Abstract

The invention discloses light-cured resin for a 3D printer and a preparation method for the light-cured resin. The light-cured resin is prepared from the following ingredients in parts by weight: 85-95 parts of dilution monomer, 5-10 parts of cross-linker, 0.1-1 part of leveling agent, 3-5 parts of oligomer and 3-10 parts of photoinitiator. According to the light-cured resin disclosed by the invention, the reduction ratio of a cured formed object is reduced while the accuracy of a printed object is improved, so that the working efficiency is increased. Another object of the invention is to provide the preparation method for the light-cured resin for the 3D printer.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a photocurable resin used in a 3D printer and a preparation method thereof. Background technique [0002] 3D printing technology, also known as three-dimensional printing technology, refers to a 3D printer that can "print" a real object, and uses layered processing and superposition forming to increase materials layer by layer to generate 3D entities. The most prominent advantage of 3D printing technology is that it can directly generate objects of any shape from computer graphics data without machining or molds, thereby greatly shortening the product development cycle, improving productivity and reducing production costs. [0003] The core of the development of 3D printing technology is not printing, but the constraints of material technology. Only with the development of new material technology can 3D printing technology be further practical. At present, 3D prin...
