Aheadd CP-1 NXG Specimen Build

Statement of Work (SOW)

The National Aeronautics and Space Administration (NASA), specifically Marshall Space Flight Center (MSFC) has a need for manufacturing of Aheadd CP-1 material testing and characterization specimens using a Nikon SLM Solutions NXG additive manufacturing machine to evaluate the viability of using this platform for cryogenic fluid management (CFM) components and to better characterize material produced on large scale laser powder bed fusion machines.

The SOW is as follows:

1. The vendor shall have experience manufacturing Aheadd CP-1 with laser powder bed fusion (L-PBF) additive manufacturing.

2. The vendor shall develop a build layout using vendor’s best practices, the specimen matrix, and build files or geometries provided by NASA, and review with NASA prior to manufacturing.

3. The provided build files shall be processed by the vendor using best practices to ensure the highest resolution feasible for the specimens and that sufficient stock material is added to account for build plate removal.

4. The vendor shall print labels on all specimens notating the build and specimen number.

5. The vendor shall de-powder the specimens and remove from the build plate using wire

EDM or bandsaw in the as-built condition.

6. NASA will provide detailed specimen matrix, specimen files, and discuss as necessary.
