I thought this could be a very interesting discussion.

What excites you the most about the future of 3D Printing?

Probably the idea of being able to have any item I want at the push of a button...

Need a new bezel for your laptop? DONE.
Need a fork for whatever reason? DONE.
Want a new phone case? HERE, HAVE A NEW ONE.

Personally, I like the idea of not only being able to independently create almost everything I need (Well, other than perishables, of course), but to be able to mass produce it without a factory or plethora of workers to do so. And, on an even larger scale, it fascinates me that emergency parts for broken machinery that would otherwise take a few days to ship could be made in a fraction of the time.
