光固化列印(Vat Photopolymerization)之光固化溶液配方組成決定了固化材料的性質。然而，因光固化材料為高分子，對於其材料的性質有機械強度不高及熱性質不強的本質。因此，本研究以改善產品品質著稱的田口方法(Taguchi Methods)對光固化材料的性質進行探討，以寡聚合物(Oligomer)、單體(Monomer)及光起始劑(Photoinitiator)添加量與後曝光量(Exposure dosage)作為控制因子，並分析其材料得到之最大拉伸強度及玻璃轉化溫度作為品質特性，期望找出其材料機械性質與熱性質之最適化配方。
本研究使用SLA(Stereolithography)技術之光固化3D列印機與田口方法之望大特性(Larger-The-Better)機制並以寡聚合物：胺基改質聚醚丙烯酸酯(Amine modified polyether acrylate,AMPA)、脂肪酸改質聚酯丙烯酸酯(Fatty acid modified polyester hexacrylate,FAMPH)及AMPA：FAMPH重量比1：1作為控制因子A的三水準；寡聚合物與單體三丙二醇二丙烯酸酯(Tripropylene glycol diacrylate,TPGDA)之重量比例1：1、2：1及3：1作為控制因子B的三水準；光起始劑(Irgacure819：Darocur1173重量比1：1)添加量3、6及9wt%作為控制因子C的三水準；後曝光量8.8、13.2、17.6J/cm2作為控制因子D的三水準。
本研究結果顯示，在寡聚合物AMPA：FAMPH重量比1：1、寡聚合物與單體重量比例3:1、光起始劑添加量3wt%及後曝光量17.6J/cm2有機械性質最適化配方。在寡聚合物FAMPH、寡聚合物與單體重量比例1:1、光起始劑添加量6wt%及後曝光量17.6J/cm2有熱性質最適化配方。然後，各對其性質最適化配方列印出材料及分析其材料性質，並與直交表實驗組的性質比對：機械性質增益13.2%，熱性質增益8.7%。

The composition of the photo-curable resin for Vat Photopolymerization determines the properties of photo-cured material. However, due to the fact that the photo-cured material is polymer which properties have the nature of low mechanical strength and low thermal property. Therefore, ,this study adopts Taguchi method, which is known for improving product quality, to investigate the properties of photo-cured materials. By using oligomer, monomer, photoinitiator, exposure dosage as control factors, max tensile strength and glass transition temperature were obtained by analyzing the material as quality characteristics. It is hoped to find the optimal formula for the mechanical property and thermal property of photo-cured material.
This research adopts SLA(Stereolithography) photo-curing 3D printer and Taguchi method's Larger-The-Better mechanism, and uses oligomer: Amine modified polyether acrylate(AMPA), Fatty acid modified polyester hexacrylate(FAMPH) and AMPA: FAMPH weight ratio is 1:1 as the three levels of control factor A; the oligomer: monomer(Tripropylene glycol diacrylate, TPGDA) weight ratio are 1:1, 2:1, and 3:1 as the three levels of the control factor B; the addition amount of photoinitiator (Irgacure819: Darocur1173 weight ratio is 1:1) is 3,6 and 9wt% as the three levels of the control factor C; the exposure dosage amounts of 8.8, 13.2, 17.6J/cm2 as the three levels of control factor D.
The results show that an optimal formula for mechanical property was found as the oligomer weight ratio of AMPA:FAMPH is 1:1, the weight ratio of oligomer and TPGDA is 3:1, the addition amount of photoinitiator is 3wt%, and the exposure dosage amount is 17.6J/cm2,; an optimal formula for thermal property was found as the oligomer is FAMPH, the FAMPH and TPGDA weight ratio is 1:1, photoinitiator addition amount is 6wt%, and exposure dosage amount is 17.6J/cm2. Then, mechanical property gain 13.2%, thermal property gain 8.7%.each optimized formula for its properties was printed out and the material properties were analyzed and compared with the properties of the experimental group in the Orthogonal array: mechanical property gained 13.2%, thermal property gained 8.7%.
