North America’s first 3D-printed two-storey building erected

Canadian construction company Nidus3D has completed work on North America’s first 3D-printed two-storey building in Ontario.

The 2,300 sq ft structure contains a studio on the ground floor and a residence above. It took 80 hours to assemble and print, with Nidus3D predicting that future structures could be made more quickly.

Ian Arthur, Nidus3D’s founder, said: “We have critical shortfall of skilled labourers, and a massive and growing demand for housing all across Canada. So, if we do not begin to look at new ways of building, we’re never going to catch up. It is part of our core values, to seek solutions to address the housing crisis and to help build affordable housing with the help of 3D printing.”

Nidus3D used technology created by Danish 3D printer maker Cobod. Philip Lund-Nielsen, Cobod International’s co-founder, said: “Our technology and 3D construction printers enable faster execution of construction projects, as well as more efficient construction at lower cost due to the lower labour requirements and usage of low-cost concrete.

“Cobod’s 3D construction printers have been used all over the world, and while this two-storey building in real concrete is a first and a great success for us in North America, the world-wide success of our technology proves the wide scale applicability of our technology.”
