为了简化股骨肿瘤切除手术的操作，提高切除部位的准确性，根据患者计算机断层(CT)扫描和三维重建等临床影像学资料为股骨肿瘤切除手术设计了一种定位模板。利用自主研发的选区激光熔化(SLM)快速成型设备Dimetal-280进行了316 L不锈钢粉末的正交实验工艺研究，获得优化参数，并用该参数加工所设计的手术模板，加工速度快，成型后外形良好，尺寸精度高，在临床手术中获得成功应用，为个性化医学植入体以及辅助器械的高性能、自动化加工开辟了一种新方法。

In order to simplify the thighbone tumor surgery and improve the accuracy of the areas to be cut, a kind of surgery orienting model for the surgery operation is designed according to the scanning data of computer tomography (CT) and the three-dimensional reconstruction image. By using the Dimetal-280 selective laser melting rapid prototyping system, the surgery orienting model of 316 L stainless steel is made through orthogonal experiment for processing parameter optimization. The technology of direct manufacturing of surgery orienting model by selective laser melting(SLM) shows obvious superiority with high speed, precise profile and good accuracy in size comparing with the traditional ones. The model has been well applied in a real surgery operation for thighbone replacement operation. The successful development of the model provides a new method for the automatic manufacture of customized implants and surgery model, and will build a foundation for more clinical applications in the future.
