(A) Comparison of performance of TOPS-printed acrylamide/κ-carrageenan structures with existing technology of hydrogel fabrication in terms of lateral resolution and ultimate strain. (B) Comparison of performance of TOPS-printed acrylamide/κ-carrageenan structures with hydrogels and double-network hydrogels in terms of fracture energy and modulus of elasticity. (C) Plot depicting the mechanical performance (in terms of strain and strain) and comparison of printing performance (in terms of resolution) of TOPS-printed acrylamide/κ-carrageenan structures with other 3D-printed DN hydrogels. Note: all other studies only report lateral (XY) resolution. Since we printed 3D hollow structures with overhangs and undercuts, we have also reported the z (depth) resolution.^{26,27,30−32,49,52,53,55−59}
