基于逆向工程与快速成型的假体设计和制造

Design and manufacture of prosthesis based on reverse engineering and RP technology

在传统的义耳制作中,通常采用人工雕刻自身软肋骨来完成,其精度及制作效率取决于雕刻师的技巧、经验及审美水平。文章介绍了一种基于激光扫描和快速成形技术制作假体的方法。以义耳设计和制造为例,采用激光扫描仪获取耳朵的轮廓数据,并通过逆向软件生成曲面,最后在快速成型系统中加工出模型。研究结果表明,该集成制造方法可以快速制作出准确逼真的造型,从而为手术的规划提供直接的参考。

The traditional method to manufacture the auricular prosthesis is based on sculpting on the tissue site. The accuracy and efficiency of prosthesis produced by conventional method absolutely depend on the skill, experience and aesthetic level. An integrated method of laser scanner and rapid prototyping technology for prosthesis fabrication is presented in this paper. As an example related to the design and manufacture of auricular prosthesis, the laser surface digitizer is used to capture the data of ear firstly, and then convert the data into curved surface by reverse software; Finally, the model of ear by rapid prototyping system is manufactured. The research results have shown that the integrated method can produce exact-fit prosthesis quickly, the model may provide direct reference facilitate for the surgeon planning.
