One of the most intriguing, and possibly disruptive, technologies now emerging is 3D printing. While still expensive and relatively unpolished, this new method of manufacturing products - from medical devices to airplanes - could be on a path to revolutionize retail, shipping, and the general need for space. Currently, 3D printing is most often used in the real estate industry as a way of creating scale models for new developments. As the technology grows and becomes more commonplace, there may be huge changes coming to real estate from this emerging technology.
