Multi-material microstereolithography can provide highly functional 3D microdevices, which are expected to be applied in many fields such as medicine, photonics, micromachines, and sensors. However, there are still technical issues such as material waste and long fabrication time. Recently, we have developed a multi-material two-photon lithography technique using droplets that minimizes material waste. It was demonstrated that micro-optical components could be fabricated using this technique. We have also developed new photocurable materials such as silica slurry and conductive polymer. The combination of multi-material 3D printing and new functional materials is useful for the fabrication of highly functional microdevices.
