Analisis Pengaruh Parameter Proses 3D Printing Filamen Epa-Cf Terhadap Kekuatan Tarik Pada Pembuatan Steering Wheel Mobil Listrik Urban Titen EV

Abstract

Additive Manufacturing (AM) is a printing technology that can convert 3D CAD (Computer Aided Design) models into real objects. The process of making an object is carried out by adding material layer by layer which is combined into one complete object. This research aims to analyze the influence of process parameters in 3D printing using ePA-CF filament on tensile strength. The research focus considers the possibility of using ePA-CF material with increased strength and the combination of each parameter that can provide maximum tensile strength. In data processing, the Taguchi method was used to design the experiment, and analysis of variance (ANOVA) was used to determine the contribution of each parameter. Based on the results of experiments and analysis, it is known that the nozzle temperature parameter has a significant influence on the tensile strength of the ePA-CF filament and print speed does not have a significant influence on the tensile strength of the ePA-CF. The contribution of each parameter to tensile strength is as follows: 76.05% (Extruder Temperature), 1.61% (layer height). Optimal parameters are determined at Nozzle Temperature 260°C and Print speed 50 mm/s. The findings of this research provide a better understanding of the influence of process parameters in 3D printing and can serve as a guide in the production of 3D printed products.
