Engineering’s Elias Ali talks about 3D-printers and sustainability

Florida barn will be the world’s largest 3D-printed building
AxiosElias Ali, assistant professor of civil and environmental engineering, discussed the effort to create a standard type of construction material that reduces the amount of cement in concrete, replacing it with bio-inspired materials to make it sustainable. “The biggest concern is, as long as the 3D-printers are using the same amount of cement, or even larger amounts of cement, we end up having the same [CO2] impact as conventional building,” he said. “The less cement you use, the less carbon dioxide emissions that you’re going to produce.”
