Physics and Technology of Printing: Effects and Mechanisms

This lecture explores the physics and technology behind printing processes, focusing on the effects and mechanisms that influence the final printed patterns. Topics include the coffee ring effect, convective and Marangoni flows, line formation dynamics, pattern generation, substrate impact, instabilities, and the role of drop spacing in bulging and stability. The instructor delves into the importance of substrate choice, drag-out tails, inks for large-scale manufacturing, curing techniques, and substrate modifications to optimize printing outcomes.
