The present invention relates to a method and system for detecting the repeatability of STL format model files and belongs to the computer technical field. The method comprises the following steps that: an STL format model file is acquired; an equal-boundary ratio model having the same boundary dimension ratio with the STL format model file exists in a model library is judged, wherein the boundary dimension ratio is the ratio of the boundary dimensions of the envelope hexahedron of the model; and if the volume ratio of the equal-boundary ratio model is equal to the volume ratio of the STL format model file, the STL format model file is a repeated model, wherein the volume ratio is the ratio of the volume of the model to the volume of the envelope hexahedron. The method has the advantages of simple calculation process and high detection accuracy, and can be widely applied to the three-dimensional model processing technical field. 本发明涉及种检测STL格式模型文件重复性的方法及系统，属于计算机技术领域。其中，检测方法包括：获取STL格式模型文件；判断模型库中是否存在与STL格式模型文件具有
