China News Agency, Hangzhou, June 12 (Xie Panpan Wu Yalan Ke Yineng) Let the cultural relics "live", let the cultural relics "go out", the removable 3D printed digital grottoes were unveiled at Zhejiang University on the 12th. On the same day, the special exhibition "Wei Feng Tang Tang: A Hundred Years of Memory and Reproduction of Yungang Grottoes" hosted by Zhejiang University and Shanxi Provincial Bureau of Cultural Relics opened at the Museum of Art and Archaeology of Zhejiang University.

Yungang Grottoes are the first large-scale grotto temples built by royal excavation after Buddhism was introduced to China between the two Hans. The Harmony style is called the "Yungang Mode" by the Buddhist archaeological community and represents the outstanding level of world architecture and sculpture art in the 5th century AD.

  This exhibition is divided into four units, selected 112 pieces (sets) of cultural relics such as stone statues, inscriptions, ceramic utensils, and building components collected by the Yungang Grottoes Research Institute. Many exhibits are exhibited to the public for the first time. The exhibits also include a removable 3D printed digital grotto jointly completed by the Cultural Heritage Research Institute of Zhejiang University and the Yungang Grottoes Research Institute.

  The 3D printed digital grotto is located in the fourth unit of the exhibition. It is the 12th cave of Yungang restored with digital 1:1. Cave 12 is also known as "Music Cave", in which carved images of Heaven and Man and Chinese and foreign musical instruments show the earliest "Court Symphony Orchestra" in ancient China.

  From August 2016, the Cultural Heritage Research Institute of Zhejiang University and Yungang Grottoes Research Institute cooperated to collect high-fidelity 3D digital data for Cave 12. After that, through photogrammetric calculation and manual interactive three-dimensional processing, the cooperation team established a high-fidelity color three-dimensional model of Cave 12.

  After the 3D printed polymer material was cured, the art team of Yungang Grottoes Research Institute painted the replication cave with mineral pigments according to the ancient method, and it took 8 months to complete the reproduction.

  Li Zhirong, deputy dean of the Cultural Heritage Research Institute of Zhejiang University, believes that this work is to some extent "rebuilding" a grotto.
