| Research Abstract |
In this study, we develop a rapid prototyping technique of a complex three-dimensional shape in a microchannel that in mind for use in the model experiment for the behavior elucidation of the red blood cells. We have proposed a three-dimensional lithography using DMD (digital mirror device) in combination with high-speed confocal scanner. The optical design to eliminate the illumination non-uniformity is particularly concerned by introducing a beam homogenizer and spatial filter, and it reduces to 10% the difference in brightness over the entire region. Since the curing spot of confocal effect is tend to be thicker than the theoretical confocal depths, the possibility of thinner polymerization is indicated by decreasing the intensity of the laser and a longer exposure time.
