3D Concrete

A UC Berkeley research team led by architecture professor Ronald Rael worked on putting together the first and largest powder-based 3-D-printed cement structure built to date.

Thailand-based Siam Research and Innovation and a graduate student research team composed of Kent Wilson, Alex Schofield, Sofia Anastassiou, and Yina Dong worked to develop the elegant, curving structure made from 840 precisely printed bricks.

The Bloom pavilion was at UC Berkeley's College of Environmental Design for students and fqacuality to admire. It drew a lot of attention while on campus.

Ronald Rael is an associate professor of architecture at Berkeley's College of Environmental Design and co-founder of Emerging Objects - a 3D printing think tank that recently developed a brick that can cool buildings using only water. He worked with Thailand-based Siam Research and Innovation and a graduate student research team composed of Kent Wilson, Alex Schofield, Sofia Anastassiou and Yina Dong to develop the elegant, curving structure made from 840 precisely printed bricks.

Bloom is a free-standing pavilion constructed entirely through 3D printed technology. It stands at nine feet tall, has a footprint of 12 feet X 12 feet, and consists of a total of 840 customized blocks that are connected through steel hardware.

After its official unveiling, the Bloom Pavilion was disassembled and shipped to Siam Research and Innovation in Thailand to be displayed for several months before touring the world.

3D printing technology has advanced by leaps and bounds over the past decade. Today's advanced 3D printers can produce functional tools, full-sized furniture, automobiles, and even entire buildings. Bloom is a precise 3D-printed cement polymer structure that overcomes many of the previous limitations to 3D-printed architecture, such as the speed and cost of production as well as aesthetics and practical applications.
