3D Printing with Local Soil: The Next Step for the Construction Industry

Researchers from Texas A&M University are developing a promising sustainable, adobe-like building material that can be created from local soil and extruded from a 3D printer to make a robust structure, according to a new report recently presented at the American Chemical Society Fall 2020 Virtual Meeting & Expo.

 .

There are two huge challenges currently facing the construction industry: the need for more sustainable infrastructure and the need to fix deteriorating infrastructure. For more than a century, concrete has been the go-to construction material for buildings and infrastructure.

 .

Unfortunately, the production of concrete has an extensive carbon footprint, as well as a high degree of waste and a final product that cannot be recycled.

 .

To address the sustainability issues facing the construction industry, some scientists have been researching solutions related to additive manufacturing, or 3D printing, which involves extruding subsequent layers of a quickly-solidifying material. There […]
