在激光引导下将材料组装成微结构正引起人们的广泛关注。与标准的自上而下方法相比，激光打印能够以微米/亚微米的分辨率对各种材料进行图案化，形成2D和3D结构，并且能量和材料浪费更少，因此激光打印在医疗器械、传感器和微电子等领域具有广阔的应用前景。液体组装提供了比粉末更小的特征尺寸，并且在相对简单的设置、容易处理和回收方面比其他状态的物质具有优势。然而，简单的设置隐藏了各种潜在的机制，这些机制不能简单地根据开始或结果材料来识别。本进度报告根据材料的来源--预制的或本地合成的--调查了各种机制。在每个类别中，方法都是根据物质沉积的驱动力来定义的。对每种方法的优点和局限性进行了批判性的讨论，并对各种方法进行了比较，揭示了推进这一领域所需的未来方向和发展。
Assembly of materials into microstructures under laser guidance is attracting wide attention. The ability to pattern various materials and form 2D and 3D structures with micron/sub-micron resolution and less energy and material waste compared with standard top-down methods make laser-based printing promising for many applications, for example medical devices, sensors, and microelectronics. Assembly from liquids provides a smaller feature size than powders and has advantages over other states of matter in terms of relatively simple setup, easy handling, and recycling. However, the simplicity of the setup conceals a variety of underlying mechanisms, which cannot be identified simply according to the starting or resulting materials. This progress report surveys the various mechanisms according to the source of the material-preformed or locally synthesized. Within each category, methods are defined according to the driving force of material deposition. The advantages and limitations of each method are critically discussed, and the methods are compared, shedding light on future directions and developments required to advance this field.
