser scanning inspection data. The components must achieve 1 mm wall thickness at diameters exceeding 80 inches with a combined height greater than 90 inches. All sample builds must use identical machine setup, parameters, and process parameters as the chamber demonstrator. The contractor shall provide a dedicated 557 laser system with a minimum build volume of 60 inches diameter by 72 inches height, operated within an inert gas chamber to minimize oxidation. The print production must be completed within 75 consecutive days (approximately 1,170 machine hours) and include engineering support for tool code generation, part design input, laser scan inspections, reporting, machine operators, all consumables (Argon nozzles, filters, inert gas), maintenance, and part removal. The contractor cannot utilize the dedicated machine for other customers without NASA authorization and will be paid for machine time regardless of whether the machine is running or idle. The Period of Performance is 6 months from Authority to Proceed, with all deliverables shipped to Marshall Space Flight Center, Central Receiving, Building 4631, Huntsville, Alabama 35812, Attention Paul Gradl.

NASA HR-1 Demonstrator Chamber and Qualification Samples Statement of Work (SOW)
NASA's Marshall Space Flight Center (MSFC) requires a large-scale manufacturing technology demonstration using thick and thin-wall Laser Powder Directed Energy Deposition (DED). This effort aims to complete fabrication of full scale chambers, material property testing process qualification samples, and process characterization samples using NASA HR-1 and specialty alloys per NASA and industry specifications and representative process witness samples. These samples are required to be identical to part fabrication for metallography and mechanical and thermophysical testing.
The SOW is as follows:
Task 1
1. The vendor shall fabricate a series of witness test specimens to evaluate the processing of NASA HR-1 according to NASA specification using laser powder directed energy deposition (LP-DED). The witness coupon specimens shall include round bars and harvest boxes, or otherwise specified by NASA, and be fabricated using identical machine setup, parameters, and process setup as the chamber demonstrator.
2. The vendor shall fabricate and provide engineering support for the LP-DED to complete all build samples with an approximate wall thickness of 1 mm and representative machine and parameters as a full scale heat sink chamber.
3. The vendor shall prepare build plates to support sample builds.
4. The vendor shall review final models and refine the build approach for the NASA HR-1 thin-wall and thick wall chambers and representative build samples.
5. The vendor shall provide design inputs and develop detailed toolpath strategies for confirmation by NASA.
6. Vendor shall demonstrate LP-DED using a large scale machine platform for capability to print a large scale component with a combined height of greater than 90” height and greater than 80” diameter.
7. Vendor shall provide capability within laser system for 1 mm wall thickness at diameters stated in Task 1, requirement #6.
8. The material shall be NSA HR-1 Fe-Ni alloy and Ni-based alloys per NASA requirements.
The use of virgin powder, 1x used, 2x, and 3x used is acceptable.
9. The print shall be performed within 75 consecutive days (or less), or approximately 1170 hours of machine time shall include the following:
a. Engineering Support for a dedicated 557 laser system (includes Tool Code generation, part design input, laser scan inspections, reporting, etc.)
b. Provide operator for machine setup and deposition.
c. Provide consumables, such as Argon nozzles, filters, and all utilities required for operation.
d. Provide a build volume at a minimum of 60” dia by 72” for component builds.
e. Provide an inert gas chamber as part of the build to minimize oxidation. Provide all argon and consumables.
f. Provide tool code required to complete large format samples.
g. Provide all maintenance on the machine during the period of builds.
h. Provide operators necessary to operate the machine.
i. Shall include other required direct costs such as consumables and necessary replacement components (inert gas, build-nozzle components, filters, etc).
j. All engineering support should be included as part of the continuous-build machine capacity. This includes all tool path generation, inspections, trouble shooting of build failures, reporting, etc.
k. Shall include removal of parts from the build plate as required.
10. The vendor shall complete the following sample builds:
i. NASA HR-1 heat sink chamber
ii. Ni-alloy heat sink chamber
iii. Representative test samples
11. All NASA HR-1 representative qualification witness samples shall use identical parameters to the NASA HR-1 heat sink chamber and representative powder approved by NASA.
12. Part should be run on the same machine consecutively with acceptable breaks as needed for expected or unexpected shutdowns or pauses.
13. NASA shall provide drawings, models, and dimensions as required.
a. NASA will have required parts, models ready in advance so the tool code generation has adequate time to be completed, along with required planning for powder availability, base plates needed and machined, etc.
14. Vendor will not utilize the dedicated 557 machine for any other customers work unless receiving required authorization from NASA. Whether machine is running or sitting idle NASA will still pay for the machine time per pricing listed below.
15. The vendor shall complete a final inspection of the hardware. The inspection shall be completed using laser scanning and compared to the build CAD geometry, the interim scan data or both.
16. A report shall be provided of the scanning data from the inspections.
Shipping
1. Contractor shall ship all deliverables and process development samples to:
Marshall Space Flight Center Central Receiving, Bldg 4631 Attn: Paul Gradl Huntsville, AL 35812
Period of Performance (POP)
• 6 months from authority to proceed (ATP)
Deliverables
1. Chamber hardware and witness coupons as outlined in Task 10.
2. Build report for witness coupon samples and chamber and any inspection reports.
