The Department of Defense (DOD) is seeking proposals for the topic "Continued enhancement of Additive Manufactured Foundry-grade Sand Molds" as part of their SBIR 24.2 Annual solicitation. The topic is under the branch of the Air Force and has the topic number AF242-D005. The objective of the research is to advance the use of Lost-PLA technology to achieve aerospace-grade aluminum castings. The project aims to deploy PLA manufacturing systems compatible with the ATO, establish a digital workflow for reverse engineered parts, establish process controls and facility requirements for casting, and perform testing to demonstrate AMS 2175 quality. The project will be conducted in two phases, with no Phase I awards for this topic. The Phase II output will result in a low-cost ability for Tinker and other bases to expand to lost-PLA casting. The project is open for proposals until June 12, 2024. For more information and to submit a proposal, visit the solicitation agency's website at [solicitation_agency_url].
