摘要:

随着3D打印的快速发展,其在口腔颅颌面外科的应用越来越广泛,3D打印个性化生产改变了传统依靠手工成型的落后模式,满足了不同患者的使用需求。但目前对于颅颌面修复体制作用3D打印金属粉末的性能要求并无明确规范,不利于产业的长久发展。本文对颅颌面修复体制作用3D打印金属粉末的制备工艺(气雾化法、等离子体旋转电极雾化法、射频等离子体球化法)以及3D打印成型工艺(选区激光熔化、电子束选区熔化、激光近净成形)进行了介绍,并且根据制备工艺及成型工艺特点总结了颅颌面修复体制作用3D打印金属粉末的性能要求。

Abstract:

With the rapid development of 3D printing, it is widely used in the field of cranio-maxillofacial surgery. Through the individualized production of 3D printing, the backward mode of traditional production relying on manual shaping has been changed to meet the needs of different patients. However, as no clear specification exists for the performance requirements of 3D printing metal powder for cranio-maxillofacial surgery, its long-term development is not feasible. In this paper, the preparation technologies of 3D printing metal powder for cranio-maxillofacial prostheses (i.e., gas atomization, rotating electrode atomization, and radio frequency plasma spheroidization) and 3D printing forming technologies (i.e., selective laser melting, electron beam selective melting, and laser-engineered net shaping) are introduced. The performance requirements of 3D printing metal powder for cranio-maxillofacial prostheses are then summarized according to the characteristics of the preparation and forming technologies described.

Key words: 3D printing, cranio-maxillofacial prosthesis, metal powder, performance characteristics
