Bioprinting of strong hydrogel constructs with polymer-nanoclay composite bioinks. (A) Bioprinting of GelMA enriched with nanosilicate to achieve rigid complex structures. Reproduced with permission from ref.[70]. (B) Various 3D constructs bioprinted with a PEG-alginate-nanoclay hydrogel (from left to right: hollow cube, hemisphere, pyramid, twisted bundle, ear shape and nose shape). (C) Bioprinted PEG-alginate-nanoclay mesh undergoing repeated uniaxial stretching and recovering to its original shape. (D) Bioprinted PEG-alginate-nanoclay pyramid undergoing repeated compressions and recovering to its original shape. Reproduced with permission from ref.[81]. (E) Human L3 vertebrae bioprinted with various concentrations of MeHA in the bioink. Reproduced with permission from ref.[83].
