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.
