Sources, Disposal Technologies, and Environmental Impact of Photopolymerization-based 3D Printing Plastic Waste

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.
