Just saw that this book was release sometime last month. It's titled "Printing Things" and it is all about 3D printing. It shows projects that can be created using 3d printers, as well as discussion with various industry insiders. It also covers all the latest technologies in the 3d printing industry. It shows different machines, tools and processes in 3d printing. Unfortunately it is priced at $60, which is a bit hefty in my eyes. However they also allow you to browse it for free online at http://usshop.gestalten.com/printing-things.html

Maybe one day, this will be a text book of sorts for 3D printing classes in college
