Penn State Tackles Alaska’s Housing Shortage with 3D Printed Homes Initiative

In Alaska, where rugged landscapes and harsh winters have exacerbated the housing crisis , researchers at Penn State have developed a promising solution to alleviate the state’s housing shortage. Led by Professor José Pinto Duarte, Stuckeman Chair in Design Innovation and Director of the Stuckeman Center for Design Computing in the College of Arts and Architecture’s Stuckeman School, the research team at Penn State University has turned to 3D printing technology to address the state’s critical need for affordable housing. Their vision? To build sustainable, warmer, and more cost-effective homes for Alaskan residents in need.

Alaska faces a pressing demand for new housing, with current estimates suggesting a need of 27,500 units over the next ten years to combat overcrowding and unsanitary living conditions. In recent years, traditional construction methods have struggled to meet this growing demand, particularly in remote areas where rugged terrain and far distances pose significant transportation and infrastructural challenges. However, with a $376,000 grant from the US Department of Housing, Penn State University seeks to alleviate Alaska’s housing crisis by 3D printing affordable concrete homes.

At the core of this project lies a collaboration between Penn State’s Additive Construction Laboratory (AddConLab) and the Xtreme Habitats Institute (XHI), a non-profit organization dedicated to exploring innovative technologies that may enhance living conditions for Alaskan residents. Partnering with XHI, Penn State is deploying a mobile 3D concrete printer that promises to address various challenges unique to Alaska’s housing landscape. This system will enable rapid construction while reducing costs, and will utilize local materials to help mitigate environmental impact and enhance sustainability.
