I'm skeptical that 3d printed objects could replace very much of what we now obtain from factories. In industrial design, the materials and fabrication process are (supposed to be) selected very carefully with an eye towards cost, physical properties, chemical properties, etc. Even my phone case, which might be the simplest product I own, was made not just from any old plastic, but from a very particular plastic that's optimized for phone cases.
Whereas with 3d printing, we're currently stuck with a kind of plastic that's optimized for compatibility with a 3d printer. It's unclear whether we'll ever be able to print from other, better plastics. And that's saying nothing of other materials like steel, glass, and ceramic, which are often necessary in useful consumer products.
