The Department of Defense (DoD) is seeking proposals for the topic "OptiFrame- Topology Optimized Load-Bearing Airframe with Additive Manufacturing" as part of the SBIR 23.3 BAA. The objective of this topic is to develop a new design and manufacturing paradigm that combines topology optimization (TO) and additive manufacturing (AM) technologies to rapidly produce a low-cost, lightweight, full-scale airframe structure for a next-generation aircraft system. The new design tool and printed structure will be evaluated based on weight, stiffness, strength, cost, fatigue life, and manufacturing time. The project will be conducted in three phases, with Phase I focusing on feasibility and prior technology demonstration, Phase II on analysis, tool development, experimentation, and fabrication of prototype systems, and Phase III on the fabrication of more complex prototypes. The topic is restricted under ITAR and EAR regulations, and foreign nationals' involvement may be limited. The solicitation is closed, and more information can be found on the DoD SBIR website.
