Pengaruh Variasi Parameter 3D Printing pada Bahan Campuran Pla dan Titanium Terhadap Uji Kekuatan Tarik

Abstract

3D printing is a technology that can print an object from a digital file (CAD) into an object that has volume and mass. The principle of 3D printing is to create objects using the layer by layer method, namely by adding layers of material which are then overwritten by the next layer to make a product. This research was conducted to determine the tensile strength of the specimens by collecting data using the taguchi method, namely L9(3)4. Tensile testing was carried out with a computer universal testing machine and analyzed with ANOVA. The results of the analysis of variance (ANOVA) stated that the most influential parameter was the nozzle temperature with a contribution value of 66.09%. Variations in print parameters in this study include nozzle temperature (230˚C, 235 ˚C and 240˚C), bed temperature (90˚C, 95˚C and 100˚C), print speed (30 mm/s, 35 mm /s, and 40 mm/s) and layer height (0.2 mm; 0.25 mm; and 0.3 mm). The highest tensile test results were 12.22 MPa at nozzle temperature variations of 240˚C, layer height of 0.3 mm, print speed of 35 mm/s and bed temperature of 90˚C.
