Additive Manufacturing (AM), popularly known as 3D printing, is playing an increasingly significant role in the manufacturing arena. AM has revolutionized how prototypes are to be made and small batch manufacturing should be carried out.

At labs around the world, researchers have been experimenting with bioprinting, first just to see whether it was possible to push cells through a printhead without killing them (in most cases it is), and then trying to make cartilage, bone, skin, blood vessels, small bits of liver and other tissues. There are other ways to try to "engineer" tissue one involves creating a scaffold out of plastics or other materials and adding cells to it. In theory, at least, a bioprinter has advantages in manipulating control of the placement of cells and other components to mimic natural structures. But just as the claims made for 3-D printing technology sometimes exceed the reality, the field of bioprinting has seen its share of hype. The reality is that, although bioprinting researchers have made great strides, there are many formidable obstacles to overcome. Nobody who has any credibility claims they can print organs, or believes in their heart of hearts that that will happen in the next 20 years, but for operations like hip replacement, advance in Bio-printing has made customization of certain body parts possible. This book will start from the concept of Tissue Engineering, covering various approaches in Scaffolds for tissue engineering, Bioprinting techniques and Materials for bioprinting, Cell processing, 3D cell culture techniques, Computational design and simulation, multi-disciplinary approaches in bioprinting and finally cover the applications of bioprinting.

Rapid prototyping (RP) has revolutionized how prototypes are made and small batch manufacturing is carried out. This textbook covers the key RP processes, the models and specifications, and their principles, materials, advantages and disadvantages. It includes examples of application areas in design, planning, and biomedical engineering.
