The integration of three-dimensional (3D) printing technology has resulted in substantial advances in organ and tissue engineering. This study looks at current techniques to 3D printed organ and tissue engineering, emphasising the unique methodologies and materials used to generate viable biological constructions. We address the advantages and limits of several bioprinting processes, including inkjet, extrusion and laser assisted bioprinting, in reproducing the intricate architecture of natural tissues. The focus is on the creation and optimisation of bio-banks, which are critical for obtaining desirable mechanical qualities, biocompatibility, and biological interactions. The role of stem cells and growth factors in promoting tissue regeneration and vascularization is being investigated. Furthermore, we discuss the obstacles of scaling up 3D printed constructions for clinical applications, such as vascularization, immunological response, and long-term functioning. Emerging developments, such as the use of microfluidics and improved imaging techniques to monitor tissue growth in real time, are also highlighted. This chapter seeks to give a full overview of the promise and limits of 3D printed organs and tissue engineering by summarising its present and future directions.
