Completed TRL 3 (started at 1, targeting 6)
We propose to use additive manufacturing (AM) to build a Coronagraph Bench engineering test unit. The versatility inherent in the 3D-printing process allows for a one-piece construction that promotes dimensional stability in dynamic thermal environments. This manufacturing technique, when used together with low expansion alloys, helps achieve the desired stability requirements.
This early-stage Innovation will be the first instrument built exclusively using AM. It will build on lessons learned from previous GSFC efforts to pioneer AM to print compact optomechanical components for higher stability, easier alignment and modularity of optical subsystems. This new manufacturing paradigm will enable new opportunities using the flexibility AM affords for building dimensionally stable light-weight structures that in the past required complex and costly machining operations. In addition, the rapid prototyping capability for proof-of-concept builds provides significant cost savings for design modifications, as for adapting this compact bench for different space platforms.
New manufacturing capabilities allow new instruments to be realized and constructed, allowing us to glean new knowledge which adds to our understanding. By these small candles in the darkness we illuminate little by little the dim outline that shapes the universe. Through AM, we can create new tools for discovery, ensuring stable, lighter weight structures for precision optics and sensors for future space missions.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
