RP技术所使用的材料也已从开始的光敏固化树脂领域扩展到其它诸如塑料、金属、陶瓷等领域，工艺也不断得到改进。

RP technology is also used material from the beginning of the photosensitive resin extended to other areas, such as plastic, metal, ceramics and other fields, technology has also been improved.

借助金属层，其光学密度已达到5.5。由于这种有机材料是负性光敏抗蚀剂，所以加工过程相当简单。

Its optical density, with help from a metallic layer, has been achieved at 5.5. Since this organic material is a negative photoresist, the fabrication process is rather simple.

为了降低DSSC的成本，最近几年研究者们开始关注使用非金属有机光敏剂染料来代替贵金属配合物。

To reduce the cost of DSSC. researchers have begun to pay close attention to the use of non-metallic organic photosensitizer dye as replacement of precious metal complexes in recent years.
