Before You Begin
Look at the cover of this book again. What is that unusual looking device pictured there? Yes, it's a 3D printer, but what exactly does that mean?
This chapter will tell you. We're not going to bore you with a lot of techno mumbo-jumbo or a complete machine-by-machine history of how we got here; you can find all that on
Wikipedia.com or another web site. Instead, this chapter will provide a simple (and short) discussion on what this device is, what it does best, how it works (again, in simple terminology), and how to proceed through the following chapters to begin building your own 3D printer.
