What is 3D printing? Which is also known as additive manufacturing. It's a way of making things. It's a form of digital fabrication, which is using a computer controlled tool to make a physical object. Consider an inkjet printer. It's a computer controlled tool, working in two dimensions. It has an ink cartridge moving back and forth depositing ink, and a second mechanism that feeds the paper. With these two movements combined, we get a two-dimensional image. A 3D printer just adds one more dimension, and instead of ink, it prints in a physical substance, like plastic.
It builds one layer up at a time, creating a 3D object. It's a little more complicated than that, but that's the general idea. Throughout the rest of this course, we'll talk about this process in greater detail.
