The development of Nano/Micro manufacturing technologies is growing rapidly and in the same manner, the
investments in these areas are increasing. The applications of Nano/Micro technologies are spreading out to
semiconductor production technology, biotechnology, environmental engineering, chemical engineering and aerospace.
Especially, SLA is one of the most popular applications which is to manufacture 3D shaped microstructure by using UV
laser and photo sensitive polymer. To make a high accuracy and precision shape of microstructures that are required from
the diverse industrial fields, the information of interaction relationship between the photo resin and the light source is
necessary for further research.
Experiment of solidifying photo sensitive polymer by using UV LED is the topic of this paper and the purpose of this
study is to find out what relationships do the reaction of the resin have in various wavelength, power of the light and time.
