VIDEO: North America’s first 3D-printed two-story building erected in Ontario
Nidus3Dbased in Kingston, Ontario, recently completed what it says is the first three-dimensional (3-D) printed two-story building in North America, using its strategic partner Cobod InternationalBOD2 printing technology and concrete, on nearby Wolfe Island (see video below).
The 2,300 square foot mixed-use building – Nidus3D’s second structure, the first having been built earlier this summer – includes a studio on the ground floor and a residence above. Among the most unusual aspects of the project, a horizontal beam was 3D printed on site before being put into place by a crane.
It took 80 hours to print the building, compared to 200 hours for the first structure. The company says future buildings can be constructed even faster.
“We have a severe shortage of skilled labor and a massive and growing demand for housing across Canada,” says Ian Arthur, co-founder of Nidus3D. “If we don’t start looking for new ways to build, we’ll never catch up.”
Until now, 3D printed buildings in Canada and the United States have only been single-story structures, but technology from Denmark-based Cobod, of which Nidus3D is a distributor, has already been used to create two- and even three-story buildings in Europe.
The BOD2 can print real concrete with a grain size of up to 10 mm. This process, called D.Fab, was developed in collaboration with Cemexwhich is best known for the manufacture and distribution of cement, ready-mix concrete and aggregates around the world, but is also a key shareholder of Cobod, along with General Electric (GE) and Peri.
