机械零件快速成型中STL模型优化方法研究

Study on The Optimization Method of STL Model in Rapid Prototyping Machine Parts

针对同一机械零件的不同局部表面精度要求的不同,提出一种STL模型的局部优化方法。利用该方法一方面可以去除冗余的STL网格,另一方面可以对机械零件要求的关键部位进行STL模型的局部加密。实验证明通过该方法,保证了机械零件的精度并在此前提下提高了机械零件快速成型制造的效率。

For the same mechanical parts of the different requirements of different local surface accuracy, propose a local optimization method for STL model. Using this method, On the one hand can remove the re- dundant STL grid, On the other hand, STL model has a key position requirement of mechanical parts can be partial encryption. Experiments show that by this method, to ensure the accuracy of the mechanical parts and in this context to improve the mechanical efficiency of rapid prototyping parts.
