The worldwide organ scarcity dilemma is being made worse by some of the recent advances in 3D bioprinting, which offer revolutionary opportunities for the repair of organs and tissues. The method enables the accurate manufacturing of biological tissues by stacking bioinks including cells, biomaterials, and growth factors. Unlike traditional organ transplants, where donor availability is a significant limiting factor, 3D bioprinting may create patient-specific tissues and organs, lowering the risk of immunological rejection and the need for ongoing immunosuppressive therapy. One of the most promising developments in 3D bioprinting is the capacity to print functioning circulatory networks, which are necessary for the survival and integration of huge tissue constructions.
