Research of Matching Character of Light Source in Integral Stereolithography System with Photo-Curable Resin

Abstract:

In order to choose right photo-curable resin for integral stereolithography (SL) system, researches have been carried out to find the matching of light source of integral SL System and the photo-curable resin. Spectrum distribution of light source is investigated with raster spectrum meter. The research result shows that main light power of the light source distributes in the span of 400-650nm, and there is few light power distributing in other span. Absorption spectrum of several photo-curable resin is measured with grating spectrometer, and measure results indicates that sample 1 (ad2230) has good absorption in the span of 0-650nm, and the average absorption ratio is above 80%. Other resins (ad2210, jd01, jd02) have only good UV absorption, the average absorption ratio is almost 100% particularly under 300nm, and the absorption band is under 350nm. As a result, ad2230 is the right photo-curable resin for integral SL system, and three-dimensional parts are fabricated by the integral SL System with the resin (ad2230). The research results lay a foundation for building objects with photo-curable resin by using integral SL System.
