医学3D打印数据接口的网络化应用分析

Analysis on network application of medical 3-dimensional printing data access

目的 :研究医学3D打印技术相关的数据接口,分析其在网络化条件下的应用前景。方法 :根据三维计算机辅助设计(computer aided design,CAD)系统之间以及CAD系统与快速成型系统之间的数据接口标准,利用实例分析产品模型数据交换标准(standard for the exchange of product model data,STEP)、STL文件格式和相应的网络化技术在医学3D打印领域的应用模式。结果:将STEP的实体描述与可扩展标记语言(extensible markup language,XML)的网络适应性特点相结合,实现了异地异构CAD系统和快速成型系统间的数据交换。结论:STEP和XML技术为医学3D打印业务的拓展和深化提供了新的思路和手段。

Objective To research a medical 3-dimensional printing data access and analyze its network-based application. Methods According to standards of data access among 3-dimensional CAD systems and between CAD system and rapid prototyping system, the application patterns of STEP and STL file format and related network technologies were analyzed in medical 3-dimensional printing field with real world entity. Results With STEP entity representation and XML network features, data exchanges between heterogeneous CAD systems and RP systems in different districts were performed. Conclusion STEP standards and XML technology can provide ideas and methods for network application of medical 3- dimentsional printing.
