Optimasi Variasi Material Nozzel dengan Bahan PLA+ Menggunakan Metode Taguchi terhadap Kualitas Hasil Cetak 3D Printer Jenis FDM

Abstract

The AM technology commonly used is Fused Deposition Modeling (FDM). FDM is a production process using polymer material that is melted and ejected from a nozzle to form a 3D product. The nozzle has an important role in extruding the filament. In this research process, the Taguchi method is used to determine the Orthognal Array used as a guide in conducting experiments. The Signal Noise To Ratio is used as a study method to look for ranking values of the variables that affect the print surface roughness and dimensional accuracy. The Anet A8 V2 3D printer with PLA+ filament is a tool used in research. From the results of calculations using the Signal to Noise Ratio which produces the best print quality, the surface roughness of the top and bottom is the nozzle diameter (0.4 mm). While the best print quality for the side surface roughness is and layer height (0.2 mm). The best print quality for dimensional accuracy is the nozzle diameter (0.6 mm). The optimization of brass material compared to stainless steel is currently the same, both in terms of roughness and dimensions, the material is a channel for filaments from solid to semi-solid.
