Abstract

The invention discloses a low-cost environment-friendly photosensitive resin composition. The photosensitive resin composition comprises 100 parts of unsaturated polyester resin, 0-500 parts of acrylic resin, 0-500 parts of aerobic acrylic ester resin, 0-500 parts of polyethylene glycol dimethyl acrylic resin, 5-500 parts of diluent, 0-10 parts of defoamer, 0-10 parts of flatting agent, 0-5 parts of antioxidant and 0.1-10 parts of photoinitiator. The photosensitive resin composition is low in cost and wide in applicability and used for 3D printing technique, effectively solves the problems of 'sticky plate' and low curing speed and the like due to high bonding strength of unsaturated polyester resin and lays the foundation for massive application of the 3D printing technique.

Description

technical field [0001] The application relates to a photosensitive resin composition and its application in three-dimensional printing, belonging to the technical field of chemical industry. Background technique [0002] Three-dimensional (3Dimension, abbreviated as 3D) printing technology is a general term for a series of rapid prototyping technologies that are directly driven by digital models to quickly manufacture three-dimensional physical entities of arbitrary complex shapes. , which is different from the traditional "subtractive" manufacturing mode, is a green and intelligent "additive" manufacturing. [0003] Light-curing 3D printing technology has the advantages of fast molding speed, high printing accuracy, and good surface quality. Its essence is an additive advanced manufacturing technology. Orderly stacking to make the desired molding. At present, stereolithography 3D printing mainly includes laser stereolithography appearance (SLA) 3D printing and digital lig...
