The use of manufacturing additives or commonly known as 3D
Printing is increasingly widespread. The type of additive
manufacturing that is often used is FDM (Fused Deposition
Modeling). The most frequently used filament for prototyping and
research is PLA (Poly Lactide Acid) type filament. This research will
use multiresponse optimization, namely Taguchi-grey. So that later
in this study will use 9 conditions with 3 parameters and 3 levels.
The parameters used were orientation (0 °, 45 °, 90 °), nozzle
temperature (190 °C, 200 °C, 220 °C), and bed temperature (0 °C,
30 °C, 60 °C). The purpose of this study was to find the most optimal
parameters based on response time, dimensional accuracy and
tensile strength. Based on analysis using Taguchi-grey, ANOVA
results show that the most significant contribution is nozzle
temperature (51%) and orientation (42%). From ANOVA, it can be
seen that the most optimal condition is condition 6 which has been
printed, with orientation of 45°, nozzle temperature of 220°C and
bed temperature of 0°C.
