材料噴塗成型技術(Material Jetting, MJ)是精準度較高的3D列印製程之一，而製程中支撐材的使用是必須的。但列印成品去除支撐材後，其表面粗糙度及尺寸精度不佳。故本研究針對機台各模組進行設計及優化、由製程參數測試中找出最適化參數並且提出能提升列印品質之策略進行研究，藉由以上的改善方法使得成品品質提升。

本研究使用自組光固化3D列印機，並針對機構各模組進行設計及優化提升機台的穩定性以及列印品質。同時從液滴基本性質、疊層厚度、滾輪最佳轉速以及材料的墨量選擇等測試中找出各項最適合之參數。接著本研究使用最適合之參數並配合本研究所提出之列印策略進行測試，從中發現此改善後的製程與原先相比，成品的表面粗糙度大幅降低了63%，而在XY水平方向的尺寸精度也從原先的誤差4.8%降到0.3%。由此可證明本研究所做的製程改善以及提出之列印策略皆能使成品在去除支撐材後的表面品質提升。

Material Jetting (MJ) is one of the more accurate 3D printing processes, and the use of support material in the process is necessary. However, after the finished product is printed and the support material is removed, the surface roughness and dimensional accuracy are poor. Therefore, this study designed and improved each module of the machine, found the most suitable parameters from the process parameter tests and proposed a strategy to improve the printing quality. The above improved methods improved the quality of the finished product.

This study used a self-created light-curing 3D printer. Also, designing for each modules of the machine to improve the stability and the printing quality. At the same time, the most suitable parameters are found out from the tests of the basic properties of the droplets, the thickness of the laminate, the most suitable rotational speed of the roller, and the selection of the amount of material. Then, it used the most suitable parameters and the printing strategy proposed by this study together to do tests. It was found that the improved process was significantly reduced by 63% compared to the original process, and the dimensional accuracy in the XY horizontal direction was reduced from the original error of 4.8% to 0.3%. It proves that the process improvement and the proposed printing strategy of this research can improve the surface quality of the finished product after removing the support material.
