Next-generation Manufacturing based on Additive Manufacturing

Abstract

In this paper, micro stereolithography techniques are reviewed. A multi-material micro stereolithography system based on single-photon polymerization using multiple droplets is introduced as a novel method to create heterogeneous structures such as multicolor structures. Additionally, 3D-printed micromachines such as optically driven micropumps and topology optimized microtweezers are shown. The multi-material micro stereolithography will be useful for producing functional microdevices including microfluidic devices, micromachines and scaffolds.
