The 3D bioprinting is an additive manufacturing technique that usually employs various bio-based polymers with application in different fields such as tissue engineering, food, and pharmaceuticals, among others. The improvement in properties materials and the discovery of new functionalities are key goals that cannot be reached without a well-controlled and better understanding of the preparation, characterization, and manufacturing of novel formulations, which constitute the starting points of the design of specific and adequate systems. Every day, advances in innovative bio-based polymers formulations open more opportunities and offer excellent properties such as ease of fabrication, higher mechanical/functional properties, high thermal stability, among others.

This special issue is designed to generate knowledge about the formulation and 3D printing of novel hydrogels/bioinks prepared from naturally derived components such as nanocellulose, alginate, chitosan and so on.

Original research, reviews, and perspectives are welcome in this collection.
