Influence Factors Analysis of the 3D Printing Rapid Prototyping System Using Entropy Method and System Dynamics Model

This paper mainly discusses the influence factors of 3D printing rapid prototyping system using entropy weight method and system dynamics model. Firstly, through survey we find the influence factors, next using entropy weight method to calculate index weight, then we use SD method to simulation and draw the causal diagram and loop diagram. Finally, we analyze the various influencing factors and find the key factors. The results shows that improving the advanced level of molding equipment and enlarged material R&D efforts are of important guiding significance for largely improving efficiency of forming and promoting the popularization of 3D printing rapid prototyping system.
