This room, conceived and created by architects Michael Hansmeyer and Benjamin Dillenburger, might not be the world's first 3-D printed structure. But the design, which they call Digital Grotesque, is almost definitely the most ambitious: computer algorithms designed the 3.2-meter-tall, 16-square-meter room, which has a whopping 260 million (!) surfaces. And instead of being made of plastic (3-D printing's go-to material), it's printed from sand. Plus, it looks incredible--much more like a real-life, human-built room than any other 3-D printed structure, albeit one that's half Roman temple, half H.R. Giger nightmare.
"We think it's the world's first 3-D printed room," Hansmeyer tells us in an email, "in the sense that it's fully structural and has a complex surface, it's self-supporting, and it's massive (11 tons)."
