cqvip:Currently,3D printing of the character dolls is a very practical application for the average person.But the model of doll which can be obtained is static so the posture of the doll is single.On the other hand,the modification of the model is very difficult to non-professions.This paper proposes an rapid generation method of character doll with rotatable limbs,which is through adding the sphere joint to the doll's model automatically.After the model is segmented by drawing a line interactively,the sphere joint is created based on the segmentation boundary through entity modeling method.Lastly the two models of the doll and the joint are composited and printed.Some doll's model are tested on the FDM(Fused Deposition Modeling)3D printer using this process.The results are more interesting and the efficiency has been greatly improved compared with modifying the model manually.
