Cement polymer, wood, chocolate, paper, salt, nylon and acrylic are just a few materials that Emerging Objects are 3D printing. A group focused on innovations in 3D printing architecture and building components, some of these shapes and patterns are quite nice. I see some of these as art or sculpture. They would make fantastic dividing walls in modern homes. Maybe even exteriors walls using the correct materials. Take a few minuets and visit their site, pretty cool things happening.
