Abstract
Rapid Prototyping (RP) technique is widely used to industrial and medical products including biomedical instruments. The clinical applications of the RP technique to model surgery are reported more favorably in some papers. However, the model dimensions with high precision have been described as technically difficult. In this paper, we developed the bone biomechanical experiments using three dimensionally acrylic and trabecular resin model from Computed-Tomography data to evaluate the applicability of the RP technique to bone fracture estimation. The results show that careful preoperative planning and experience are important factors in achieving successful results.
