Researchers develop sustainable concrete substitute for 3D printing Construction 3D Printing
According to Oregon State University (OSU), researchers have developed a quick-setting, environmentally friendly alternative to concrete they hope can one day be used to rapidly 3D print homes and infrastructure. The new clay-based material developed by Devin Roach, Nicolas Gonsalves, and collaborators at Oregon State cures as it’s being extruded from the printer, thanks to its acrylamide-based binding agent, which undergoes a chemical reaction known as frontal polymerization. The material can even be printed across unsupported gaps, such as the top edge of an opening for a door or window.
