一种新的快速成形层面数据文件格式

为解决快速成形中原有层面数据文件格式(如CLI和SLC)的存储信息不完备、存取效率不高且不具备扩展性的缺点,提出了一种新型的快速成形层面数据文件格式———ZIF格式.它基于树状信息块结构,能存储快速成形加工过程中所需要的全部层面数据与工艺参数信息,并且具备实时随机检索文件中任意一层的层面数据的能力,该格式能内嵌STL文件信息来满足加工过程中通过浏览实体模型优化工艺参数的需要,并通过自定义参数的方式来传输各种特定工艺专有的加工参数,此外,该格式能不断扩展新的信息块以支持未来工艺的新要求.同时叙述了ZIF文件的格式规范、存取方法及其应用.

A new layer data file format for rapid prototyping

A new layer data file format,ZIF format,was proposed to improve the original layer data file formats,such as SLC and CLI formats,for rapid prototyping.The new format was based on the tree-structure of information block.The total information(layer data,technical parameters and STL solid information) were stored in only one file.With the advantage of the index of information blocks,the data of every layer were accessed in real-time.An information block for user-defined parameters would support the storage of special data of every rapid prototyping technique.By means of new information blocks,the file format would be extended for the future.The criterion,access method and applications of ZIF format were also discussed.
