中文摘要：
采用蒙特卡罗方法分析了光子在树脂中的输运过程，建立了紫外光单点固化模型，并进行了单点固化过程的模拟计算，通过曝光固化实验验证了该算法的可靠性．理论模拟和实验结果表明，当曝光能量达到临界值，固化点的高度和直径随曝光时间、功率的增大呈对数关系增大．利用该算法可以模拟各种不同光强分布的曝光固化过程，为加工分辨率的提高和工艺参量的优化提供理论基础．
英文摘要：
The transition process of photons in the resin is studied based on method of Monte Carlo （MC）. The model of UV-solidifying point is constructed, the simulated calculation of single-point solidifying process is carried out,and the reliability of the model is confirmed by the curing exposure experiments. The results of simulated calculations and solidifying experiments indicate that, when the exposure intensity exceed the critical value,the depth and diameter of solidifying point logarithmically increase following with the increasing exposure time and power. The different solidifying processes with various conditions of laser intensity distribution can be simulated by the model, to the benefit of effective prototyping precision and optimized technical parameters.
