Description

technical field [0001] The invention belongs to the field of polymer materials and relates to an improved 3D printing photosensitive adhesive resin and a preparation method thereof. Background technique [0002] High-speed light-curing molding technology has been widely used in the world in recent years, especially 3D printing technology, which is a so-called additive molding technology that mainly manufactures three-dimensional products by adding materials layer by layer. It has low energy consumption, low cost, With the characteristics of high forming precision, it can print any complex parts that cannot be processed by traditional processing methods. There are still some problems in the development of the 3D printing photosensitive adhesive provided at present: the current 3D printing adhesive is mainly made of thermoplastic materials, such as PLA and ABS and other polymer materials, which need to be heated during the molding process, resulting in inconvenient use. In ad...
