Abstract

In this work, two optical microfabrication methods are combined in a single system to enable automated fabrication of ordered three-dimensional microgranular crystals. The holographic optical tweezers approach offers precise and simultaneous handling of numerous microparticles, while two-photon polymerization enables selective joining of microparticles in desired crystal arrangements. Microgranular crystals exhibit unique nonlinear dynamic behaviors and have applications such as photonic crystals, acoustic lenses, and in shock absorbing materials. This novel fabrication approach holds potential to enable the next generation of hierarchical architectured metamaterials that cannot be fabricated with existing techniques.
