You've probably heard of 3D-printed masks and even 3D-printed hands, as 3D printing technology has expanded in recent decades. Now one company says it has put up for sale the first 3D-printed home in the US. The Riverhead, New York home is for sale online through Zillow with a starting price of $299,999 (EUR 390,987). "This is the future, there's no question about it," said Kirk Andersen, director of operations for SQ4D Inc.  SQ4D uses automated construction methods, or 3D printing, to build structures and homes.

“What we want to do is print houses quickly, cheaply and robustly,” Andersen said. The company can set up its Autonomous Robotic Construction System on a construction site in six to eight hours. It then lays the concrete layer by layer, creating the foundation, the foundation of a house, and the structure's interior and exterior walls.

"It's a sea change for the workplace," said Andersen. 3D-printed homes could also end up having a radical effect on the wallets of potential buyers in America. "The cost of construction is 50 percent cheaper than the cost of comparable newly built homes in Riverhead, New York, and 10 times faster," said Stephen King, the Zillow Premier agent who owns the list of 3D houses. The cost of building the house is 50% cheaper and 10 times faster.

The 3D-printed home will include 1407 square feet of living space and will be constructed of concrete. The house has three bedrooms, two bathrooms and a detached garage for 2 cars. "I want people not to be afraid of automation, it's just a different tool and method. But it's still the same product; we're still building a house at the end of the day," Andersen said.
