Direct sound printing (DSP) is a recent development in additive manufacturing processes using sound waves, in which cavitation bubbles created by a focused ultrasound field polymerize the liquid resin via the sonochemistry route. This article presents the first attempt to create functional parts, such as cantilevers and millifluidic systems in polydimethylsiloxane using DSP. The numerical simulations of acoustic propagation in the DSP and possible high-pressure zones in different media during the process are presented. The printed parts were characterized, and porosity analyses of the printed parts and postprocessing of the ultrasound source motion were performed.
直接声印（DSP）是增材制造工艺中利用声波的一项最新进展，在该工艺中，聚焦超声场产生的空化气泡通过声化学途径使液态树脂聚合。本文首次尝试使用DSP制造聚二甲基硅氧烷中的功能部件，如悬臂和微流体系统。文中给出了DSP中声传播以及该过程中不同介质中可能的高压区域的数值模拟。对打印部件进行了表征，并对打印部件进行了孔隙率分析以及对超声源运动进行了后处理。
