For years, materials have been made at the nanoscale level to take advantage of their mechanical, optical, and energy properties, but efforts to scale these materials to larger sizes have resulted in diminished performance and structural integrity. Now, researchers describe a new process to create lightweight, strong and super elastic 3D printed metallic nanostructured materials with unprecedented scalability, 7 orders of magnitude control of arbitrary 3D architectures.

Strikingly, these multiscale metallic materials have displayed super elasticity because of their design...
