When a small tube is dipped into a liquid surface, surface tension forces cause the liquid in the tube to rise vertically against the gravity. When the tube is flexible, hydrostatic pressure difference caused by the capillary flow deforms the tube and the deformation which narrows the flow route changes the rising velocity. We study a simple model of this elastocapillary interaction in the context of the surface-tension-driven vertical rise of a liquid between two long flexible hydrophilic sheets that are held a small distance apart at one end. We provide an analytical theory for the rise rate of the liquid and show that our experiments are consistent with the theory.

The mechanical stability of 3D-printed structures is critical for their performance across various applications, where geometric design plays a pivotal role in determining their resilience. Understanding the factors that contribute to the collapse of these structures is essential for optimizing their design. In this study, we fabricated vertical repetitive pattern structures using a Formlabs 3D printer, followed by post-processing with isopropyl alcohol (IPA). The collapse behavior of the printed patterns was visualized, revealing that the extent of collapse varied depending on geometric modifications. These findings provide key insights into the structural collapse mechanisms of 3D-printed architectures, informing future design strategies aimed at improving mechanical durability and preventing collapse. This version introduces the topic with general context before transitioning to your specific experimental approach.
