Abstract: In order to improve the speed and accuracy of designing and manufacturing of individ-uaized bones, shorten the waiting time of patients and advance the extent of shape matching, a new molding method of artificial bones which needs no surface reconstruction, is introduced to shape the model of individuaized bones directly by rapid prototyping, that is ,to convert the data of slice images to the data of the contours of cross－sections and make the solid model by rapid prototyping.The shape of the model can be modified after it is manufactured. The results show that the method has the advantages of rapidness and accurateness which are very important for individuaized bones.
