A 15-year old Chinese immigrant, adopted as a baby by the founder of MapQuest, is using her adult-sized ambition to use 3D-printing to help more kids get an education in Madagascar. Maggie Grout’s nonprofit is called “Thinking Huts” and they are fundraising to break ground on a series of modular, honeycomb-shaped schools, powered by solar panels, which would be the world’s first 3D-printed schoolhouses. Hundreds of millions of children don’t have schools to attend around the world, and Grout feels one of the best ways to solve the problem is by bringing down the construction costs of schoolhouses. The initial pilot Thinking Hut in Madagascar is expected to cost $20,000, and in a recent interview at the Smithsonian, Grout details how, as well as being half the cost of traditional construction methods, 3D-printed buildings become cheaper when the project is scaled. In other words the first house may cost $20,000, but the more houses that are built, the cheaper they become.
