Investigation of Solidification Characteristics of Resin for Integral Stereolithography System
Photo-curable resin’s solidification under beam exposure in integral stereolithography (SL) is a dynamic process. Firstly, the up-part in photo-curable resin solidifies after absorbing enough energy; and then with the beam exposure, after the beam penetrates the solidified resin, the liquid resin un...

Summary: | Photo-curable resin’s solidification under beam exposure in integral stereolithography (SL) is a dynamic process. Firstly, the up-part in photo-curable resin solidifies after absorbing enough energy; and then with the beam exposure, after the beam penetrates the solidified resin, the liquid resin under solidified resin have the opportunity to be cured. But the model which describes the solidification characteristics for photo-curable resin in SL process does not reflect the dynamic characteristics, and obvious predicting error will be introduced. In this paper, a solidification characteristics model of the photo-curable resin UV-2230, which describes the resin’s dynamic characteristics in solidifying process, is established with least square method in experiments. By using the model, critical exposure of the resin, penetration depth of the liquid resin and penetration depth of the solid resin are obtained. The research provides a base for improving the building accuracy for integral SL system. |
