I&#x27;m thinking if I want to spend a bit of money on a computer-controlled making gadget I&#x27;d probably do better with a laser cutter. That covers a lot of cases (e.g. a gear should be just as easy on one of those as with a 3D printer, right?), and my impression is that the people I know with those tend to make more useful things than those with 3D printers, largely because of the material flexibility. Am I missing something?
