Fluid mechanics of slot-coating in photopolymer-based AbstractThis paper describes the fluid mechanics of the slot-coating process in the context of rapid layered manufacturing. It has been conjectured that slot-coating would successfully address a number of common difficulties encountered in the formation of thin layers from a highly viscous fibre—photopolymer composite liquid. The objective of the present study was therefore the development Frequency response of slot coating flow to gap This type of disturbance is usually called the gap oscillation, and caused by the substrate thickness variations, mechanical vibration of the coating die or roll, and roll run outs. Here, we analyze the effect of fluid properties, operating conditions and die configurations on response of slot coating …
