气溶胶喷射打印（AJP）是一种有前途的微尺度增材制造技术，适用于印刷和柔性电子产品的新兴应用。然而，这一新兴技术的更广泛采用受到对该过程的有限基本理解的阻碍。这项工作的重点是一个关键的和低估的方面的过程中，鞘气和冲击引起的干燥之间的相互作用。结合重点实验的支持，从数值模拟，它表明，这些影响有一个显着的影响的过程中，包括沉积速率，分辨率和形态的关键输出。这些效应可以放大油墨成分或雾化产率的微小变化，从而增加工艺灵敏度和漂移。此外，这些影响可以混淆在线过程监测和控制的基础上经验的可观测的策略。提出了直接操纵这种环形干燥现象的策略，为定制和研究该过程提供了一个可行的工具。这项工作阐明了打印机设计，油墨配方和打印参数的耦合效应，建立了一个更强大的理论框架，以了解AJP过程，并推进这一有前途的技术的成熟度。
Aerosol jet printing (AJP) is a promising microscale additive manufacturing technology for emerging applications in printed and flexible electronics. However, the more widespread adoption of this emerging technique is hindered by a limited fundamental understanding of the process. This work focuses on a critical and underappreciated aspect of the process, the interaction between drying induced by the sheath gas and impaction. Combining focused experiments with support from numerical modeling, it is shown that these effects have a dramatic impact on key outputs of the process, including deposition rate, resolution, and morphology. These effects can amplify minor changes in ink composition or atomization yield, increasing process sensitivity and drift. Moreover, these effects can confound strategies for in-line process monitoring and control based on empirical observables. Strategies to directly manipulate this annular drying phenomenon are presented, providing a viable tool to tailor and study the process. This work clarifies coupled effects of printer design, ink formulation, and print parameters, establishing a more robust theoretical framework for understanding the AJP process and advancing the maturity of this promising technology.
