3D printed architecture is here. 260 million surfaces in 1 month

English: A 3D-printed version of the Penrose T...

3.2 meters tall 6.8 meters long by 3.2 meters wide room printed completely by a 3D printer. It has 260 million surfaces. Weights in at 11 tons of sandstone but amazingly it only took 1 month to print and a single day to assemble. Hansmeyer and Dillenburger, both computational architects at the Swiss Federal Institute of Technology‘s architecture department in Zurich, wrote algorithms to completely design the complex geometry of the 16 square meter (170 sq ft) room . Dubbed “Digital Grotesque,” their modern take on a medieval grotto was made with a new type of 3D printed sandstone, infused with a hardening resin to increase its structural stability. To print out the sandstone parts that made the room, the duo used a massive Voxeljet 3D printer, about the size of a large room. “It can print a single piece that weighs 12 tons, yet at a layer resolution of 0.13 millimeters,” says Hansmeyer. “This combination of scale and resolution seemed unreal to us at first.”

The scale of machines, high material costs and the structural weakness of 3D printed materials is the reason why architects have up to now used 3D printing technology only to make prototypes or small scale models. The sand-printing technology the duo employed finds use in industrial applications, but with the addition of their innovative methods, it can now be used to create huge prefabricated sandstone bricks strong enough to build with.

The room with 260 million surfaces: 3D printed architecture is here.
