Energetics Technology Center (ETC) interns recently contributed to a research publication in collaboration with the U.S. Army Combat Capabilities Development Command, known as DEVCOM, Army Research Laboratory, supporting efforts to advance synthetic material modeling and improve understanding of electromagnetic exposure impacts on Soldiers.

The publication focuses on the development of an automated modeling routine that introduces porosity, an interconnected network of holes or channels, into 3D objects using Blender, a software platform for 3D modeling and simulation. The approach enabled researchers to modify the density and material properties of objects for a range of scientific and engineering applications.

At DEVCOM ARL, the routine is being used to create porous synthetic bone materials capable of absorbing specialized gels to better replicate the mechanical and electrical behavior of human tissue. These models can then support safer, more controlled testing of how electromagnetic radiation from systems such as radar and portable jammers may affect the body.

While the research concept originated with ARL scientists, ETC interns played a role in bringing the project to life. Interns developed and refined the modeling algorithm, implemented the approach, tested multiple designs, and produced physical samples using 3D printing. The team also coordinated high-precision microCT scans to compare the printed structures against the intended digital models and created documentation to support future use by other research groups.

Beyond its current application in synthetic biological materials, the modeling approach has broader potential for researchers and manufacturers seeking to create lightweight or porous materials for physical products, simulations, or advanced manufacturing applications.

The collaboration reflects ETC’s continued partnership with DEVCOM ARL and commitment to providing hands-on technical opportunities for emerging STEM talent. Through projects like this, interns gain practical experience working in laboratory and research environments while contributing directly to real-world defense and scientific challenges.
