a Shear-dependent viscosity profiles of resins with varying PACM content. b Photorheological response curves of resins with different PACM concentrations. G’ and G” represent the storage modulus and loss modulus, respectively. c Double bond conversion in resins as a function of PACM content. d Curing depth versus exposure time with and without photoabsorber addition. Error bars represent the standard deviation of 3 trials. e SEM image of a Gyroid lattice elastomer. f Photograph of vat photopolymerization 3D-printed elastomers with various lattice structures.
