3D printing is a cutting-edge technology that holds tremendous promise for scientific research and education. For Earth and planetary scientists, the advantages of using such technology include the ability to elucidate spatially complex geological structures and processes that are otherwise difficult to visualize using 2D media such as computer screens or paper. Concepts around earthquake faults, volcanoes, and trilobites often become more approachable for non-experts when 3D printed because they can be handheld and sometimes physically manipulated. The generation of 3D printed models, including experimental Lab samples (e.g. synthetic rocks), is not only a way to create hands-on educational activities, but a powerful tool to present our data and numerical models to a broader audience. This session focuses on 3D printing techniques and examples of 3D printed models used to enhance educational experiences. Presentations that focus on 3D printing technology, pedagogy, or both are welcome.
