Completed TRL 4 (started at 2, targeting 4)
It is proposed to overcome current deficiencies in ISAM by developing thermal-curing thermosets with embedded fibers, and to move this new technology toward commercial feasibility. The work involves exploring benefits of low-gravity for innovative control of liquid spreading during extrusion, and quantifying the proper conditions for embedding composite fibers in the thermosets. The proposed effort includes these technical tasks: (i) Develop analytical simulations of the proposed ISAM methodology. (ii) Extrude droplets, puddles, and linear beads of thermal-curing thermosets on heated surfaces, and compare to simulations. (iii) Use calibrated models to predict performance in varied-gravity environments. (iv) Embed composite fibers into extruded thermosets using a modified 3D printer.
In the future, this work in design and predictive modeling will be useful for AM and deposition of new materials beyond thermal-curing thermosets with embedded fibers, such as recycled feedstock, concrete, high-temperature thermoplastics, and even regolith.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 4) — 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.
