“…After deposition, the ink is immediately cured into a solid object by different post-processes, such as photopolymerization or thermal curing [ 91 , 92 , 93 , 94 ]. Similar to FDM, DIW is also a high-efficiency method to deposit multi-material printed parts because it is of low cost and can be simply carried out [ 95 , 96 , 97 , 98 ]. More importantly, DIW exhibits tremendous potential because it is highly suitable for printing a large variety of different functional materials through multiple inkjet heads or nozzles to deposit different materials, including metallic particles [ 99 , 100 , 101 ], ceramic particles [ 102 , 103 , 104 ], extracellular matrices [ 105 , 106 , 107 , 108 ], hydrogels, and elastomers and epoxy thermosets [ 109 , 110 , 111 112 ].…”
