CHAPTER 63D-Printing the Model

IN THIS CHAPTER WE’LL DISCUSS how to print models that have been checked for printability and are ready to go. We’ll cover the 3D printing process, features of consumer-level printers, slicer software, and troubleshooting. We’ll also look at printing with a service bureau.

Types of 3D Printing

3D printing encompasses the different ways a physical model is built from a digital one. The .stl or other printable format file is a mesh inside an invisible shell. That mesh consists of hundreds or thousands of polygons and their X, Y, Z coordinates. The printer uses that information to create the physical model layer by layer. This is called additive manufacturing, meaning that material is added to create the item.
