Abstract

3D bioprinting is an innovative technology that creates threedimensional biological structures layer by layer using living cells, supportive biomaterials, and bioactive molecules. It helps create tissues that work better by placing cells in a controlled and organized way, which solves some of the problems seen in older methods that use premade scaffolds. 3D bioprinting has transformative promise in biomedical research, with applications in organ transplantation, tissue engineering, and regenerative medicine. 3D bioprinting has opened new possibilities in medicine, such as tissue repair, drug testing, organ transplantation, and regenerative therapies. It replicates authentic tissues through a layer-by-layer deposition of bio-inks. This review provides a comprehensive overview of the main 3D bioprinting techniques, types of bioinks and materials used, and current applications in medicine. It also discusses the advantages, challenges, and future directions of 3D bioprinting, showing how it could transform personalized medicine, reduce the need for animal testing, and advancing healthcare outcomes.

Keywords: 3D Bioprinting, Bioinks, Bioprinting Techniques, Tissue Engineering, Regenerative Medicine.
