Comparing 3D printing techniques

When we refer to 3D printing techniques, we refer to the mechanical process that is used to create a model, layer by layer, through an additive approach. You may be surprised to learn that there are many different types of 3D printers out there, each using a different type of material and method to create a 3D part. We won’t be learning about all the available options in this book; instead, we will focus on the ones that are most widely used in both hobby and industrial settings.

Fused Filament Fabrication

Fused Filament Fabrication (FFF) is one of the most versatile and commonly used 3D printing production methods. The way this type of 3D printer works is by melting a roll of material, called a filament, while pushing that material through a nozzle, as shown in Figure 10.7:

To understand how this works, think of a hot glue gun. Like glue sticks...
