11 Mar 2015 Cement structure shows architectural potential of 3D printing Supplier: Siam Cement Group More Siam Cement Group details
Professor Ronald Rael led the Bloom project photo: Tom Levy The first and largest powder-based 3D-printed cement structure has been built at a US university.
Created to demonstrate the architectural potential of 3D printing, the freestanding pavilion – Bloom – is composed of 840 customised blocks, measures roughly 12ft by 12ft, and is 9ft high.
The University of California, Berkeley research team was led by Ronald Rael, associate professor of architecture, who developed a new type of iron oxide-free Portland cement polymer formulation which enabled the 3D printing.
“We 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,” said Rael. “This project is the genesis of a realistic, marketable process with the potential to transform the way we think about building a structure.”
Bloom was unveiled on 6 March and closed the fifth annual Berkeley Circus, an event which celebrates the research and accomplishments of the university’s College of Environmental Design community.
It will now be disassembled and shipped to Siam Research and Innovation in Thailand. The company, a research and development division of Siam Cement Group, provided funding and collaborative support for the project, and will put the structure on display for several months, after which it will travel to various locations around the world.
Siam Cement Group provided the Portland cement, while additional support and materials were provided by Emerging Objects, a startup company co-founded by Rael and Virginia San Fratello, and Entropy Resins.
