Rapid Prototyping Technology in the Three Dimensional Model of Hierarchical Processing

Abstract:

Rapid prototyping technology can generate parts directly from the three-dimensional CAD entity data, hierarchical algorithm is a key link in rapid prototyping manufacture. In this paper, mainly used a hierarchical approach in RP equipment,for the study aimed at three commonly hierarchical algorithm (hierarchical algorithm based on STL model, direct sliced of CAD models, Smart Slice based on STL model) by Perspective, trying to provide a reference for the stratification algorithm of RP system by comparison of the three tiered approach,This paper argues that the Smart slicing algorithm based on STL model is more accurate stratification algorithm

Conclusion In this paper I list the advantages and disadvantages of three kinds of methods respectively based on STL model, CAD directly layering and smart slice algorithm, finally compare the optimal algorithm is smart slice algorithm based on STL model. And getting the following conclusion: (1) the STL file layered approach is still the mainstream of RP layering technology in the short term. (2) CAD directly layering method has the advantages of correctiing data process is simple, but still need a standard file format for the application. (3) smart slice algorithm based on STL model of high precision parts, reduces the memory consumption because of using adjacency list data structure, and the calculation process is simple , so it has good development prospect.
