Session 24: Military & Security
Manufacturing Technologies to Enable Advanced Munitions
Thursday, June 22, 2017
2:25 PM - 2:45 PM
Manufacturing technologies are critical for the next generation of smart munitions for small and medium caliber applications. In order for new munitions to meet their intended performance requirements and stay within cost targets, several manufacturing technologies must be matured. U.S. Army ARDEC is investigating and developing techniques to apply printed materials onto a complex geometry to increase performance and reduce the weight and size of a variety of munitions and warheads. Current methods for printing high precision traces are limited to three-axis motion applications and incapable of complex surfaces. This limitation requires printing traces on a flat surface and wrapping them into the desired geometry. The current industrial base is not focused on overcoming these limitations as designs that utilize more complex techniques are not mature. In a similar fashion, work in the printing of specialized materials is very limited as the applications are almost all defense related. This study focuses on current research and development of six-axis capability necessary to print on hemispherical topography. Several examples will be presented to display the progression and the future direction of six-axis additive manufacturing by U.S. Army ARDEC.
Giuseppe L. Di Benedetto, Ph.D. is a Chemical Engineer in the Advanced Materials Technology Branch (AMTB) of the U.S. Army Research, Development, and Engineering Command (RDECOM) Armament Research, Development and Engineering Center (ARDEC). Dr. Di Benedetto graduated with honors and completed a Bachelor of Science (B.S.) in Chemical Engineering at New Jersey Institute of Technology (NJIT) in May 2002. He graduated and completed a Doctor of Philosophy (Ph.D.) in Chemical Engineering at NJIT in January 2009. Soon after, he joined U.S. Army RDECOM-ARDEC at Picatinny Arsenal, NJ, USA, in June 2009.
During his 7.5 years at U.S. Army RDECOM ARDEC in the AMTB, Dr. Di Benedetto has served as the Technical Lead and/or the Technical Point of Contact for many materials emphasized research and development projects. These projects range from the areas of power and energy, printed materials and electronics, additive manufacturing, material characterization, material degradation, and reliability. This work has resulted in publications in peer-reviewed journals and conference proceedings, and paper and poster presentations at national and international conferences. He also closely collaborated with industry, universities, and other government agencies on research programs and projects.
