Nidus3D erects the first 3D-printed two-story building in North America
Although several 3D printed buildings have been erected in the United States and Canada in recent years, they were all single-story buildings. Today, Canadian construction 3D printing company nidus3D completed printing a two-story building in Ontario, the first 3D-printed multi-story building in North America.
The company used Cobod’s BOD2 3D construction printer, which can print with real concrete with a grain size of up to 10mm and 99% made from locally sourced raw materials.
The two-story, 2,300-square-foot home will feature a studio downstairs and a residence above. A new method developed as part of the project was the on-site 3D printing of a horizontal beam, which was lifted into place by a crane.
Cobod and nidus3D both believe that this new way of building will be a game changer in the face of the housing crisis in Canada.
“We have a severe shortage of skilled labor and a massive and growing demand for housing across Canada,” said Ian Arthur, one of the founders of nidus3D. “So if we don’t start looking for new ways to build, we’re never going to catch up. It is part of our core values, to seek solutions to solve the housing crisis and to help build affordable housing using 3D printing.
One of the many advantages of 3D printed concrete houses is that they can be built quickly. The complete building took only 80 hours to print, compared to 200 hours for the first building.
