Print This: UC Berkeley Uses 3D Printers to Construct a First-Ever Cement Pavilion

Perhaps you remember the day when printers, requiring only lowly paper and toner, simply produced documents. Now we’re well on our way into the Jetsonian age: today 3D printers, supplied with a sophisticated cement, can produce a house.

That, in fact, is precisely what’s happening at UC Berkeley today as a team headed by associate professor of architecture Ronald Rael unveils his architectural creation “Bloom”—billed as the first and largest powder-based 3D-printed cement structure to date.

Berkeley Architect Aims to Transform the World—One Outlandish Project at a Time
