Stl Model Of Rp System Of Dividing And Combining Research

Most Rapid Prototyping (RP) systems have the following disadvantages: bulky, expensive, and requiring a large cost. So the advanced technology and its system are restricted to be applied. According to market requirements, a new RP system, which is small volume and low price, is developed and pushed into the market, even into office and home. It is the point of this paper.This paper is focused on the study of dividing and combining module based on STL model, which enhances the function of existent RP system and makes it to be able to manufacture big parts or several small parts at one time.Dividing technology based on STL model and its necessity is studied in this paper. Rectification and topology base on STL model is researched, too. The contour information is obtained by using slice technology; the Delaunay triangular meshes are generated by using Delaunay triangulation algorithm and conglutinate precision of divided models is insured by using precise orientation technique. In addition, triangle scan is accomplished based on Delaunay triangulation algorithm.Combining technology based on STL model and its necessity is studied in this paper and the combining function is completed. Every model can be adjusted dynamically by using OpenGL technology. Precision and facileness of this software is unproved by using orientation optimization algorithm.On experiment, machining scale of RP system is extended, manufacturing efficiency is improved and material expenditure is reduced by using this commercial software. The facileness and intellectualization of this software is considered adequately and it is proved to be useful.
