3D列印可透光材質厚度對於亮度影響之分析
The Effect of Thickness Induced Light Intensity by 3D Printed Translucent Materials
摘要
近年來，由於 3D 列印的普及化，有關於 3D 列印的相關研究變得 越來越熱門。然而，3D 列印仍然存在著許多待解的問題，其中之一便是列印成品的顏色。在現有的技術中，想要讓一個 3D 列印成品中包含多種顏色需要付出高於單種顏色許多倍的代價。在我們這項研究中，我們嘗試使用單一種顏色的 3D 可透光列印材料，並藉由控制列印成品的厚度以及使用光源來照射列印成品來達成類似灰階的效果。我們使用比爾 -朗伯定律 (Beer-Lambert Law) 來找出透射光亮度與 3D 可透光列印材質厚度的關係，接著再藉由韋伯定律 (Webber’s Law) 配合使用者研究 (User Study)，從有限的 3D 列印厚度中區分出明顯的對比層次。在這樣的方法之下，我們不需要付出昂貴的代價也可以使 3D 列印成品出現不同於以往的效果。

Research works relate to 3D printing have been activated recently because of the widespread of 3D printing in the past few years. However, there are still many unsolved issues in 3D printing. One of them is the coloring of 3D-printed objects. Compare with single color 3D-printed objects, we have to pay much higher cost to make them colorful, even with today's technology. In our work, a method is proposed to make 3D-printed objects have the grayscale appearance while irradiated with a light source by controlling the thickness of 3D translucent materials. We firstly use Beer-Lambert law to evaluate the relationship between the thickness of 3D translucent material and the intensity of transmitted light. Thereafter, we use Webber’s law and conduct user studies to produce clear level of grayscale on a 3D printed object with limited 3D translucent material thickness. This study shows that one can generate new and different effects on 3D-printed objects even if a low-cost 3D printed is needed.
