I guess my objection is that when I was younger, we owned an actual printer, and now, we don't. They're annoying. I think the more likely outcome is that you take your design to the "print shop" and get it printed. 3D printers likely require a lot of maintenance and calibration.
In my field (medical physics), the technology is constantly improving, but the maintenance requirements never go away. High precision requires high effort; high complexity, generally, requires high precision. That goes triple if you want to eat off it.
Plus, you probably want a variety of materials — are we going to eat off of a plastic spoon, or melt metal in our houses? Space Kinko's can stock everything from aluminum bronze to Zylon composites.
