Abstract: This research focuses on fabricating bioinspired microstructures using single-layer photopolymerization (SLP), a process that uses UV light to solidify resins like LV and Spot E. This research takes inspiration from cacti which have the ability to harvest water in the driest environments. The goal is to fabricate small microstructures as spikes that can be manipulated by UV light patterns for accurate hydro testing. By understanding these interactions, groundbreaking innovations in self-cleaning surfaces, fog harvesting, and biomedical coatings can be made possible. Furthermore, by changing the cacti's geometry, orientation, and pitch of microstructures to spot the spikes' effects on water adhesion, droplet movement, and flow behavior. Additionally, adjusting fabrication parameters such as UV exposure time, and resin composition, we aim to optimize the structural integrity and hydrodynamic performance of these materials. The ability to modify these properties provides valuable understanding of designing multi-purpose surfaces. The results of this study will help advance additive manufacturing, and functional surface engineering. By understanding how nature-inspired designs influence water interaction, we can create more biomimic materials effectively. This research has the potential to improve real world applications from water-harvesting technologies, medical coatings, and future developments in sustainable materials. Finally, by improving the SLP process, the research will illustrate how nature-inspired designs can pave the way for innovation and practical solutions for multiple industries.
