| Summary: | Malaysia’s need for 200,000 prosthetic legs demands efficient production processes and three-dimensional (3D) printing can potentially address this. Despite the advantages of pin-lock sockets in below-knee prosthetics, research on their application in trans femoral amputations remains limited. This study designs and compares conventional and pinlockprosthetic leg sockets for transfemoral amputees using 3D scanning, modeling, and printing. Conventional and pinlock transfemoral leg sockets at 6 mm were designed using 3-Matic software. Their biomechanical properties were testedvia ISO 10328 compression testing on the Instron 8874 machine. Results indicated that pin-lock sockets had higher average Young’s modulus (36.27%) and yield strength (43.53%) compared to conventional designs. However, ultimate compressive strength (UCS) showed no statistically significant difference between the designs (p > 0.05). Practical benefits like user stability and comfort might favor the pin-lock design. Future research should consider larger samplesizes and additional gait phases for comprehensive evaluation. © 2024, IEICES/Kyushu University. All rights reserved.
