With the advancement in modern science and technology, organ failure or deterioration caused by the acute/chronic diseases, congenita malformations, and traffic accidents have become the most prominent social problems. As per the Journal of Chinese Medical Ethics, there are around 1.5 million patients who require organ transplantations in China every year, but only less than 1% of patients can obtain suitable organs. As compared to the traditional artificial organs made up of polymers or metals, the bioartificial organs are made up of living cells and biomaterials. A wide variety bioprinting strategies have been developed to tackle the challenges for the manufacturing of bioartificial organs with physiological functions. The objective of these strategies is to build complex organ geometries through a spatiotemporal pattern of heterogenous types of bio-inks, especially cells.
