The Department of Defense, specifically the Army branch, is seeking proposals for the Small Business Innovation Research (SBIR) program focused on "Additive Manufacturing for Circuitry." The objective is to develop open-source machine controller software and custom toolheads for 3D printers that facilitate the fabrication and repair of printed circuit boards (PCBs). This initiative aims to enhance existing 3D printing technology to address obsolescence in electronics and improve the supply chain's resilience by enabling rapid design and repair capabilities. Interested small businesses can submit Phase I proposals with a funding limit of $250,000 for a six-month performance period, with the application due by July 23, 2025.
