The dozens of gold masks unearthed at the Sanxingdui Site had all suffered from severe deformation and had not been effectively protected or restored for a long time. To explore effective methods for their conservation and restoration, digital technologies such as 3D modeling, digital measurement, simulation comparison, and 3D printing were fully integrated into the restoration process. This approach not only resolved the challenge of matching the gold masks with bronze head statues to support archaeological research, but also ensured that the correction process followed the principles of “original craftsmanship” and “authenticity”. In addition, custom-made preventive support devices contributed significantly to the preservation and exhibition of the gold masks. The integration of digital technologies throughout the entire process of research, conservation and display of the gold masks has expanded new pathways for cultural heritage conservation.
