ALBERTA — Roughly 12 months after breaking ground, the largest 3D printed housing development in Canada, Kakatoosoyiists, or Star Lodges in Blackfoot, is ready to welcome 16 members of the Siksika Nation in need of transitional housing. …Built in extruded concrete by nidus3D, a 3D construction start-up based in Ontario, the imposing nature of the structures is softened by their rounded corners, and a texture akin to the layers of sedimentary rock found in the Bearpaw Shale, a geologic formation that extends across the region. …The successful execution of the $2.6 million project is an important milestone in the advancement of Canada’s building technology, and it offers a glimmer of hope in mitigating the effects of chronic underfunding of Indigenous housing, especially for Alberta’s First Nations.  …Unlike wood-frame construction, 3D printing allows for thicker walls that accommodate more insulation material, at no additional cost.
