Bioinks: Essential Materials for 3D Bioprinting in Tissue Engineering

Abstract

3D bioprinting has emerged as a transformative technology in regenerative medicine, enabling the fabrication of complex biological structures with high precision. Central to this innovation are bioinks—biocompatible materials that encapsulate living cells and biomolecules, allowing the creation of functional tissue constructs. Bioinks must possess suitable rheological, mechanical, and biological properties to support cell viability and structural integrity during and after printing. This article reviews the composition, classification, properties, and applications of bioinks used in 3D bioprinting. It also discusses current challenges and future directions in the development of advanced bioinks for clinical applications.
