The application of advanced 3D printer technology makes it easy for designers and concept development teams to produce components and concept models using a 3D printer. 3D Printing is a tool that can process the creation of a series of objects by placing thin layers that are formed sequentially according to the desired shape. FDM is a 3D Printing technique for printing products using filament as a material. FDM (Fused Deposition Modeling) technology is a technology for creating 3D objects. 3D printing is often referred to as the newest technology that can change the world. However, FDM technology has a weakness because this technology uses a building process per layer, making the resulting surface appear to have lines that indicate the boundaries between layers, thereby affecting the roughness of the specimen surface. In this discussion, the researcher uses the Taguchi Method experimental design with the L9 Orthogonal Array design plan with three factors and three levels. Signal to Noise Ratio SNR analysis to determine optimal parameters for Dimensional Accuracy and Surface Roughness of ABS filament. The process parameters that will be used in this research are nozzle temperature (°C), print speed (mm/s), bed temperature (°C). The optimal parameters in terms of accuracy are nozzle temperature (237°C), print speed (42mm). /s), Bed Temperature (92°C). And in surface roughness the optimal parameters are Nozzle Temperature (240°C), Print Speed (45mm/s), Bed Temperature (105°C).
