Abstract

The invention discloses a preparation method and application of photosensitive resin for ultrasonic curing 3D printing. The photosensitive resin mainly comprises the following raw material components in percentage by mass: active components: 70-90 percent (in percentage by total mass of the active components, and the same below) of a mixture of a low polymer A, a low polymer B and an acrylic ester monomer according to the ratio of 50: 15: 35 and 10-30 percent of an active diluent, and auxiliaries: 1-10 percent of a cationic initiator, 1-6 percent of a free radical photoinitiator, 1-8 percent of a promoter, 0.1-1.5 percent of a flatting agent and 0.1-1.5 percent of a defoaming agent. The raw material components are mixed according to the mass percentage, and then heated and stirred into transparent light-yellow liquid to prepare the photosensitive resin. After ultrasonic curing 3D printing molding, the volume shrinkage of a product is smaller than or equal to 1.0 percent, the warpage factor CF (6) is equal to + / - 0.2 percent, and the warpage factor CF (11) is equal to + / - 0.8 percent. The molded product is high in precision and can be applied to manufacturing of key parts for aviation.

Description

technical field [0001] The technology relates to a preparation method and application of a photosensitive resin for ultraviolet curing 3D printing. Background technique [0002] Photocuring 3D printing (Three Dimensional Printing, 3DP), which is a kind of rapid prototyping technology. As a new generation of 3D printing, it uses liquid photosensitive resin to form parts and cures with ultraviolet light. [0003] a technique. It has the advantages of simple operation, fast forming speed, no pollution in the forming process, and high precision of formed parts. [0004] Use in the office environment and other advantages. Therefore, the application prospect is very promising. [0005] Photocuring 3D printing uses all polymer photosensitive resins. A class of polymer photosensitive resin is [0006] Acrylate-based photosensitive resin, which belongs to free radical photosensitive resin, has the advantages of fast curing speed and low price. [0007] However, the curing shri...
