Abstract

The invention discloses light-cured 3D (three-dimensional) printing photosensitive resin which is prepared from, by weight, 2-10 parts of functional monomer, 5-10 parts of photo-initiators, 40-50 parts of low polymer, 20-50 parts of activated diluents and 1-30 parts of additives. The invention further discloses a preparation method and an application of the light-cured 3D printing photosensitive resin. The light-cured 3D printing photosensitive resin can simply realize surface functional modification of a light-cured 3D printing component. The light-cured 3D printing photosensitive resin is prepared by the aid of a light-cured 3D printing component manufacturing method based on easy modifiability of poly-pyrocatechol amine compounds. The surface of the obtained light-cured 3D printing photosensitive resin is provided with an easily modified polymer layer, various surface functional modification can be realized without destroying functionality of original materials, and a modified layer and a body are good in bondability.

Description

technical field [0001] The invention relates to a light-curing 3D printing photosensitive resin and its preparation method and application, specifically belonging to the technical field of 3D printing. Background technique [0002] At present, 3D printing technology (three-dimensional printing, also known as additive manufacturing) provides the possibility for the processing of complex shape parts. Compared with traditional manufacturing and processing methods, 3D printing has obvious advantages in the manufacture of high molding difficulty, custom materials, and customized parts and devices. Due to its high-efficiency and low-cost manufacturing methods, 3D printing, as an innovative processing technology, has been increasingly used in fields including material science, biological tissue engineering, and microfluidic research and analysis. In particular, the 3D printing technology of photo-curing method has more obvious advantages in the field of manufacturing tiny devices ...
