Problems solved by technology

[0002] At present, 3D printing technology has been widely used in many processing fields such as moulds, parts, etc., but in actual use, it is found that although there are many types of 3D printing equipment, the structural accuracy and processing efficiency of processed workpieces are high, Moreover, the energy consumption of processing operations is relatively low, which can effectively meet the needs of processing operations such as various parts and workpieces. However, currently, there are relatively few printing materials that can be effectively used in conjunction with 3D printing equipment, and the structural properties of printing materials are relatively low. Therefore, it is urgent to develop a polymer material that can effectively meet the needs of 3D printing operations in order to meet the needs of 3D printing technology. practical needs
