The book is structured to serve the needs of several types of readers interested in 3D printing. It serves as a general introduction to the subject and its application in many fields, including industry, space, medicine, housing, clothing and consumer-oriented products. Next, methods and available software for creating a 3D model and the steps needed to insure a useful printed object are reviewed. The considerations involved in deciding whether or not to purchase a 3D printer or make use of an ever-growing number of printing services is included. The book concludes with an exercise which walks you through the characteristics of an available software package and the steps required to design a practical object. Doing this exercise - not just reading through it - will give you considerable insight into the capabilities of 3D software packages and, we hope, build your confidence and encourage you to try to create an object of your own choosing.
