Natural superwettable surfaces have received extensive attention due to their unique wetting performance and functionalities. Inspired by nature, artificial surfaces with superwettability, particularly superamphiphobicity, i.e., superhydrophobicity and superoleophobicity, have been widely developed using various methods and techniques, where 3D printing, which is also called additive manufacturing, is an emerging technique. 3D printing is efficient for rapid and precise prototyping with the advantage of fabricating various architectures and structures with extreme complexity. Therefore, it is promising for building bioinspired superamphiphobic surfaces with structural complexity in a facile manner. Herein, the state-of-the-art 3D printing techniques and methods for fabricating superwettable surfaces with micro/nanostructures are reviewed, followed by an overview of their extensive applications, which are believed to be promising in engineered wettability, bionic science, liquid transport, microfluidics, drag reduction, anti-fouling, oil/water separation, etc.
天然超润湿性表面因其独特的润湿性能和功能而受到广泛关注。受自然启发，具有超润湿性，特别是超两疏性（即超疏水性和超疏油性）的人工表面已通过各种方法和技术得到广泛开发，其中3D打印（也称为增材制造）是一种新兴技术。3D打印对于快速精确的原型制作非常高效，具有制造极其复杂的各种结构和构造的优势。因此，它有望以简便的方式构建具有结构复杂性的仿生超两疏表面。在此，综述了用于制造具有微/纳米结构的超润湿性表面的最新3D打印技术和方法，随后概述了它们的广泛应用，这些应用在工程润湿性、仿生科学、液体传输、微流体、减阻、防污、油/水分离等方面被认为具有广阔前景。
