摘要：针对现有的喷墨打印技术需根据喷印材料的特性定制而较难直接用于不同材料打印的问题，设计了一
种基于菲涅尔透镜聚焦的声泳打印装置。该装置由超声发生器、超声换能器、菲涅尔透镜以及供液系统组成。
首先，利用多物理场耦合仿真软件模拟液滴在声辐射力作用下的滴落过程，并分析了喷嘴到基底距离、菲涅尔
透镜厚度及基底不同边界等因素对声场压力分布的影响，以及声场压力、喷嘴直径及材料黏度对液滴喷射过
程的影响。其次，采用构建的声泳打印装置进行喷射成滴实验，通过调整超声发生器输出功率实现了不同黏度
的聚乙二醇溶液的喷射以及 UV 胶的喷射。实验结果表明：该微滴喷射系统能产生一致性较好的微滴，喷印出
的微透镜尺寸波动范围在 2% 以内，证明了该装置的稳定性以及实现了不同材料微滴喷射的可行性。

Abstract: An acoustophoretic printing device based on Fresnel lens has been designed to address the existing
problem that inkjet printing technology needs to be customized according to the properties of the material.
The device consists of an ultrasonic generator, an ultrasonic transducer, a Fresnel lens and a liquid supply
system. Firstly, multi-physics field coupling simulation software is used to simulate the drop process of droplets
under the action of acoustic radiation force, and the influence of factors such as the distance from the nozzle to
the substrate, the thickness of the Fresnel lens and the different boundaries of the substrate on the sound field
pressure distribution, as well as the sound field pressure, nozzle and other factors are analyzed. Influence of
diameter and material viscosity on droplet ejection process. Secondly, the constructed acoustophoresis printing
device was used to carry out the spray droplet experiment. By adjusting the output power of the ultrasonic
