Building with 3D printers has matured rapidly in recent years, as advances in technology and material science allow for grander and more ambitious designs. The potential uses are also increasingly varied, from affordable housing to a planned NASA base on the Moon.
Most 3D-printed structures are built using concrete or other pourable, cementitious substances that are cheap, reliable and durable — although, almost invariably, with a hefty carbon footprint attached. But a nascent development in the field may offer a more sustainable approach: 3D printing with earth. (Read more)
