Optimization of process parameters to improve mechanical properties of fused deposition method using taguchi method

Additive manufacturing, specifically Fused Deposition Modeling, is a 3D printing technology that creates parts by layering liquid solid material. However, 3D printed parts may not have the same surface finish or functional strength as traditional methods. Researchers used the Taguchi method to study the impact of factors like layer thickness, nozzle design, filling percentage, build time, and surface roughness on 3D printed parts. The study found that infill percentage had the most significant impact on surface roughness and tensile strength, followed by layer thickness and other process factors.
