The lovely folks over at Engagdet posted a nice overview of the 3D printers which are available today. So if you’ve got that money burning in your pocket and waiting to be spent…. – off you go.
I wouldn’t start off with 3D printing a moon base though. Let’s leave that to the pros at the European Space Agency…. (via TechCrunch). You might want to test your system before you go that big.
