3D Printing with Powered Concrete

Mar-14-15 A new 3D printing technology that uses dry cement powder instead of standard wet cement could change the way architects and builders approach building with cement.

Developed at Berkeley University, the technology is based on a special formulation of iron oxide-free Portland cement mixed with fibers and polymers that was developed by Associate Professor of Architecture Ronald Rael. A 3D printer prints out the dry cement power in thin layers that are then wetted and left to harden, reducing waste (because no molds are required) and allowing for the creation of lightweight and complex structures.

The team recently demonstrated their technology's capabilities with the Bloom pavilion, which was built with 840 customized 3D-printed bricks.
