In general, the 3 D printed medical models are made based on virtual digital models obtained from machines such as the computed tomography scanner. However, due to the limited accuracy of CT scanning technology, which is usually 1 millimeter, there are differences between scanned results and the real structure. Besides, the collected data can hardly be printed directly because of some errors in the model. In this paper, we present a general and efficient procedure to process the digital skull data to make the printed structures meet the requirements of anatomy education, which combines the use of five 3 D manipulation tools and the procedure can be finished within 6 hours. Then the model is printed and compared with the cadaveric skull from frontal, left, right and anterior views respectively. The printed model can describe the correct structure and details of the skull clearly, which can be considered as a good alternative to the cadaveric skull. The manipulation procedure presented in this study is an easily available and cost-effective way to obtain a printed skull model from the original CT data, which has a considerable economic and social benefit for the medical education. The steps of the data processing can be performed easily. The cost for the 3 D printed model is also low. Outcomes of this study can be applied widely in processing skull data.

通常，基于从诸如计算机断层摄影扫描仪的机器获得的虚拟数字模型来制作3D打印的医学模型。但是，由于CT扫描技术的精度有限（通常为1毫米），因此扫描结果与实际结构之间存在差异。此外，由于模型中的某些错误，很难直接打印收集到的数据。在本文中，我们提出了一种通用且有效的程序来处理数字头骨数据，以使打印的结构满足解剖学教育的要求，该程序结合了五个3D操作工具的使用，并且该程序可以在6小时内完成。然后打印模型，并分别从前，左，右和前视图与尸体头骨进行比较。印刷的模型可以清楚地描述头骨的正确结构和细节，可以认为它是尸体头骨的不错选择。本研究中介绍的操作程序是从原始CT数据获得打印的颅骨模型的简便易行且具有成本效益的方式，这对医学教育具有可观的经济和社会效益。数据处理的步骤可以轻松执行。3D打印模型的成本也很低。这项研究的结果可广泛应用于处理颅骨数据。这对医学教育具有可观的经济和社会效益。数据处理的步骤可以轻松执行。3D打印模型的成本也很低。这项研究的结果可广泛应用于处理颅骨数据。这对医学教育具有可观的经济和社会效益。数据处理的步骤可以轻松执行。3D打印模型的成本也很低。这项研究的结果可广泛应用于处理颅骨数据。
