Is 3D Printing and the Future?

Is 3D Printing the future?  There are some who are using this disruptive technology to push the envelope of manufacturing.  News such as 3D Printed Guns and Gun parts are what grab headlines but there are other areas that using it for other uses such as jewelry making to pot handles.  Is this a technology that will eat into the businesses of Hardware/Home Improvement type stores?  I suspect it is a distinct possiblity at some point in the next 25 years.
