My mind is officially blown. We’ve seen 3D printed dresses and guns and now Winsun new materials, a company based in China, has managed to print 10 full-sized eco-friendly houses in just one day. Measuring 600 square feet and costing under $5000 to build, each “house” was created in a couple of hours entirely out of recycled construction and industrial waste with an enormous 3D printer that extrudes a mix of high-grade cement and glass fiber material, layer by layer, similar to traditional rapid prototyping processes. Amazing that it is SO fast and low cost. One immediate use I can think of, right off the bat, is after a natural disaster, dwellings could be pumped out immediately to house displaced persons. We are inundated with the bad news of the world but in some ways the future has already arrived. Now, if we can just figure out how to print a new 3D earth after we’ve wrecked this one, we could relax a bit.
