prosthetic socket. Materials and Methods This study proposed a 3D-printed socket with three built-in tiny air bladders integrated within the interface between the liner and socket and electronically managed by a pressure and volume control system. A pseudo-artificial residual limb was fabricated to mimic the transtibial residual limb. The interface pressure in the 3D-printed socket was evaluated using F-socket transducers during inflation and deflation of the air bladders in the stance phase through universal tensile machine load. Results Based on the statistical analysis, the highest significant pressure reduction (P < 0.05) was 5.71%, which was recorded at the posterior region, and 4.68% (P < 0.05) at the medial region during posterior and medial air bladders inflation, respectively. Conclusion Peak pressures were reduced at the lateral tibia condyle, tibia tuberosity, tibia crest, anterior distal end of tibia, fibula head, distal end of fibula, medial femoral condyle, lateral femur
