If you want to make stuff, and by stuff I mean something more substantial than plastic light switch covers, go take a machine shop class at your local high school or community college. Go buy a used mill for the same $500 they say they can sell this for, and see what you can do with it. Removing material is an infinitely more practical way to create 3D objects. 3D printing is 95% hype, 4% misunderstanding, and 1% potential. Don't let the pseudo techies tell you what the future is.
