Researchers at Northwestern University have devised a technique to 3-D print soft rubber-like materials out of ink composed primarily of extraterrestrial soil. Using a biologically derived binder to hold the soil particles together, the team demonstrated that their unique method can 3-D print tools, building blocks, and other structures.
