Analisa Parameter Printing Speed, Bed Temperature, Dan Infill Density Dalam Proses Cetak 3D Printing Terhadap Kekuatan Impak Filamen Berbahan Polyethylene Terephthalate Glycol (PETG) Menggunakan Metode Taguchi

Abstract

3D printing is the process of creating physical objects from digital models by successively stacking layers of materials to form the desired object. Bed Temperature, Printing Speed, and infill density are some of the problems that cause imperfect printing processes such as warping, strigging, layer separation, prints not sticking to the bed and ghosting. This research uses the Taguchi method. Taguchi method is a method by analyzing the results of a process and determining factors about a process or population based on an analysis of the information contained in the sample or population and then comparing the measurement results with the desired output specifications/characteristics. This research can be seen that factor C (Infill Density) has the highest contribution to the impact strength of PETG (Polyethylene Terephalate Glycol) filaments, then factor A (printing speed), and in the last place is factor B (Bed Temperature). Then it can be concluded that the results of calculations and impact testing on specimens with the taguchi method obtained the most influential parameter on impact strength is Infill Density, based on the analysis of calculations and tests, the level of each parameter of the most optimum combination is: Printing speed 35 mm/s, bed temperature 85 ºC, infill density 90% with an impact strength test value of 95917.86 J/m.
