A bioink is defined as a biomaterial that is suitable for use in an extrusion based dispensing system known as a bioprinter. A biomaterial must possess the ability to maintain cell viability before, during, and after bioprinting. Often bioinks possess shear thinning characteristics but this property is not necessary for every bioink. Viscosities of bioinks can range from similar to water to approaching a paste-like consistency. A wide diversity of bioinks exist in the bioprinting field but the most common bioinks contain base components such as alginate, gelatin, synthetic networks like PEG and other engineered matrices. There are also thickening additives such as nanocelluclose, xanthan gum and clays to improve printabillity.
