Making of an artificial leg takes longer term up to two months because of the repetition of the test walking and the socket shape modification. In this study, we developed the Immediate Fitting Socket (IFS) system which enables immediate test walking and shape modeling for casting. IFS are constructed of an outer shell and a particle containing bag, whose rigidity can be controlled by the applied negative pressure. The three point load test was performed to evaluate the strength of the particle containing bag. The effect of the surface material, particle size and negative pressure were examined. The particle bag consists of two materials with different elasticity, 0.5 mm diameter particles and -650 mmHg negative pressure possessed rigidity equivalent to polypropylene. The shape modeling berformance was evaluated by measuring the circumferences of the models from a plaster imitation and three amputees. The modeling error was less than 0.5% in plaster imitation, and less than 6% in amputees. The polymer socket casted from the model was successfully utilized by the amputee.
