Abstract: The 3D printer made in America was introduced to Hebei Provincial Institute of Cartography in September, 2015. By utilizing its assorted printing software and engaging the technical staff in repeated practice,a set of technological process of production in accord with the reality of China were developed. It succeeds in resolving the series of tough problems, such as transforming the model of the fundamental geographic information data into that of the 3D data, the editing of the 3D elevation models and the designing of the 3D symbols. The technology integrates the cartographic techniques presented in varied software, such as 3ds Max, ArcGIS and Global Mapper, characterized by strong practicability, maneuverability and high value of popularizing. The technology covers hill shading topographic maps, digital orthophoto maps, thematic maps, sand table models and so on. The maps printed by 3D printers are characterized by bright colors making the elevation models real and direct, free color combination rich in variety, impressive accuracy, ability to receive multisource data and high productivity.
