Berkeley research team led by Ronald Rael, associate professor of architecture, will unveil today (Friday, March 6) the first and largest powder-based 3-D-printed cement structure built to date. The debut of this groundbreaking project is a demonstration of the architectural potential of 3-D printing. It will close the fifth annual Berkeley Circus, which celebrates the research and accomplishments of the College of Environmental Design (CED) community.
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.
Bloom is a precise 3-D-printed cement polymer structure that overcomes many of the previous limitations to 3-D-printed architecture. Such limitations include the speed and cost of production as well as aesthetics and practical applications.
