a The wettability of different precursor liquids. Images were captured 0.5 s after droplet contact with the surface. i: a non-phase-separated AAm50-DMF0 gel. ii: a phase-separated AAm50-DMF100 gel cured in the absence of oxygen. iii: a phase-separated AAm50-DMF100 gel cured in open air. b Illustration of the decay of surface inhibition along the Z-axis depth in a cured resin layer. c The effect of irradiation time on the depth of inhibition. Data are presented as mean values +/- SD (n = 5). d Depth profile of the molecular weight. Irradiation time: 5 s. Data are presented as mean values +/- SD (n = 3). e Rapid printing with a printing speed of 375 mm/h.
