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/N ratio, the best dimensional accuracy when
using variations of nozzle temperature 220 oC, layer height 0.3 mm, and
infill pattern lines. While the maximum bending strength when using a
nozzle temperature variation of 240 oC, layer height of 0.4 mm, and the
octet infill pattern. Each factor contributes to dimension accuracy in per
cent as accuracy is 9.16 %, nozzle temperature, 4.01 % layer height, and
19.56 % infill pattern. In other words, all factors did not have a significant
contribution to the accuracy. Meanwhile, the contribution of each
parameter to the bending strength is nozzle temperature 57.66 %, layer
height 15.22 %, and infill pattern 0.44 %.
