(a) SEM micrograph of the measured square polymerized structures; (b) $RMS$ calculated for surfaces fabricated with different $dx$ for SZ2080 containing PI and without it; and (c) AFM images of surfaces of pure and photosensitized polymer obtained with highest voxel overlap ($dx$ = 50 nm) as well as one which was produced via homogeneous UV exposure.
