逆向工程是一种通过数字化现有零件，创建计算机模型，然后使用它来制造组件来构建物理零件的计算机辅助设计（CAD）模型的方法。当数字化部件将通过诸如立体光刻设备（SLA）和选择性激光烧结设备（SLS）等的快速原型机器制造时，也不需要构建数字化部件的CAD模型。这可以通过所提出的新方法来实现，该方法可以直接从数字化的零件数据构建STL文件（快速成型机的事实上的文件格式）。此外，STL文件可以根据用户的判断进行大量的数据缩减。
Reverse engineering is a methodology for constructing computer-aided design (CAD) models of physical parts by digitising an existing part, creating a computer model and then using it to manufacture the component. When a digitised part is to be manufactured by means of rapid prototyping machines such as stereolithography apparatus (SLA) and selective laser sintering equipment (SLS), etc., it is nor necessary to construct the CAD model of a digitised part. This can be achieved by the proposed novel method which can construct an STL file (the de facto file format for rapid prototyping machines) directly from digitised part data. Furthermore, the STL file can be constructed with a significant data reduction at the users' discretion.
