Abstract

Multi-material micro stereolithography systems based on single-photon and two-photon polymerization using multiple droplets have been developed. In the single-photon process, several types of photocurable resins are stored on a palette that is moved by a translation stage. Multi-material 3D microstructures are formed by accumulating each layer in z direction while exchanging the resins. Using this system, multicolor 3D microstructures were created with multicolor photocurable resins. In addition, a multi-material two-photon lithography system was also developed. Metamaterials and micro optical elements were fabricated using multiple photocurable resins. These multi-material micro stereolithography systems are useful to create functional microdevices.
