3D printing reaches new heights with two-story home
A 3D print er is taking home building to a new level — literally. The enormous print er weighing more than 12 tons is creating what is believed to be the first 3D- print ed, two- story home in the United States. The machine steadily hums away as it extrudes layers of concrete to build the 4,000-square-foot home in Houston. Construction will take a total of 330 hours of printing , said architect Leslie Lok, co-founder of design studio Hannah and designer of the home. “You can actually find a lot of 3D-printed buildings in many states,” Lok said. “One of the things about printing a second story is you require, you know, the machine…And of course, there are other challenges: structural challenges, logistic challenges when we print a second-story building." The three-bedroom home with wooden framing is about halfway finished and is being sold to a family, who wish to remain anonymous, she said. The project is a two-year collaboration by Hannah, P...
