| Abstract | The resolution in microstereolithography(μSL) is highly dependent on the photopolymerization process. Using finite volume method to simulate a photon induced polymerization in HDDA with Gaussian illumination on the surface, a numerical model is developed to consider the influence of diffusion dominant effect under high intensity. Simulations were performed to investigate the growth of conversion profile as a consequence of competition between photochemical reaction and mass diffusion. Numerical result reveals some interesting phenomena under illumination of high intensity. A solution of pulsed laser curing is proposed in order to improve the resolution in μSL process. |
