UC Berkeley unveils first-of-its-kind 3-D-printed cement structure
A UC Berkeley research team led by Ronald Rael, associate professor of architecture, developed the first and largest powder-based 3-D-printed cement structure built to date. According to Rael, they “are mixing polymers with cement and fibers to produce very strong, lightweight, high-resolution parts on readily available equipment; it’s a very precise, yet frugal technique.”
The freestanding pavilion, “Bloom,” is 9 feet high and has a footprint that measures about 12 feet by 12 feet. It is composed of 840 customized blocks that were 3-D-printed using a new type of iron oxide-free Portland cement polymer formulation developed by Rael.
