Optimization of Fused Deposition Modeling 3D Print Machining Parameters Using Hybrid Taguchi Approach

The 3D printing method (additive manufacturing) is one of the manufacturing technologies for producing parts with faster, more flexible, and relatively lower-cost procedures compared to conventional methods, one of which is fused deposition modeling (FDM). A primary challenge often encountered during the 3D printing process using the FDM method is the engineers’ lack of knowledge in optimizing three machining parameters (nozzle temperature, printing speed, and infill pattern) to enhance the mechanical properties and quality characteristics of FDM-type 3D printed parts. The hybrid Taguchi method was employed in this paper to obtain optimal printing parameters. The L9 (33) orthogonal array layout was selected and utilized to obtain optimal printing response results. The outcomes indicated that the maximum tensile test achieved was 20.7 MPa with a combination of parameters: nozzle temperature of 280 °C, printing speed of 40 mm/s, and a grid infill pattern.
