Abstract
The invention discloses a light-curing 3D printing photosensitive resin, which is prepared from the following components in parts by weight: 2-10 parts of functionalized monomers, 5-10 parts of photoinitiators, and 40-50 parts of oligomers , Active diluent 20-50 parts and additive 1-30 parts. It also discloses its preparation method and application. The invention provides a photosensitive resin for photocuring 3D printing, which can simply realize the surface functional modification of photocuring 3D printing parts. The light-curing 3D printing photosensitive resin of the present invention is obtained based on the easy modification of polycatechol amine compounds and the component manufacturing method of light-curing 3D printing. The surface layer of the obtained photocurable 3D printing photosensitive resin has an easy-to-modify polymer layer, which can realize various functional modifications of the surface without destroying the functionality of the original material, and has good bonding between the modified layer and the body.
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 ...
