Optimasi Multirespon pada Proses 3D Printing Material ABS dengan Metode Taguchi-PCR Topsis

Abstract

[Title: Multi response Optimazion In 3D Printing ABS Materials With Taguchi-PCR Topsis Method] The use of 3D printing technology, commonly referred to as additive manufacturing, is increasingly widespread as a rapid prototyping method. Acrylonitrile butadiene styrene (ABS) is one type of material whose use is quite massive in 3D printing technology. In this study, nine experiments were carried out using the experimental design method orthogonal arrays L9 ( 3 3 ), and three process parameters were used, namely nozzle temperature, base plate/bed temperature, and orientation, as well as with three levels of variation for each process parameter (230oC, 240oC, 250oC, 90oC, 100oC, 110oC, 0o, 45o, 90o). This study aimed to find the optimal process parameters for the processing response time, mechanical properties of flexural strength, and dimensional accuracy. Thus, a combination of the Taguchi and PCR-TOPSIS methods was used to solve the multiresponse problem. Based on the results of ANOVA analysis, the parameter with the level that produces the most optimal combined response is located in the third condition specimen (that is, the nozzle temperature value is 230°C; the base plate/bed temperature is 110°C, and the printing orientation direction is 90°). The results of the PCR-Topsis analysis on three process parameters shows that the parameters that have the highest influence in sequence are orientation at 33%, bed temperature at 28%, and nozzle temperature at 18%.
