3D printing is just additive manufacturing, where you start with nothing and add material until you build up the part you want. As opposed to subtractive manufacturing where you start with a block of material and remove stuff.

Yes, I know what it is.
Sorry, I didn't mean to imply that you don't. I'm just saying it's a broad category of processes. How frivolous it is depends on what you're doing with it. And you're completely right, there's a lot of frivolous stuff. A lot of serious stuff, too.
