PRINTING SPACE: 3D PRINTING OF DIGITAL TERRAIN MODELS FOR ENHANCED STUDENT COMPREHENSION AND EDUCATIONAL OUTREACH

Data visualization is a core component of every scientific project; however generation of physical models has previously depended on very expensive or labor intensive molding, sculpting or laser sintering techniques. Physical models have the advantage of providing not only visual but tactile modes of inspection, allowing easier visual inspection as well as access to the visually challenged. Recent advances in 3D printing technology have created low cost systems capable of translating three dimensional shape and terrain elevation models into physical models. Low cost commercially available 3D printers are capable of using data from topographical maps, RADAR and SONAR data, altimetry and digital terrain models and turning them into accurate, handleable 3D models out of multiple materials in a matter of hours. The resultant models provide not only study materials for lunar and planetary terrains as well as small space bodies but can also allow generation of libraries of physical objects accessible to the visually handicapped, and allow the addition of space sciences to the roster of accessible science curricular material
