MIT researchers explore 3D printing to reduce concrete's carbon footprint
What happened
Concrete is the second most widely used construction material globally, with the United States consuming about 260 million cubic yards annually. Globally, over 4 billion tons are produced each year, and the material is responsible for 8% of global CO2 emissions due to its manufacturing process and scale of use. Researchers have discovered a novel way to 3D print concrete that is more efficient and uses less material. However, current large-scale commercial printers face challenges with complex designs, such as sharp turns or hollow shapes.

Why it matters
The high volume of concrete production makes it a major contributor to global carbon emissions. The potential of 3D printing to precisely place material and reduce waste could significantly lower the industry's carbon footprint. This technology aims to mitigate the environmental impact associated with the chemical processes required for concrete manufacture.
