The uses for 3D printing are seemingly endless. We've seen the tech used by doctors, to build cars and for construction. While parts of a building have been 3D printed before, the United Arab Emirates National Innovation Committee is working to use the method for an entire office building in Dubai. Working with WinSun Global and a few other companies, the committee plans to use a 20-foot tall 3D printer to make everything on-site rather than fabricate the pieces and have them transported for assembly. WinSun Global has already printed a six-story apartment building and a house in China. As you might expect, the structure is small, measuring 2,000 square feet.
