This issue primarily arises from the absence of standardized settings for printing parameters, particularly in academic environments such as the Industrial Engineering Laboratory at UIN Sunan Kalijaga. Such inconsistencies lead to increased finishing time and cost, as well as reduced prototype quality. This study aims to optimize three key parameters?layer height, print speed, and nozzle temperature?in order to minimize the surface roughness of prints made from Polylactic Acid (PLA) material. The Taguchi method is employed for its efficiency in determining the optimal parameter combination with a minimal number of experiments. The experimental design utilizes an L9 Orthogonal Array with nine combinations of trials. The surface roughness results are analyzed using the Signal-to-Noise (S/N) ratio and Analysis of Variance (ANOVA) to identify the significance of each parameter. The findings indicate that the optimal parameter combination consists of a 0.15 mm layer height, 40 mm/s print speed, and 205°C nozzle temperature. Among these, layer height has the most dominant influence on surface roughness, contributing 95.15%. This study provides practical guidelines for determining 3D printing parameters to achieve smoother, more consistent, and efficient print surfaces, particularly in academic learning and laboratory settings PB - UIN SUNAN KALIJAGA YOGYAKARTA KW - FDM KW - Kekasaran Permukaan KW - Layer Height KW - Nozzle Temperature KW - Parameter Cetak KW - Print Speed KW - Taguchi KW - 3D Printing M1 - skripsi TI - OPTIMASI PARAMETER PROSES PENCETAKAN 3D FILAMENT PLA UNTUK MENGURANGI KEKASARAN PERMUKAAN DENGAN METODE TAGUCHI AV - restricted EP - 114 ER -
