Abstract

In this paper, we achieved three-dimensional (3D) fabrication of long and heterogeneous microstructiires using an in situ photo-polymerization method advanced from our previous work, vertical continuous flow lithography (VCFL) [1], We succeeded in improving the resolutions of structures by using an UV absorber and a symmetrical vertical channel. In addition, our method can fabricate heterogeneous microstructures by exposing light patterns to multiple laminar flows. We demonstrated three-layered structures and long fibers whose cross-sectional geometries were clearly changed. We also fabricated two-layered Janus structures. We believe that this method will be applicable to making building blocks for bottom up tissue engineering.
