Abstract
We propose an in situ photopolymerization method for three dimensional (3D) microfabrications which we call 'Vertical Continuous Flow Lithography' (VCFL). We used a digital micromirror device (DMD) as a dynamic photomask and a vertical flow of polyethylene glycol diacrylate (PEGDA) in a microchannel. VCFL can not only fabricate long (∼5 mm) structures but also control 3D geometries of structures. We experimentally demonstrated the fabrication of long fibers whose cross-sectional (diameters and shapes) geometries could be controlled. We believe that VCFL will be useful in bottom up tissue engineering to make long complex structures, such as branched blood vessels.
