Technology & Products
Key Products
Hydrogen-rich polymer-regolith composites for FFF 3D printing; Radiation-shielding polymer materials; Polymer-based corrosion and static-dissipative coatings
Technological Advantage
Proprietary polymer-regolith composite formulations for radiation shielding, supported by NASA SBIR contracts and peer-reviewed research (e.g., FFF 3D printing of polyethylene-based composites filled with Martian regolith). IP protection is possible via patent applications (e.g., US20230415927A1). Advantage is niche and protectable via formulations, though larger material suppliers could replicate with investment.
Differentiation
Value Proposition
Replaces heavy/bulky traditional radiation shielding with lightweight, on-demand 3D-printable composite materials made from local lunar/Martian regolith, cutting launch costs and logistics while enabling in-situ manufacturing of habitats.
How They Differentiate
Focuses specifically on radiation-shielding composite materials for AM in space, combining regolith with hydrogen-rich polymers, validated through NASA SBIR projects. No major direct materials competitor identified in the same niche.
