Additive manufacturing, including emerging “3D printing” technologies, is booming. Last year an astronaut on the International Space Station used a 3D printer to make a socket wrench in space, hinting at a future when digital code will replace the need to launch specialized tools into orbit. Here on Earth, the Navy is considering applications for additive manufacturing aboard ships, and a commercial aircraft engine company recently announced its first FAA-approved 3D-printed part.
For millennia, materials have mattered—so much so that entire eras have been named for them. From the Stone Age to the Bronze Age to the Iron Age and beyond, breakthroughs in materials have defined what was technologically possible and fueled revolutions in fields as diverse as electronics, construction and medicine. Today, DARPA is pursuing the next big advances in this fundamentally important domain.
Hypersonic vehicles fly through the atmosphere at incredibly high speeds, creating intense friction with the surrounding air as they travel at Mach 5 or above – five times faster than sound travels. Developing structures that can withstand furnace-like temperatures at such high speeds is a technical challenge, especially for leading edges that bear the brunt of the heat.

The Defense Sciences Office is holding a Proposers Day meeting and webcast to provide information to potential proposers on the objectives of the new Materials Architectures and Characterization for Hypersonics (MACH) program. MACH seeks to develop new materials and designs for cooling the hot leading edges of hypersonic vehicles traveling more than five times the speed of sound.
Manufacturing by assembly provides the flexibility to freely combine materials and components and is fundamental to creating devices from cell phones to appliances to airplanes. However, assembly processes are currently not practical at the nanoscale. The A2P program was conceived to deliver scalable technologies for assembly of nanometer- to micron-scale components—which frequently possess unique characteristics due to their small size—into larger, human-scale systems.
