Abstract
The presented work will provide an overview of 3D microfabrication capabilities enabled by concurrent use of holographic optical tweezers and two-photon lithography in a single system. The hybrid nature of this technique allows for fabrication, manipulation, and assembly of microparticles in 3D. Exploiting these capabilities has enabled fabrication of some unprecedented metamaterials such as engineered microgranular crystals and lattices with embedded strain energy. We also demonstrated in situ characterization of 2PL structures by the means of optical manipulation and image processing.
