摘要
Technology of 3D-Printer based on fused deposition material has developed intensively with varying qualities.However, default setting of printing process parameters provided by the manufacturer in some cases does not guarantee quality (dimension error and strength) of the printed part, since there are several process parameters that need to be considered.A 3D-Printer with polylactic acid filament material has been applied in this study.A specimen standard of ASTM D638 Type IV has been used as a tensile strength and dimension error test to represent printed part quality.Three printing process parameters: layer thickness (0.05, 0.1 and 0.15 mm), temperatures (195, 200 and 205°C) and raster angles (-45°, 0° and 60°) have been optimized using Taguchi and Response Surface Methods.Test was carried out to find the highest tensile strength and the lowest dimension error based on the optimum parameter setting and validated them with experiment and default setting.Quality of printed part obtained by optimum parameter setting of RSM [0.05 mm, 199.8 o C, 45.1 o ] showed better than that by Taguchi [0.15 mm, 195 o C, 0 o ] and default setting [0.1 mm, 200 o C, 0.0 o ].In addition, tensile strength of printed part mostly was affected by layer thickness, while dimension error was caused by raster angle.
