Abstract : This study aims to find the optimal parameters to produce good dimensional accuracy and maximum bending strength in the FDM 3D printing using a Cu-PLA filament. The parameters used in this research are nozzle temperature, layer height, and infill pattern with 2 levels for each parameter. The experimental design used the Taguchi L4 method (23). The specimens were printed according to the ASTM D790 standard using the REXYZ A1 3D printer machine. From the results of the calculation of the average S
