Many common materials exhibit different and potentially useful characteristics when fabricated at extremely small scales—that is, at dimensions near the size of atoms, or a few ten-billionths of a meter. These “atomic scale” or “nanoscale” properties include quantized electrical characteristics, glueless adhesion, rapid temperature changes, and tunable light absorption and scattering that, if available in human-scale products and systems, could offer potentially revolutionary defense and commercial capabilities. Two as-yet insurmountable technical challenges, however, stand in the way: Lack of knowledge of how to retain nanoscale properties in materials at larger scales, and lack of assembly capabilities for items between nanoscale and 100 microns—slightly wider than a human hair.

DARPA and the Navy recently agreed to locate a fabrication laboratory, or Fab Lab, at the Mid-Atlantic Regional Maintenance Center (MARMC, pronounced “mar-mack”) in Norfolk, Virginia, under DARPA’s Manufacturing Experimentation and Outreach Two (MENTOR2) program.

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.

The manufacturing process for defense systems—from aircraft to vehicles to ships—is extremely complex and fragmented, often demanding unique materials and processes, complex certification requirements and specifications, and specialized tools and equipment. The almost inevitable result: lengthy production timelines and high costs. The manufacture of diverse small parts for military systems could be made simpler, faster, and less expensive with the development of a tailorable composite feedstock material and a single tailorable forming method.
