| 中文摘要 |
| 光固化技术因其在3D打印行业中具有打印精度高且技术成熟的优势，在工业应用和学术研究方面都受到国内外的广泛关注.随着光固化3D打印技术蓬勃发展，相应而来的废弃物（光固化3D打印废塑料）作为一种新型有机固废，其增长速度不可估量，对环境带来的影响难以预计.基于现有研究，对光固化3D打印废塑料来源、处置技术和环境影响的最新研究进展进行总结分析.结果表明，光固化3D打印废塑料为共价交联热固性塑料，具有较高的活化能，内部化学结构存在对光敏感的显色基团，其原料、形成过程和目前的处置方法均可能对环境或生物体等带来潜在危害.基于此，针对光固化3D打印废塑料未来处置方式的可能性，提出展望和建议，可为光固化3D打印产业清洁发展提供助力. |
| 英文摘要 |
| In the 3D printing industry, photopolymerization-based 3D printing is considered to have the characteristics of high printing accuracy and mature technology. Therefore, it is of wide concern in industrial application and academic research. With the rapid development of photopolymerization-based technology, photopolymerization-based plastic waste will inevitably be produced in the process of product manufacturing and use. This kind of plastic waste is a new type of organic solid waste with an incalculable growth rate, and its impact on the environment is difficult to predict. Based on available research results, the latest research progress of sources, disposal technologies, and environmental impact of photopolymerization-based plastic waste were summarized and analyzed. The results revealed that the photopolymerization-based plastic waste was covalently crosslinked with thermosetting plastic. It had relatively higher activation energy and photo-sensitive chromogenic groups. There were some potential hazards to the environment and biosome caused by the raw material, printing process, and waste disposal process of photopolymerization-based plastic. Therefore, prospects and suggestions were proposed for the possibility of future disposal of photopolymerization-based plastic waste, in order to provide a reference for developing the photopolymerization-based 3D printing industry. |
