現今光固化成型技術發展出以DLP投影光照射樹酯成型,軟體需將模型切層後產生光罩,並配合機台作光罩修正。 本文將切層輪廓依照塗色演算法轉換為光罩型式,可輸出至DLP之3D列印機,並探討產生之光罩加工過程與結果。 本文於實驗中,將光罩輸出至機台實驗,實驗12組模型經由量測與計算結果可得知實體模型未補償前X軸放大+0.665%,Y軸縮小-3.446%,經由補償後並實驗量測可得X軸放大修正為+0.273%,Y軸縮小修正為-0.266%,X軸修正幅度為0.392%,Y軸修正幅度為3.18%。 補償後實際量測得知結果與未補償前實際量測,方塊補償前與原始模型誤差X軸為0.0998mm,Y軸為0.507mm,補償後與原始模型誤差X軸為0.041mm,Y軸為0.04mm,補償前後實際修正誤差幅度X軸為0.0588mm,Y軸為0.467mm。
Today light curing technology developed with DLP projection light irradiation resin molding, the software required to generate the mask layer after model sliced, and with the machine as a mask correction. This paper will outline slicing layers according to coloring algorithms convert the mask pattern can be output to the DLP's 3D printing machine, mask and explore the process and result. This paper in the experiment, the mask is output to the machine experiment 12 groups via measurements and model calculations can be learned before the model uncompensated X axis zoom + 0.665%, Y-axis shrink -3.446%, and compensated by experimental measurements available X-axis zoom revised to + 0.273%, Y-axis shrink revised to -0.266%, X-axis correction margin of 0.392%, Y-axis correction margin of 3.18% The actual measurement compensated and uncompensated result that prior to the actual measurement, and before the original model error compensation box X axis 0.0998mm, Y axis 0.507mm, after compensating for the original model with the X-axis error 0.041mm, Y axis 0.04mm, compensation before and after the actual margin of error correction X axis is 0.0588mm, Y axis 0.467mm
