First 3D-Printed Multi-Story Building Erected in North America

The completion of a two-story building in Ontario, Canada marks the building as the first multi-story 3D-printed building in North America. While the U.S. and Canada have seen several 3D-printed buildings in recent years, until now all of these have been single-story buildings. Now, Canadian 3D construction printing company nidus3D, is proving there is much more to 3D construction printing than just smaller, one-story homes.

Nidus3D used the BOD2 printer from COBOD, a 3D construction printing solutions company whose technology has been utilized in several countries, as well as used to 3D print the first two- and three-story buildings in Europe. The BOD2 can print with real concrete with a particle size up 10 mm and 99% based on locally found raw materials. COBOD developed this low-cost solution, which is called D.Fab, in cooperation with Cemex.

The two-story house in Ontario will have a studio on the ground floor and a residence above, and the area of the building will be 2,300 square feet of mixed-use space. One of the new, innovative methods nidus3D developed in the project was a 3D-printed horizontal beam printed onsite and lifted into place by a crane.

With the 3D construction printing technology, nidus3D has set out to address the housing gap in Canada.

One of the many advantages of 3D-concrete printed houses is that they can be built quickly. The complete building took only 80 hours to print; nidus3D is convinced that future buildings will be made even faster.
