It is proposed to develop a simple and clear language for use as a digital interface in Solid Free-Form Fabrication. This language is called "SIF" for "Solid Interchange Format" inspired by CIF, the Caltech Intermediate Form for LSI layout description. The role of SIF would be to describe the ideal solid part desired, in a fabrication-process-independent way. It is further proposed to create a foundation for some of the key tools needed with such an exchange language, in particular, a robust slicing tool to create 2.5D layers needed for process planning, as well as checker programs that will verify that the shape specified in the SIF file is indeed a closed solid, has the required topological and geometric properties, and specifies only realizable features containing certain minimum feature sizes and separations. Finally, it is proposed to develop test structures of various kinds that will test the robustness of analysis and conversion tools working from SIF input for different SFF fabrication processes and to monitor the quality of individual production runs.

建议开发一种简单明了的语言，用于固体自由曲面制造中的数字接口。这种语言被称为“SIF”，意思是“Solid Interchange Format”，灵感来自于CIF，这是加州理工学院用于LSI版图描述的中间格式。SIF的作用是以一种与制造过程无关的方式描述所需的理想固体部件。还建议为这种交换语言所需的一些关键工具创建基础，特别是创建工艺规划所需的2.5D层的健壮切片工具，以及将验证在SIF文件中指定的形状确实是封闭实体、具有所需的拓扑和几何属性并且仅指定包含某些最小特征尺寸和间隔的可实现特征的检查程序。最后，建议开发各种测试结构，以测试根据不同SFF制造工艺的SIF输入工作的分析和转换工具的稳健性，并监控各个生产运行的质量。
