In addition to the high cost, building a new home can be a daunting task. Construction crews, electricians, plumbers, drywall workers and painters need to be hired and coordinated -- and even when everything seems to go right, costs often run higher than expected and the work never seems to be completed when promised. But all that is about to change. A new type of contractor has turned up in cities all over the United States: 3D printer builders. With housing costs rising, 3D-printed homes offer a less expensive, greener and quicker alternative to traditional methods of building homes, says Zach Mannheimer, CEO of Alquist 3D. He says 3D-printed homes are up to 10 percent cheaper than regular builds and can be completed within 60 days -- as opposed to the eight months it typically takes to build a traditional home. 3D-printed homes have already been turning up all over the world. A single-family home has been built in Borneo, Malaysia; an entire community of 100 3D-printed homes has sprung up in Georgetown, Texas; and a Phoenix company is selling the next-gen homes for less than $300,000 each. Would you feel safe in a 3D-printed home, or would you feel like the little pig who built his house from straw?
