(a) Live (green)/dead (red) images for various UV exposure times under a fixed intensity (300 mW/cm2). (b) Live/dead and optical images of the printed mesh structure (8 × 8 × 0.5 mm3) for various UV intensities at a fixed exposure time (60 s). Measured initial cell viability with respect to the (c) UV exposure time and (d) UV intensity (n = 9, *P < 0.05). (e) Printability calculated using the pore size of the printed mesh structure (8 × 8 × 0.5 mm3) for various UV intensities (n = 9, *P < 0.05).
