Additive manufacturing (AM) is revolutionizing production processes by enabling the creation of complex geometries with high precision and reduced material waste. Fused deposition modelling is most extensively used method of additive manufacturing to build the parts. This study investigates the influence of key process parameters like layer thickness, printing speed, infill density, infill style, and printing temperature on the printing time, dimensional accuracy and material consumption of 3D-printed parts using PC-ABS with graphene. Specimen were prepared according to “L27” orthogonal array. The Taguchi method was employed to identify the optimal settings that enhance dimensional accuracy while minimizing material usage and printing time. Taguchi method also used to determine most influential factor for performance parameters.
