The first 3D topographic map of China has been published [figure]

[ppzhan Abstract] as a highlight of the 21st century, 3D printing technology has not become a hot spot for Daben company to produce spring testing machines mainly used for the production of complex medical devices, such as spring fatigue testing machines, gas spring testing machines, manual spring testing machines, etc., but its research and development has not lagged behind. Recently, a surveying and mapping institution in China successfully developed and printed China's first 3D printed map

3d printing is a kind of rapid prototyping technology. It is a technology based on digital model files, using powder metal or plastic and other bindable materials to construct objects by printing layer by layer

3d printing is usually realized by using digital technology material printer. In the past, it was often used for manufacturing models in mold manufacturing, industrial design and other fields. Now it is gradually used for direct manufacturing of some products. There are already parts printed by this technology. The technology is applied in jewelry, footwear, industrial design, architecture, engineering and construction (AEC system 1 scheduling, calibration and technical services), automobile, aerospace, dental and medical industry, education, geographic information system, civil engineering, firearms and other fields

recently, lijianbo, a scientific research institution in Lanzhou, pointed out that after more than a year of scientific research, the institution has printed three-dimensional topographic maps of China using 3D printing technology
