不同3D彩色列印技術印刷物理品質特性之研究

A Study on Print Physical Quality Attributes of Different 3D Color Printing Technologies

3D列印的問世已經超過30年，隨著3D列印技術的功能性提升，其在工業製造應用也越來越多元化，對於不同被印材料的色彩呈現與固化再現的研究資料,迄今仍相當有限。而3D彩色列印可以讓模型更真實地表現3D效果，但是關於其表面印刷物理品質的評估研究，都缺乏對被印材料的全面性且客觀性驗證，在本研究中以環保、生動的石膏粉體及光固化樹脂材料之3D彩色列印技術為例，設計並列印一套印刷物理品質測試導表，通過量測3D彩色列印模型表面的解析度、光澤度、耐摩擦度和耐候度之特性，並通過獲取被印材料量測表面的印刷物理品質特性，探討不同3D彩色被印材料著色層與其固化劑之間的相關性進行研究分析。經本研究分析歸納以下結論：（一）不同3D彩色列印被印材料的色彩模型，經塗布固化劑後表面的印刷物理品質特性（解析度、光澤度、耐摩擦度、耐候度）等均有差異的影響。（二）3D彩色列印解析度於印前設計以0.5mm以上的設定，對3D彩色列印模型的影像品質有最佳呈現效果。（三）3D彩色列印色彩模型經塗布固化劑後，對於光澤度增加、耐摩擦度增加、耐候度的變化有顯著差異的影響。

The advent of 3D printing is over 30 years. With increasing functionality of 3D printing technology, 3D printing is getting diversified in industrial manufacturing applications. So far, the research about color rendering and curing reproduction for different printed materials has still been limited. 3D color printing does help a 3D model effect look realistic. However, in existing research, there is a lack of comprehensive and objective verification of printed materials about its physical quality evaluations of printed surface. In this 3D color printing technology study, take the materials of ecofriendly and vivid gypsum powder and UV-curing resins as examples, design and print a set of test guides of printing physical quality; measure the physical quality attributes of the 3D color printing models, including resolution, gloss, abrasion resistance and weather resistance. According to these physical quality attributes from measured surface of printed materials, this research analyses and explores the correlation between their colored layers and curing agents of the different 3D color printed materials. After analysis, the conclusions of this study are as followings: (1) The printing physical quality attributes (resolution, gloss, abrasion resistance and weather resistance, etc.) of different 3D color printing materials’surface are significant impact after curing agent is coated and cured. (2) In pre-print design of 3D color printing, when a resolution is set 0.5mm or above, the image quality of the 3D color printing model will get the best performance. (3) A 3D color printing model gets a significant effect on value of gloss, abrasion resistance and weather resistance after it is being curing agent coated and cured.
