From all the promises of 3D printing, it is living up to its promises. From GE manufacturing engine parts in giant 3D printers to designers bypassing the paper publishing altogether making them inhabit a future world still away from us.
On the personal level, 3D printing still sounds like a sophisticated coffee maker. If you don't drink coffee, you don't need it.
However new possibilities arise with new technologies. Researchers are investigating how to use 3D printing with materials found on the Moon or on Mars. This makes space travel sound like the greatest holiday invitation: just bring yourself. They can make their tools when they get there. They could literally print the cargo they need when they need it saving on weight.
Now, the same can easily be applied to consumer in a variety of ways. Print your camping gear when you need it. Going skiing? Just bring yourself. Print your skis once you get to the mountain from the model stored in your phone.
