[Explanation] Recently, the reporter discovered that on the sixth floor of the City Media Plaza located in the West Coast New District of Qingdao, Shandong, there was a replica version of the "Third Yungang Grottoes" with the same size and even the traces of weathering.
How is it done?
How is it placed here?
With many questions, the reporter went to the scene to interview relevant personnel.
[Explanation] According to Shi Hongze, deputy general manager of Qingdao Media Development Co., Ltd., the replica cave is 17.9 meters long, 13.6 meters wide, and 10 meters high. There are magnificent and beautifully carved statues, as well as complete grottoes. The world's first large-scale cultural relics reproduction project using 3D printing technology, the overall reproduction process is very complicated.
[Concurrent] Shi Hongze, Deputy General Manager of Qingdao Media Development Co., Ltd.
It took two years to complete the project after scheme demonstration, data collection, data processing, 3D printing, structure design and construction, printed parts assembly, light source design and installation, sandblasting and coloring.
During the implementation of the project, the Yungang Grottoes Research Institute and Zhejiang University jointly tackled key problems, and adopted a working method combining 3D laser scanning technology and multi-image 3D reconstruction to reconstruct the high-fidelity color 3D model of Cave No. 3 of Yungang Grottoes with high fidelity .
Then, through the introduction of domestic self-developed high-precision 3D printers, all the details of the cultural relics are copied through computer 3D laser scanning technology combined with 3D printing casting technology, so as to achieve high-precision restoration of cultural relics materials and color textures.
[Explanation] Because the third cave has a large volume, it needs to be divided into 842 pieces for 3D printing during the duplication process, and the surface texture is reconstructed using a three-dimensional surface coloring process to ensure that it is consistent with the texture of the body. Finally, mechanical assembly and foam filling are used. , patchwork treatment, sandblasting and coloring and other processes have formed a replica of the original size and high fidelity grottoes.
During this process, the team also encountered many difficulties.
[Concurrent] Shi Hongze, Deputy General Manager of Qingdao Media Development Co., Ltd.
Because it is the first large-scale printing in the world, it encountered many technical difficulties.
Including color reproduction, printing machinery, and construction conditions, we have overcome them one by one.
In order to implement the printing project, we specially designed and manufactured 24 special printers with a height of 2 meters and 8 meters. The overall printing process took five and a half months.
The 842 pieces (replicas) were transported from the printing factory in Shenzhen to Qingdao, and they faced a new problem.
It is such a large volume, how can it be transported to the sixth floor?
When we were building, there was a wall that was not built, and we left it out. After the printed body arrived in the square, it was transported from the wall to the inside by a crane, and then the wall was sealed.
During the construction process, it is also because it is not a pure construction process, and it is difficult for workers to achieve refinement and reduction in the assembly process. We specially hired experts and scholars from the Yungang Grottoes Research Institute. The main creative team has gone through 26 days. Splicing, perfectly installed successfully.
It is difficult to reflect the material of the yellow sandstone that prints the appearance of the Buddha statue.
We adopted the method of combining technology and history, used the sandstone of Yungang Grottoes, and sprayed it on the surface after technical reconciliation, that is to say, the appearance of the Buddha statue we see now, these sandstones are the original ecology of Yungang Grottoes of sandstone.
[Explanation] Shi Hongze said that making the immovable Yungang Grottoes "live" and reproducing them in other cities through technical means will allow visitors to appreciate the art of the cave's shape, architecture, and weathering.
[Same period] Xu Congjie, general manager of Xinhua Bookstore Co., Ltd., Huangdao District, Qingdao
Our Xinhua Bookstore in Huangdao District, relying on the 3D Yungang Grottoes statues created by the group as the core, has established the Qingdao West Coast New Area as a traditional art museum.
While inheriting the culture, we also set up the Yungang Grottoes Art Museum, so that children can learn about Yungang Grottoes art and 3D printing technology on the basis of learning traditional culture, so that children can visit Yungang Grottoes art at home, Move the traditional culture classroom to the museum, learn from the tour, study from the study, and deeply root the traditional culture in the hearts of the students.
Since its establishment, we have received a total of more than 60,000 domestic and foreign research students, and more than 120 schools of various types.
