Supported by 3D printing technology, the movable replica of a cave in the Yungang Grottoes, a 1,500-year-old UNESCO World Heritage site, has passed experts' tests this week.

　　由3D打印作为技术支持，活动的1500年历史联合国教科文组织世界遗产云冈石窟已经在本周通过专家的测试

　　研究所所长张卓称：“这一石窟体现了鱼缸最高级别的艺术形式”.石窟中雕刻着演奏中外乐器的石像

　　The research team collected high precision 3D data and kept errors to within 2 millimeters. The main body of the replica was made of resinous material, and the printing process took around six months.

　　研究所书记了高精度的3D数据并且将错误数值控制在2毫米以内.复制品的主体使用树脂材料支撑，上色过程花费了6个月的时间

　　"We plan to color it with mineral pigments before the end of this year. In this way, the replica will maintain its original size, texture and color," Zhang said.

　　张卓称：“我们计划在今年年末之前用矿物干颜料为石像上色.用这种方式，复制品可以白柳原始尺寸，质地和颜色”
