The performance of a high explosive depends largely on its microstructure, which has historically been difficult to control. Antiquated manufacturing methods can be unreliable and inefficient, so a new way of working with explosives is badly needed.

A multidisciplinary team of scientists at Los Alamos is using 3D printing to improve the safety and performance of high explosives by revolutionizing not just how they are manufactured, but what they are made of as well.
