Objective To fabricate the cranial bone replica with selective laser sintering by laminated object manufacturing.Methods MINICS8.1 software was used to process the CT data of the cranial bones. The filtration of CT data, binarization, bone's contour extraction and vectorization were performed in order. The CT data was converted to STL format. The STL file was checked and repaired with Magics RP5.41, and inputted into the rapid apparatus HLP-450. The 3D stereo-temporal bone physical model was built layer by layer. Results Physical model of the cranial bones was obtained. The dimensions of the model were in agreement with the cranial bones. Conclusion The accuracy of the cranial bones model can meet with the maxillofacial surgery requirements.
