From afar, the woven "bricks" at Cos's eighth Salone del Mobile installation, a collaboration with architecture firm Mamou-Mani, look as if they're woven from straw. Nope. The cone-like shapes are actually 3D-printed out of fully compostable plastic made using renewable resources. To bring the structures to life, they created open-source software inspired by silkworms' cocoons. Set against the architecture of the 16th-century Palazzo Isimbardi, the exhibit feels extra futuristic. We've officially caught the 3D-printing fever, and it's time to put our money where our mouths are by buying things like a seashell-inspired lamp 3D-printed from corn‑based materials.
