Offerors must disclose any proposed use of foreign nationals (FNs), their country(ies) of origin, the type of visa or work permit possessed, and the statement of work (SOW) tasks intended for accomplishment by the FN(s) in accordance with the Announcement. Offerors are advised foreign nationals proposed to perform on this topic may be restricted due to the technical data under US Export Control Laws.

 

OBJECTIVE: Advance the use of Lost-PLA to be able to achieve aerospace grade aluminum castings. Upon completion of the project, Tinker will be able to cheaply deploy investment casting type capabilities within REACT within an easily scalable workflow.

 

DESCRIPTION: -Deploy PLA manufacturing systems within REACT that are compatible with the ATO.

-Establish digital workflow to go from a reverse engineered part to a PLA print capable of operating as a casting positive

-Establish process controls and facility requirements for the investment and set up of the casting

-Perform sufficient testing to demonstrate AMS 2175 quality of Class B or

 

PHASE I: As this is a Direct-to-Phase-II (D2P2) topic, no Phase I awards will be made as a result of this topic. To qualify for this D2P2 topic, the Government expects the applicant(s) to demonstrate feasibility by means of a prior “Phase I-type” effort that does not constitute work undertaken as part of a prior or ongoing SBIR/STTR funding agreement. Applicant(s) must be able to demonstrate ability to use evaporative casting methodologies (e.g. lost-PLA or lost-foam) previously. PLA or foam tooling manufacturing must be of additive/digital variety. The applicant(s) must be able to provide sufficient data for the government to determine feasibility.

 

PHASE II: -Deploy PLA manufacturing systems within REACT that are compatible with the ATO.

-Establish digital workflow to go from a reverse engineered part to a PLA print capable of operating as a casting positive

-Establish process controls and facility requirements for the investment and set up of the casting

-Perform sufficient testing to demonstrate AMS 2175 quality of Class B or higher

 

PHASE III DUAL USE APPLICATIONS: Output from Phase II will result in a low cost (~$15k-30k) ability for Tinker to expand to lost-PLA casting. Other bases with the ability to melt (e.g. Rock Island Arsenal in the US Army). The ALC will purchase technology using organization (working capital) funds.

The Defense Advanced Research Projects Agency (DARPA) is specifically interested in technologies related to additive manufacturing techniques, materials, propulsion combined cycles, and hot structures. They are also looking for advancements in the understanding and characterization of novel fluid dynamics that enhance propulsion performance. The objective is to achieve coherence between a cooperating set of commodity devices, resulting in increased thrust to weight, fuel efficiencies, and propellant mass fractions. This solicitation is open for Phase II proposals only, and Phase I proposals will not be accepted or reviewed. Phase II will involve designing and evaluating enabling technologies at the system and subsystem level, as well as advancing modeling and simulation tools. Physical hardware proposals should include development, installation, integration, demonstration, and/or test and evaluation of the proposed prototype system. Software or advanced tool development proposals should have a development approach anchored in the physics of the problem and ways to validate the software against existing test data. The Phase II effort consists of a base period of 12 months and an option period of 12 months. Phase III of this project will focus on transition and commercialization of the developed technologies. The proposer is required to obtain funding from private sector or non-SBIR Government sources to develop the prototype software into a viable product or non-R&D service for sale in military or private sector markets. The technologies developed under this topic will have applications in both commercial and military sectors, including commercial transportation, high-speed delivery, and responsiveness to fluidic environments.

DOD SBIR 24.4 Annual - Automated Functional Grading of Materials for Directed Energy Deposition Additive Manufacturing
Department of Defense
The Department of Defense (DOD) is seeking proposals for the development of software for automated functional grading of materials in directed energy deposition additive manufacturing. This research topic aims to enable the production of complex, multi-material munitions with enhanced lethality. The software should allow for the creation of functionally graded materials (FGMs) by generating tool paths for multi-material grading in at least three directions. The software should be capable of accepting user inputted gradients for combinations of at least four metals simultaneously. In Phase I, a proof-of-concept software should be developed to print FGMs on a directed energy deposition additive manufacturing printer. The software should be able to accept user-generated gradients and demonstrate control over changing the mixing of metals. Materials characterization should be performed to verify the chemistry of the deposited gradient. In Phase II, the software should be expanded into a prototype capability, allowing for user-defined material grading using up to four metals simultaneously. Graded test coupons should be fabricated in multiple orientations, and a demonstration part containing a functionally graded material should be generated. Materials characterization should be performed for each coupon. The development of this software will greatly increase manufacturing capability and potentially help increase widespread adoption of directed energy deposition additive manufacturing technology. The military and civilian sectors, including manufacturing research, aerospace, mining, power, tool manufacturing, and medical applications, would benefit from this technology. The solicitation is open until March 31, 2025. For more information, visit the [solicitation link](https://www.sbir.gov/node/2651311).
