[Explanation] When it comes to imitation of cultural relics, most people think of fraud, but it is not.
After being authorized, the "imitation master" establishes a true, accurate and complete three-dimensional data file of the cultural relics. The imitations can also be displayed instead of the real ones, so that people can appreciate the cultural relics while protecting them from damage.
Recently, the reporter came to Gansu Bolijiang 3D Printing Technology Co., Ltd. to explore the "imitation master" of cultural relics.
In the office, 3D modeler Wang Yuntong operates a computer to process the stele text.
He told reporters that because 3D modeling is extremely important for imitation of cultural relics, the scanned data must be processed in detail.

During the scanning process, because the material of the stone stele is not deep enough to capture the details, we need to carry out manual intervention. The principle must be based on the real object, and the sculpture must not be used casually. (This) makes the (model) more vivid and more vivid. Image.
[Explanation] Every day, Wang Yuntong builds a 3D model of cultural relics on the computer, and deepens the text on the model to ensure that the imitation can show the text content.
In the office next door, Pan Bingqing, wearing a white coat, screened and filtered more than ten kinds of Gobi sands, and then mixed them with a certain proportion of curing agent to provide raw materials for the imitation of cultural relics.

The materials used for making cultural relics in sand molds are, for example, some silver sand and some Yinchuan sand.
The most important thing is that the sand composition and content in different places are not the same. Through sand printing, cultural and creative products are made, and cultural relics are imitated.
[Explanation] Pan Bingqing said frankly that at present, most imitations of cultural relics use resin, but due to hardness limitations, large-scale cultural relic models are fragile, and sand can make up for this defect.

Compared with resin, resin is generally a polymer material, which is relatively brittle and is not conducive to long-term protection (utilization). The situation is different for sand molds. The first hardness is higher, and the second has better weather resistance. , So that it can be stored for a longer time.
[Explanation] Sun Keyuan, assistant to the general manager of Gansu Bolijiang 3D Printing Technology Co., Ltd., said that they usually cooperate with museums, and imitation products are not circulated in the market and are only for tourists to visit.

In the current situation, most of the cultural relics are kept under very strict conditions, which makes it impossible to go out for exhibitions or exhibitions in museums. Then it needs some substitutes to be displayed to tourists to achieve the display effect.
[Explanation] Sun Keyuan told reporters that in order to prevent the leakage of cultural relics data to the greatest extent, they have independent server storage, and employees need to submit applications at various levels to obtain relevant data and carry out cultural relics copying.
