WebJan 28, 2024 · Bioink viscosity is a crucial parameter of the bioprinting process that always needs optimization to adjust the bioink flow and cell encapsulation efficiency, and tissue structure stability . Diverse bioink compositions existed to meet the requirements of specific printing technology. Hydrogels are promising candidates for developing of bioinks ... WebIn laser-assisted printing, a bioink with a viscosity of 1–300 mPa/s is loaded on a ribbon coated by a thin metallic film (gold or titanium) (Zennifer et al., 2024). A laser pulse induces metal vaporization, which ejects a droplet of bioink toward the substrate. This is a fast printing technique with high precision deposition, and the cell ...
