Research On Fused Deposition Rapid Prototyping Technology Optimization Based On TRIZ Theory

With manufacturing globalization of the market and people becomes more and more higher todemand for the product, so vital to the survival of enterprises is to shorten design cycle about theproduct and reduce the investment risk of new product, so as to be satisfy to people’s demand forproduct by continuously. Rapid prototyping technology is generated in this case. Currently, FDM isone of the most widely used that is rapid prototyping technology. Therefore, in order to meeting theneeds of manufacturing, using the theory of TRIZ that its tools and methods, it plays a specialimportant significance on the optimization to FDM.The major task of this paper is to optimize the FDM technology through the TRIZ theory toobtains the optimization program on FDM, and analyzes the optimization program by further, sooptimal design results are obtained.The main research work of this paper is as follows:1. To FDM process, forming precision and forming efficiency is as a problem to put forward,so as to determine the contradiction problems restricting the FDM technology evolution. Due to theanalysis of different problems have different solutions and to further research which is based onTRIZ theory, so this paper is make use of the innovation principle of utility methods to solve; Andanalyzing the technology and the object contradictions, eventually identified as forming precisionand forming efficiency is the problem which is the technical contradictions.2. The forming precision and forming efficiency are transformed into the general engineeringparameters that are composed of the contradiction matrix, then through the Pro-Techniques5.0which is one of solving the technical contradiction problem that its software to find to solve thecontradictory between the technical innovation of principle; According to the analysis of thecorresponding innovation principle to determine the optimum design scheme of FDM.3. According to studying the proposed optimum design scheme, with an average effect andforming the surface of the parts to the forming efficiency and forming precision targets to build themathematical model of the listed functions expression; And in view of the connecting rod parts as the research object, using VC++and MATLAB software to analyze two mathematics model byrespectively, obtained the forming direction and the thickness of stratification is two importantfactors to influence the forming efficiency and forming precision.4. Proposed to multi-objective optimization the forming precision and forming efficiency toestablish about multi-objective optimization, multi-objective optimization mathematical model. Andanalysis of intelligent optimization algorithm is discussed, and finally uses the PSO for solvingmulti-objective optimization problems, finally concluded that connecting rod parts forming theoptimal molding direction and layer thickness. The forming efficiency and forming precision ofparts have been greatly improved through the optimization program.After the researching, it obtains an inclusion that the TRIZ theory is applied to optimize theFDM technology which can gets a program by rapidly and high-quality，it can effectively improvesthe forming efficiency and forming precision parts, thus achieve technology optimization.
