Prosthetic socket plays the most important role in lower limb prosthesis. The conventional
fabrication process of prosthetic socket is labor intensive and time-consuming. The
application of additive manufacturing technology may greatly simplify the process. One of
the main concerns on the reliability of 3D printed prosthetic socket is its structural strength
due to the various 3D printing parameters that may influence the strength of 3D printed
products. Furthermore, most of the previous studies focused on single parameter and the
effect on socket strength. Thus, this study aimed to examine the optimization of fused
deposition modeling printing parameter of 3D printed prosthetic socket in term of strength,
fabrication time and weight. Three FDM printing parameters were studied which included
layer height, nozzle diameter and infill percentage. The data was analyzed using Taguchi
and PCR-TOPSIS methods. Based on the result, it was concluded that the most effective
combination of printing parameter is 1.0 mm nozzle diameter, 0.48 mm layer height and
30% infill percentage. In addition, infill percentage shown the highest influence towards the
responsive values followed by layer height and nozzle diameter.
