Concrete + 3D Printing =
It can take anywhere from six weeks to six months to build a 2,800-square-foot, two-story house in the U.S., mostly because human beings do all the work. Within the next five years, chances are that 3D printing (also known by the less catchy but more inclusive term additive manufacturing) will have become so advanced that we will be able to upload design specifications to a massive robot, press print, and watch as it spits out a concrete house in less than a day. Plenty of humans will be there, but just to ogle.
So I might want to invest in concrete stocks.
As noted earlier today, this technology may one day become “normal” or the “new normal” or simply “what we’re building with now.”
It might take less than a week to build a concrete house using this technology, but I’d wager it would take at least three to five years to get approval from Albemarle’s Architectural Review Board. 🙂
