Industry Watch: Digital Guardianship: AI and 3D Technology Usher in a New Era for Ancient Jade Relic Protection


In the brilliant tapestry of Chinese civilization, ancient jade, with its unique warm luster and profound cultural connotations, carries thousands of years of historical memory. However, these precious ancient jade relics face severe protection challenges due to natural erosion, human damage, and the passage of time. In recent years, with the rapid development of technology, Artificial Intelligence (AI) and 3D scanning and printing technologies are opening up new avenues for the protection of ancient jade relics, ushering in a new era of 'digital guardianship'.

Technology Empowerment: From 'Salvage Protection' to 'Preventive Protection'


Traditional ancient jade relic protection has largely focused on 'salvage protection', which involves repairing artifacts after damage has occurred. This approach is often time-consuming and labor-intensive, and it is difficult to fully restore the original appearance of the artifact. Today, the concept of 'preventive protection', centered on AI and 3D technology, is gradually becoming mainstream.


Taking the National Museum of China as an example, according to Professor Wang Ming, director of its cultural relics protection technology department, the museum launched a key scientific research project called 'The Charm of Jade – Digital Archiving and Disease Prediction' in 2022. This project utilizes high-precision 3D scanners to collect data at millimeter or even micrometer levels for over 3,000 important ancient jade artifacts in its collection, including famous Hongshan Culture jade dragons and Liangzhu Culture jade cong. This data not only builds precise 3D models of the artifacts but also captures subtle cracks, changes in infiltration color, and other information on their surfaces.


“We use AI algorithms to deep learn from this massive amount of data to establish a database of ancient jade disease models,” Professor Wang Ming explained. “This allows us to predict the aging trends and probability of disease occurrence in ancient jade under different temperature, humidity, and light conditions, thereby taking intervention measures in advance to minimize potential risks.” According to the project team's latest report, early identification of cultural relic diseases has increased by approximately 40% through AI prediction, providing a scientific basis for developing more precise protection plans.

3D Printing: Innovation in Restoration and Replication


In addition to preventive protection, 3D printing technology also shows great potential in the restoration and replication of ancient jade. Traditional ancient jade restoration requires extremely high standards for materials and craftsmanship, and it is often irreversible. 3D printing technology, however, can provide a non-destructive, reversible, and highly reproducible solution.


At the Zhejiang Provincial Institute of Cultural Relics and Archaeology, archaeologists successfully used 3D printing technology to restore a damaged jade bi unearthed from the Liangzhu site. Through 3D scanning of the fragments, its original form was accurately restored, and the missing parts were printed using special polymer materials for filling. Li Hua, deputy director of the institute, stated: “3D printing not only significantly shortens the restoration cycle, from traditional weeks to a few days, but more importantly, it preserves the integrity of the artifact to the greatest extent, leaving more possibilities for future research.”


Furthermore, the application of 3D printing in cultural relic replication is also becoming increasingly widespread. High-fidelity 3D printed replicas can be used not only for exhibitions and education but also effectively reduce the risk of exhibiting precious originals. For example, the Palace Museum plans to launch a batch of high-precision 3D printed jade replicas in 2024 for public viewing and touching in interactive experience zones, greatly enhancing the breadth and depth of cultural dissemination.

Challenges and Prospects: Interdisciplinary Collaboration is Key


Although AI and 3D technologies have brought revolutionary changes to the protection of ancient jade relics, challenges still exist. Issues such as standardization of data collection, generalization capabilities of AI models, durability and fidelity of 3D printing materials still need to be further overcome. In addition, the high cost of equipment and the lack of professional talent are also significant obstacles to promoting these technologies.


“In the future, the protection of ancient jade relics will emphasize interdisciplinary cooperation even more,” stressed Zhang Wei, director of the Jade Research Committee of the China Cultural Relics Society. “We need the close collaboration of cultural relic experts, material scientists, computer engineers, artificial intelligence experts, and other forces to jointly promote technological innovation and application. Only in this way can these treasures, which carry the memory of the Chinese nation, flourish with even more brilliant light under the guardianship of the digital age and be passed down for generations.”


The journey of digital guardianship for ancient jade has just begun, but the enormous potential it demonstrates undoubtedly paints a hopeful future for us. The integration of technology and culture will allow ancient jade to be reborn and passed down forever.
