A group of students in Barcelona--Anusha Arunkumar, Kunaljit Singh Chadha, and Yessica Gabriela Mendez Sierra--are working to decode what they say is a “nano scale understanding of material behavior to shape, control and design landforms” via 3D printing processes. They hope that the “small interventions through deposition of a binder into an abundant natural material” they make, essentially printing in sand, “can direct nature’s forces to control how landforms are shaped.” The project, named In:Sand, examined and tested materials from molded corn starch to sprinkled corn starch to wax and oil for use as binding agents.
