介绍了使用增材制造作为通过立体光刻从单一建筑材料构造异质衬底的方法的概念。在散装材料内的空气腔的动态变化被用来控制主介质的有效介电常数。数字驱动层工艺能够实现局部介电常数的全三维变化。立体光刻的高分辨率使空气夹杂特征的亚毫米控制成为可能。与不同的空气分数的有效介电常数的测量值进行了比较，分析结果。
The concept of using additive manufacturing as a method to construct heterogeneous substrates from a single building material via stereolithography is introduced. The dynamic variation of air cavities within the bulk material is used to control the effective permittivity of the host medium. The digitally driven layer process enables full three-dimensional variation of the local permittivity. The high resolution of stereolithography enables sub-millimetre control of air inclusion features. Measurements of the effective permittivity with different air fractions have been compared to analytical results.
