Notable Technical Inquiry

European Energetic Additive Manufacturing (AM) Research

  The Defense Systems Information Analysis Center (DSIAC) was tasked with determining the extent of energetics additive manufacturing (AM) research and development capabilities in Europe. DSIAC searched available resources for any projects or research being performed by universities or defense organizations in Europe that involve the three-dimensional printing of energetic munitions, explosives, propellants, or rocket engines. There were a few organizations and universities that had…

Qualification and Certification of Powder Bed Fusion Additively Manufactured Components

Additive manufacturing (AM) is, and has been, a technology gaining traction for replacement parts and optimally designed structures throughout industry. However, with the lack of military or U.S. Department of Defense (DoD)-approved qualification and certification (Q&C) processes (outside of NASA standards), the utilization of AM throughout the Services and DoD certainly isn’t as trusted when…

Laser-Cladding Materials

This inquiry focuses on research on the mechanical properties of different substrate/deposited material laser-cladding combinations, specifically those that do not require a heat treatment, as well as the potential of laser cladding as an alternative to chromium plating. A wide variety of substrate and deposited materials is summarized, although there was a substantial lack of…

NSWC Indian Head Division Battle Lab

In the last decade, Warfighters have grown reliant on commercial-off-the-shelf (COTS) equipment to meet their operational needs rather than use traditional U.S. Department of Defense acquisition paths. Although COTS systems may offer a responsive and rapid procurement, they carry a substantial risk to front-line Warfighters due to lack of objective test and evaluation in realistic,…
