Chinanews.com, Lanzhou, April 2 (Ai Qinglong Gaozhan) With the development of economy and society, cultural relics "hidden in deep boudoirs" approached public life through TV programs, cultural and creative products, and cultural relics collection. More and more sought after.
However, due to harsh maintenance conditions or inconvenient movement, some cultural relics cannot be accessed by the public.
Therefore, the imitation and display of precious cultural relics came into being.
Recently, a reporter from Chinanews.com 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 details of a 3D model of a stone monument.
Wang Yuntong said that because 3D modeling is extremely important for the imitation of cultural relics, they will first go to the location of the cultural relics to collect data such as height, shape, and color, and aggregate them into a 3D model.
Wang Yuntong said that due to the influence of texts and materials, during the scanning process of the machine, there are situations where the details are not captured enough. This requires them to manually intervene in the 3D model according to the actual object, and process the details such as text and color depth to allow It is more vivid and vivid.
As we all know, materials are an important material basis for the development of 3D printing technology.
Commonly used materials include nylon glass fiber, durable nylon, gypsum, aluminum, titanium alloy, stainless steel, silver-plated, gold-plated, rubber, etc.
In this company, the raw material for imitation of cultural relics is actually sand.
“The sand surface has insufficient adhesion and poor bonding performance. Through continuous experimentation, printable raw sand is formed.” Pan Bingqing, an R&D engineer of the company, said that they will screen and filter more than ten kinds of Gobi sands and mix them with a certain amount. After waiting for half a day with the proportion of curing agent, raw sand of different shades will be formed. After that, they will provide suitable sand materials for it according to the cultural material and 3D model.
In the factory, workers operate the machine to input 3D data, select the corresponding sand and soil, and the machine starts to run.
The robotic arm moved back and forth, and the scanning platform lit up with red dots from time to time... About 2 hours later, the imitation Buddha image emerged from the sand.
“When it comes to imitation of cultural relics, most people think of fakes, but it’s not the case.” said Sun Keyuan, assistant to the general manager of Gansu Bolijiang 3D Printing Technology Co., Ltd.. Complete three-dimensional data files, imitation products can also be displayed instead of real products, so that people can appreciate the "cultural relics" while protecting the original objects from damage.
"Imitation is a means of displaying cultural relics, but it does not mean that everything can be imitated." Sun Keyuan said frankly that at present, subject to realistic conditions, it is impossible to imitate the types of cultural relics such as books, calligraphy and painting, and ceramics.
It is reported that cultural relics "imitation masters" usually cooperate with museums, and imitation products do not circulate in the market and go directly to the museum for tourists to visit.
Imitations of cultural relics such as bronze horse-drawn carriage, painted lacquered wooden dove, toad-shaped bronze inkstone, Mingxiang wheel copper pagoda, and Beiliang statue stone pagoda were "born" from here, starting a parade, allowing more people to witness the charm of cultural relics.
