Amphiphobic surfaces are obtained by lowering the surface energy through changes in surface geometry. These changes can be designed on the surface, thereby altering its wettability, and in turn rendering it amphiphobic. The main geometrical entities behind this phenomenon are reentrant geometries which prevent the solid-liquid interface tension from breaking, thereby resulting in contact angles greater than 90°. The science behind modelling and manufacturing of these reentrant geometries is well established apart from manufacturing them via extrusion-based 3-Dimensional printing processes. This review paper in identifying this gap summarizes various characterization parameters for surface wettability followed by identifying the role of surface reentrant geometries to introduce superamphiphobicity in polymers. The focus of the paper then moves towards achieving amphiphobicity using 3D printing processes where the current state of research is discussed in terms of reentrant profiles and achievement of high static contact angles. Role of the most common yet rarely reported Fused Deposition Modelling technique is discussed in more detail and a preliminary investigation based on characteristics flow and printing parameters used in Fused Deposition Modelling has been presented. The surface amphiphobicity is achieved in a one-step process characterized by high static contact angles with low and high surface tension liquids owing to air entrapment in characteristic layer-by-layer deposition features obtained in Fused Deposition Modelling.

两性表面是通过改变表面几何形状来降低表面能而获得的。可以在表面设计这些变化，从而改变其润湿性，从而使其具有两亲性。这种现象背后的主要几何形状是凹入几何形状，可防止固液界面张力破裂，从而导致接触角大于90°。除了通过基于挤压的3维印刷工艺来制造折返几何图形之外，这些折返几何图形的建模和制造背后的科学也得到了很好的确立。这篇关于确定该间隙的综述论文总结了表面润湿性的各种表征参数，然后确定了表面凹角几何形状在聚合物中引入超疏水性的​​作用。然后，本文的重点转向使用3D打印过程实现两亲性，其中根据折返轮廓和高静态接触角的实现来讨论当前的研究状态。对最常用但很少报道的熔融沉积建模技术的作用进行了更详细的讨论，并提出了基于特征流和熔融沉积建模中使用的印刷参数的初步研究。表面两亲性是通过一步法实现的，该过程的特征在于由于熔融沉积建模中获得的特征性逐层沉积特征中的空气截留，与低和高表面张力的液体具有较高的静态接触角。
