This study explores the impact of process parameters and infill patterns, namely zig-zag and gyroid, on Fused Deposition Modelling (FDM) 3D printing. The research investigates how variations in critical parameters like nozzle temperature, print speed, and bed temperature, coupled with different infill patterns, influence the mechanical performance of printed specimens. Tensile and flexural tests were conducted to assess strength, stiffness, and resilience. Results indicate that infill pattern selection significantly affects the mechanical properties, with the zig-zag pattern outperforming the gyroid pattern. The study also highlights the intricate interplay between process parameters and mechanical characteristics, identifying optimized combinations to enhance the overall performance of 3D-printed objects. This research contributes valuable insights into the symbiotic relationship between process parameters, infill patterns, and mechanical performance in FDM 3D printing.
