Of the 121,000 people on donor lists in the U.S., over 100,000 need kidney transplants and thousands die each year while waiting. Bioprinting aspires to build healthy kidney tissue from a patient's own cells and transplant this to boost failing kidneys without fear of rejection... As the 21st century dawned, a handful of inspired scientists tried to use 3D printing to create living human tissue. Their vision was to restore the health of people with intractable injuries, such as worn out cartilage, severed nerves, ailing kidneys, failing heartsthe gamut of human frailties. Their modest success energized others to join the quest. Now, after two decades of ingenious effort and hard work, they have carved out a vibrant new discipline: bioprinting. In Bioprinting: To Make Ourselves Anew, physicist Kenneth Douglas casts an eye over the achievements and future of bioprinting. He explains the science with rigor but with a minimum of technical baggage. This is the first book on the subject written expressly for the lay audience: accessible and even entertaining. Douglas interviewed two dozen bioprinting researchers from around the world, and he enriches the narrative by sharing stories from the scientists behind the science. These contemporary vignettes are complemented by historical accounts of the women and men whose prescient contributions were foundational to the development of bioprinting. The book describes the challenges and accomplishments in the bioprinting of blood vessels, cartilage, skin, bone, skeletal muscle, neuromuscular junctions, liver, heart, lung, kidney, and so-called organs-on-a-chip, as well as the challenges of providing a blood supply and nerves to bioprinted tissues. This is a compelling tale of a work in progress: to imitate nature and help heal people with debilitating afflictions.

3D Printing in Medicine, Second Edition examines the rapidly growing market of 3D-printed biomaterials and their clinical applications. With a particular focus on both commercial and premarket tools, the book looks at their applications within medicine and the future outlook for the field. The chapters are written by field experts actively engaged in educational and research activities at the top universities in the world. The earlier chapters cover the fundamentals of 3D printing, including topics such as materials and hardware. The later chapters go on to cover innovative applications within medicine such as computational analysis of 3D printed constructs, personalized 3D printing - including 3D cell and organ printing and the role of AI - with a subsequent look at the applications of high-resolution printing, 3D printing in diagnostics, drug development, 4D printing, and much more. This updated new edition features completely revised content, with additional new chapters covering organs-on-chips, bioprinting regulations and standards, intellectual properties, and socio-ethical implications of organs-on-demand. - Reviews a broad range of biomedical applications of 3D printing biomaterials and technologies - Provides an interdisciplinary look at 3D printing in medicine, bridging the gap between engineering and clinical fields - Includes completely updated content with additional new chapters, covering topics such as organs-on-chips, bioprinting regulations, intellectual properties, medical standards in 3D printing, and more

This book introduces various 3D printing systems, biomaterials, and cells for organ printing. In view of the latest applications of several 3D printing systems, their advantages and disadvantages are also discussed. A basic understanding of the entire spectrum of organ printing provides pragmatic insight into the mechanisms, methods, and applications of this discipline. Organ printing is being applied in the tissue engineering field with the purpose of developing tissue/organ constructs for the regeneration of both hard (bone, cartilage, osteochondral) and soft tissues (heart). There are other potential application areas including tissue/organ models, disease/cancer models, and models for physiology and pathology, where in vitro 3D multicellular structures developed by organ printing are valuable.

Cell and organ printing has become a hot topic of scientific pursuit. Since several early publications between 2000-2003 that demonstrated proof-of-concept, cell and organ printing has blossomed into a rich area for scientific exploration that is being performed by researchers across the globe. Research has thoroughly demonstrated that living cells can be printed via a number of actuations including electrospray, extrusion via micropens and ejection through photothermal, thermal or optical mechanisms. This topic has come of age and it is ripe for exploring the underpinnings of the research to date. We have included research that uses printing technology to deposit or guide cells for tissue engineering applications and for completeness, we have also included chapters describing bacteria printing, biomolecular printing that could be used to build growth factors or recruitment macromolecules into scaffolds, tissue microdissection, as well as live cell printing. The breadth of approaches includes 3D freeform fabrication, ink jet, laser guidance and modified laser direct write techniques. We hope that this book is not the final word but the first word, defining how these tools have been used to take the first steps towards the ultimate goal of creating heterogeneous tissue constructs. Only time will tell whether cell printers will truly become organ printers, but the technologies described in this book hold promise to achieve what the field of regenerative medicine requires - functional 3D scaffolds with multiple cell types differentiated into functional tissue!

Essentials of 3D Biofabrication and Translation discusses the techniques that are making bioprinting a viable alternative in regenerative medicine. The book runs the gamut of topics related to the subject, including hydrogels and polymers, nanotechnology, toxicity testing, and drug screening platforms, also introducing current applications in the cardiac, skeletal, and nervous systems, and organ construction. Leaders in clinical medicine and translational science provide a global perspective of the transformative nature of this field, including the use of cells, biomaterials, and macromolecules to create basic building blocks of tissues and organs, all of which are driving the field of biofabrication to transform regenerative medicine. - Provides a new and versatile method to fabricating living tissue - Discusses future applications for 3D bioprinting technologies, including use in the cardiac, skeletal, and nervous systems, and organ construction - Describes current approaches and future challenges for translational science - Runs the gamut of topics related to the subject, from hydrogels and polymers to nanotechnology, toxicity testing, and drug screening platforms

This book offers the first comprehensive review of emerging cell-printing technologies, from the use of printing technology to deposit or guide cells for tissue engineering applications, to bacteria printing, biomolecular printing and live cell printing.
