Moon topographies are just a sampling of the many models that can be 3D printed. Topographical modeling has been around since 1752. Advances in modern technology including 3D printing has exponentially increased our ability to enhance geoscience learning and research. NASA uses models like these to help scientists better understand the Earth and its solar system. This tactile approach to learning enables those without sight to experience the solar system like never before. To learn more, see our Topographical Models page.
