In this study, we propose and develop a versatile microstereolithography system using a low-cost diode laser. This system enables to generate pinpoint photopolymerization at a focused spot inside a liquid photopolymer like two-photon microfabrication using a femtosecond pulsed laser. In addition, it also takes advantage of multiscale fabrication based on single photon process. We constructed a microstereolithography system using a 405 nm diode laser and galvano-scanner set. Then, the resolution of this fabrication system was experimentally examined. By using this system, we successfully fabricated three-dimensional (3D) microstructures including movable microparts. Moreover, large scale fabrication of 2D alphabetical patterns was demonstrated.
