选择性抑制烧结（SIS）是一种新的快速成型方法，可在逐层制造的基础上构建零件。SIS的工作原理是通过烧结将粉末颗粒加入零件的主体中，并通过烧结抑制某些选定的粉末区域。在这项研究中，统计工具被应用于改善SIS工艺制造的零件的一些重要性能。采用响应面法对表面质量和尺寸精度进行了研究，通过对实验结果的分析，建立了各因素对表面质量和尺寸精度的影响模型。在建立了满意度函数模型后，确定了最大满意度的工艺操作条件。最后，对满意度模型进行了验证。
Selective inhibition of sintering (SIS) is a new rapid prototyping method that builds parts in a layer‐by‐layer fabrication basis. SIS works by joining powder particles through sintering in the part's body, and by sintering inhibition of some selected powder areas. In this research, statistical tools were applied to improve some important properties of the parts fabricated by the SIS process. An investigation of surface quality and dimensional accuracy was conducted using response surface methodology and through analysis of the experimental results, the impact of the factors on them was modeled. After developing a desirability function model, process operating conditions for maximum desirability are identified. Finally, the desirability model is validated.
