碩士 === 東海大學 === 工業設計學系 === 95 === The main purpose of this research is to find the optimization rapid prototyping parameters of Fused Deposition Modeling (FDM) machine by using Taguchi method in order to improve the quality of FDM product. Traditional full-factorial experiments are not practical because it costs a lot of time, outlays and man-power. Therefore, this study uses Taguchi method to set up a parameter experiment. It uses orthogonal array table which can decrease the number of experiment times to set up experiments. Finally, this study analyzes experiment data to find the optimized factors of experiment groups.It processes settled experiments to test and verify the results through producing actual examples. In this research, it firstly finds out what are the parameters that will affect the quality of RP product and uses SolidWorks 2004 software to draw a 3D CAD model for testing. The 3D model will be transferred into STL file and exports to RP machine for finding out factors and levels. This study uses Tacguchi orthogonal array to execute experiments. After the experiment, it measures the final product which is produced by RP machine in order to get practical data. Finally, this study proceeds optimized parameters confirmation experiments in order to testify the result. It is found that the optimized parameters is efficacious because the product proceed by optimized parameters data has more accurate dimensions than the default parameter. The FDM machine is settled as following items. “Support Style: basic” “Part Surface: Best horizontal quality” “Part Interior Style: Solid-normal” “Layer Resolution: 0.254mm” “Position: Center” “Direction: Transverse” Under this kind of conditions, this type of machine can get the most precise quality. It is the results get from the effort of this research.
