Innovative 3D Bioprinting Techniques: An In - Depth Review of Fabrication Methods and Emerging Tissue Engineering Applications
Deepti Niranjan
Abstract: Three - dimensional (3D) bioprinting has evolved as a revolutionary technology in tissue engineering and regenerative medicine. Bioinks, composed of living cells and biomaterials, enable the construction of layer - by - layer complex tissue structures that closely mimic human biological environments. The ability to create such biomimetic constructs holds immense potential for developing transplantable tissues like skin, cartilage, and bone. While current bioprinting techniques are restricted due to limitations with cell deposition and vascularization, numerous innovative approaches are emerging, each offering unique capabilities to address the critical shortage of transplantable organs. This review explores the various printing techniques such as extrusion based, inkjet, and laser assisted methods highlighting their advantages, limitations, and the innovative approaches being developed to address current challenges. Additionally, it delves into the bioink compositions that optimize cell viability and functionality, paving the way for future advancements in organ transplantation and personalized medicine.
