Abstract
This paper presents a parametric study of a dip-drawing process for making high aspect-ratio polymeric microneedles. The process involves dip-pad spin coating, mold based dip-drawing, UV-curing, necking-break, and final curing. To gain more insight into the process, we characterize the dip-drawing speed and curing time to determine the critical parameters for the microneedle geometry control. The experiment results show that the diameters of the microneedle tips are gradually decreased to 1.69 $\mu$m with increasing of drawing speed.
