  There is an increase in demand for organs as transplantation is becoming a
common practice to elongate human life. To reach this demand, three-dimensional
bioprinting is developing from prior knowledge of scaffolds, growth factors,
etc. This review paper aims to determine the current status and future
possibilities of three-dimensional bioprinting of organs and evaluate the
benefits and challenges, along with the history of its development. Prior
research has viewed three-dimensional bioprinting as a technology that will
enable safer transplantation without graft rejection and provide demand-based
production. However, it faces challenges such as the need to improve
biocompatibility and biofunctionality, legal and ethical issues, and the need
to improve the technology itself. While the development of three-dimensional
printing organs is not yet completed, we are seeing improvements and expecting
it to be clinically applied soon.
