In 3D bioprinting, design and development of the biomaterial-inks/bio-inks is a major challenge in providing 3D microenvironments specific to anatomical and architectural demands of native tissues. The focal point of this book is to provide the basic chemistry of biomaterials, updates on current processing, developments, and challenges, and recent advancements in tissue-specific 3D printing/bioprinting. This book is will serve as a go-to reference on bioprinting and is ideal for students, researchers and professionals, working academia, government, the medical industry, and healthcare.

Three-dimensional (3D) printing enables the fabrication of tissue-engineered constructs and devices from a patient’s own medical data, leading to the creation of anatomically matched and patient-specific constructs. There is a growing interest in applying 3D printing technologies in the fields of tissue engineering and regenerative medicine. The main printing methods include extrusion-based, vat photopolymerization, droplet-based, and powder-based printing. A variety of materials have been used for printing, from metal alloys and ceramics to polymers and elastomers as well as from hydrogels to extracellular matrix proteins. More recently, bioprinting, a subcategory of 3D printing, has enabled the precise assembly of cell-laden biomaterials (i.e., bioinks) for the construction of complex 3D functional living tissues or artificial organs. In this Special Issue, we aim to capture state-of-the-art research papers and the most current review papers focusing on 3D printing for tissue engineering and regenerative medicine. In particular, we seek novel studies on the development of 3D printing and bioprinting approaches, developing printable materials (inks and bioinks), and utilizing 3D-printed scaffolds for tissue engineering and regenerative medicine applications. These applications are not limited to but include scaffolds for in vivo tissue regeneration and tissue analogues for in vitro disease modeling and/or drug screening.

Three-dimensional (3D) printing has evolved massively during the last years. The 3D printing technologies offer various advantages, including: i) tailor-made design, ii) rapid prototyping, and iii) manufacturing of complex structures. Importantly, 3D printing is currently finding its potential in tissue engineering, wound dressings, tissue models for drug testing, prosthesis, and biosensors, to name a few. One important factor is the optimized composition of inks that can facilitate the deposition of cells, fabrication of vascularized tissue and the structuring of complex constructs that are similar to functional organs. Biocomposite inks can include synthetic and natural polymers, such as poly (ε-caprolactone), polylactic acid, collagen, hyaluronic acid, alginate, nanocellulose, and may be complemented with cross-linkers to stabilize the constructs and with bioactive molecules to add functionality. Inks that contain living cells are referred to as bioinks and the process as 3D bioprinting. Some of the key aspects of the formulation of bioinks are, e.g., the tailoring of mechanical properties, biocompatibility and the rheological behavior of the ink which may affect the cell viability, proliferation, and cell differentiation.

Hydrogels represent one of the cornerstones in tissue engineering and regenerative medicine, due to their biocompatibility and physiologically relevant properties. These inherent characteristics mean that they can be widely exploited as bioinks in 3D bioprinting for tissue engineering applications as well as injectable gels for cell therapy and drug delivery purposes. The research in these fields is booming and this book provides the reader with a terrific introduction to the burgeoning field of injectable hydrogel design, bioprinting and tissue engineering. Edited by three leaders in the field, users of this book will learn about different classes of hydrogels, properties and synthesis strategies to produce bioinks. A section devoted to the key processing and design challenges at the hydrogel/3D bioprinting/tissue interface is also covered. The final section of the book closes with pertinent clinical applications. Tightly edited, the reader will find this book to be a coherent resource to learn from. It will appeal to those working across biomaterials science, chemical and biomedical engineering, tissue engineering and regenerative medicine.
