First 3D Printed Two Story House Constructed in Canada

  • This week, nidus3D in Canada accomplished that as they revealed the first 2-story 3D printed building finished in Canada.
  • Now, PERI and CIVE is following up with a 2-story building in the US which also doubles as the largest 3D printed resi-dential building so far in the USA.
  • In both projects a BOD2 3D construction printer from COBOD was used.

“Having the opportunity to be the engineers and general contractor for the first multistory 3D printed structure in the U.S. has been an honor,” said Hachem Domloj, CIVE President. “We can see how this technology and our team’s approach is providing the scalability to larger commercial developments. Collectively, we’re changing the way our country builds, and paving the way for more affordable housing, higher structural integrity, and faster building capabilities. The possibilities of 3D printing are endless!”

The 4,000-square foot project showcases the possibilities of 3D printing technology, mass customization, and design solutions that integrate conventional construction methods. With a hybridized construction method that combines concrete 3D printing with wood framing, this approach allows the two material systems to be used strategically and aims to increase the applicability of 3D printing in the US, where framing is the one of the most common construction techniques.

“For the design of the project, we developed a hybrid construction approach that couples innovations in concrete 3D printing with traditional wood framing techniques to create a building system that is structurally efficient, easily replicable, and materially responsive,” said Leslie Lok and Sasa Zivkovic, of HANNAH. “The project also highlights the exciting design potential of mass-customized architectural components to meet homeowner’s needs and to simplify building system integration. These design efforts aim to increase the impact, applicability, sustainability, and cost efficiency of 3D printing for future residential and multi-family buildings in the US”.

COBOD has an open-source strategy, partnering with customers, academic institutions, and suppliers around the world. COBOD is privately owned with General Electric, CEMEX, and PERI as key shareholders, and its partners further include Dar Al Arkan (Saudi Arabia), L&T Construction (India), and JGC (Japan).

The building design is conceptualized as a series of printed cores that contain functional spaces and stairs. The spatial cores are connected by wood framing to produce an architectural alternation of concrete and framed interiors. The project’s scalable design and construction process is applicable for multifamily housing and mixed-use construction. Using the COBOD BOD2 gantry printer, the project takes advantage of the printer’s modularity for its design layout.

PERI 3D Construction has an extensive record of advancing the implementation of 3D printing in building construction. Using COBOD BOD2 printers, PERI has completed six projects in Europe and in the US including the first 3D printed home in Germany and Europe’s largest 3D printed apartment building.

Philip Lund-Nielsen, Co-Founder & Head of COBOD North America, added: “We are proud to see more and more buildings being 3D printed with our BOD2 printer in North America as a consequence of our leading position in the market and the many 3D construction printers that we sold here”. He continued: “Our superior technology and leading position is documented by COBOD being the only supplier that has delivered 3D printers for construction of multi-story projects”.

Green Building Africa promotes the need for net carbon zero buildings and cities in Africa. We are fiercely independent and encourage outlying thinkers to contribute to the #netcarbonzero movement. Climate change is upon us and now is the time to react in a more diverse and broader approach to sustainability in the built environment. We challenge architects, property developers, urban planners, renewable energy professionals and green building specialists. We also challenge the funding houses and regulators and the role they play in facilitating investment into green projects. Lastly, we explore and investigate new technology and real-time data to speed up the journey in realising a net carbon zero environment for our children.
