A symbrachydactyly is a genetic problem which also synonym as a person with fingerless condition. The patients will have difficulties in daily activities such as to hold an item. To ease the constraints, a customized and patient-specific prosthetic hand is needed with a minimum cost. This project covers the designing process for the prosthetic hand, including computational analysis. Parametric study on the different thickness of the palm cover was conducted to evaluate the performance of the product. Then, the prosthetic hand is fabricated using 3D printing technology. The simulation study suggested that the 5mm thickness of the palm cover was sufficient to the product. The resulting maximum stress variation and total displacement were the indicator in proposing the optimum design.
