Abstract

The controlled formation of curved, three-dimensional (3-D) microstructures can be accomplished through solidification from a liquid phase. As a demonstration, we have placed objects in contact with the interface of a photopolymerizable liquid and air to create various liquid menisci that were subsequently solidified with ultraviolet radiation. Geometric control is achieved through variation of physical and environmental parameters; for example, solidified menisci formed at 25 °C were 300 μm taller than those formed at 7 °C. Comparisons between the polymerized structures and theoretical predictions for liquid menisci indicate that the polymerization process results in repeatable changes in contact angle and meniscus size.
