3D打印技术在龙门石窟金刚经洞修复中的应用
Application of the 3D printing technology in the restoration of the Vajra Sutra Cave in Longmen Grottoes
摘要
Abstract
In order to alleviate the developmental problems due to water damage,microorganisms and other diseases caused by the local collapse of the Vajra Sutra Cave,the 3D printing technology was used to repair collapsed areas:a photosensitive resin was selected as the printing material for restored parts with a hollow structure;the light field and temperature field simulation design for the restored parts reduced the solar radiation intensity into the cave to 50%-56%that of direct sunlight,and the amplitude of temperature fluctuation was reduced from 6.6℃to 1.9℃;S8801 was used to coat the inner and outer surfaces with the result that the main performance retention rates of S8801 after aging experiments were greater than 90%,and the basalt fiber and glass fiber were used to enhance the inner surface.After multiple rainfall observations,it was found that the problem of rainwater backtracking in the Vajra Sutra Cave in Longmen Grottoes had been effectively alleviated.This work laid a foundation for the combination of 3D printing technology and restoration of immovable stone cultural relics.关键词
