Topology Optimization of Lightweight, Additively Manufactured Lattice Systems for Space Applications

The rapid rise of additive manufacturing is providing exciting opportunities for design and fabrication of novel architected materials, components and structures. The goal of this project is to exploit these opportunities by integrating the free-form design approach of topology optimization, the geometric capabilities and resultant material properties of additive manufacturing, and the multi-functional performance requirements of large-scale secondary structures for space applications. Research will focus on wire-fed additive manufacturing processes and representative manufacturing constraints, variations, and material models will be informed through experiments. Experimental observations will be integrated within the topology optimization approach to design high fidelity porous structures that are optimized for as-built, end-use conditions. If successful, this flexible design-manufacture approach has the capability to design and realize ultra-lightweight, multifunctional metallic structures for space applications, such as those used for equipment mounting.

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.
