基于逆向工程和3D打印的水泵叶轮快速重建方法

Rapid Reconstruction of Pump Impeller Based on Reverse Engineering and 3D Printing

以某电子水泵叶轮为例,基于逆向工程及3D打印技术,介绍水泵叶轮快速重建的全过程。介绍了由Handyscan 3D激光扫描仪和VXelements 3D数据采集软件组成的点云数据获取系统、描述了Ceomagic Studio逆向软件对点云数据处理的方法、CATIA软件对实体的三维数字化模型的重建过程等,最后获得符合精度要求的数据模型并通过FORTUS 360mc 3D打印机完成实物打印的过程。研究结果对其他种类的产品具有参考价值,逆向工程作为吸收先进技术的一种手段,可以基于原有产品进行分析和再创新,对于缩短新产品研发周期、提高设计水平具有重要意义。

Taking an electronic pump impeller as an example, this paper introduces the whole process of rapid reconstruction of the pump impeller based on reverse engineering and 3D printing technology. This paper introduces the point cloud data acquisition system composed of Handyscan 3D laser scanner and VXelements 3D data acquisition software, describes the method of point cloud data processing by Ceomagic Studio reverse software, and the reconstruction process of entity 3D digital model by CATIA software, etc. Finally, the data model that meets the precision requirements is obtained and the process of physical printing is completed by 3D printer. The research results have reference value for other kinds of products. As a means of absorbing advanced technology, reverse engineering can analyze and re-innovate the original products, which is of great significance for shortening the research and development cycle of new products and improving the design level.
