在地质工程教学中，需要讲授地质体的三维形态与结构特征，而传统的语言描述、图片展示、录影介绍不够直观明了。为充分满足课堂直观教学需求，基于3D数字扫描、3D数字重建、3D打印技术，对野外地质体结构进行扫描、重建和打印，用重建的3D数字模型和3D打印模型表征野外地质体，用于课堂教学的实体展示。%Abatract:Geological engineering teachings include three- dimensional morphological and structure charac-teristics of geologic body.However,the traditional teaching methods,such as language description,image display, video introduces,can`t match with current demand.3D scan,3D digital reconstruction and 3D printing technolo-gies are introduced to rebuild geologic body’s digital model and print entity model used in class.
