Mighty Buildings is using 3D printing, novel materials and automation for prefabricated homes in a bid to transform the market. “We developed [our] material and printing technology after recognizing the need for a new way to build, in order to address the lack of efficiency in construction that has led to a global housing crisis,” Chief Sustainability Officer Sam Ruben says.

The recipient of the 2020 CAMX Unsurpassed Innovation Award, Mighty Buildings Inc. (Oakland, Calif., U.S.) was founded in 2017 with the goal of disrupting home construction using large-format 3D printing, advanced materials and automation.

“We observed that, after massive disruption going on in other sectors, home construction in the U.S. was still using largely the same technologies and processes we have been using for decades and, in some cases, centuries,” says Sam Ruben, chief sustainability officer (CSO) and one of the company’s four co-founders. He adds that traditional home construction methods “are often labor-intensive, materially wasteful and energy-inefficient.”

This was particularly evident in California, which, as its population has grown, has faced a long-standing housing shortage and lack of affordable housing for low- to middle-income residents. In August 2020, the average price of a single-family home in California reached a record $706,900.
