    Abstract: 在DLP-SLA快速成型系統中,工件成型的品質會受製程參數、機台性能及材料影響,若能找到改善方法,便能提高快速成型機性能及更精準的模型。本研究首先對快速成型機進行製程參數最佳化,目的為選擇適當的加工參數使工件尺寸具有最小標準差及減少製程時間,利用部分因子實驗篩選出影響顯著之因子,再由反應曲面法之中央合成設計實驗,求得最佳製程參數。其次DLP-SLA快速成型系統常見光源為紫外光或可?光,兩者均有能量分布不均之現象,光源不均勻會導致工件標準差上升,此現象可由灰階補償方法產生光罩,便能改善能量分布不均的情形。最後在最小標準差的形況下,分別對X方向與Y方向進行收縮係數補償,即可獲得更加準確的工件。
    In digital light processor stereolithographic (DLP-SLA) system, the quality of part is affected by the processing parameter, the performance of the machine and the material. If we improve the factor above, the performance of the rapid prototyping machine will be promoted, and the more accurate part will be made.In this thesis, first, we optimize the process parameter of rapid prototyping machine for the appropriate machining parameters to minimize standard deviation in size and the process time of the part. Secondly, the light source of DLP-SLA usually is the ultraviolet light or visible light, both of which are the uneven distribution of energy that contributes the high standard deviation of the part. We use the gray-scale light mask to compensate the insufficient of the original mask to get the minimum standard deviation of the size. Finally, we compensate the shrinkage factor, respectively, in the X direction and Y direction to get more accurate 3D print part.
