How 3D printing works

…How do you take an idea and print it in three dimensions?…In this video, we'll follow the four steps required…to take a digital file into reality with 3D printing.…First, you need a digital file.…To create one, you'll need CAD software. CAD means Computer Aided Design…and it refers to a wide variety of computer applications that help a user…create content.…In our case, we're going to be…specifically talking about 3D modeling applications.…

And, later in this course, we'll talk more…about the variety and styles of 3D modeling.…But what's important to know now, is that you can use…almost any 3D modeling application to create content for 3D printing.…So let's take a look at a CAD…file in Blender, an open source 3D modeling program.…This is the Stanford bunny, and it was originally scanned at Stanford University.…And it's a really common file that's used for testing computer applications.…This design is complete.…And the next step is to export it to a format that is ready for 3D printing.…

In nearly all computer modeling applications, you'll…
