Abstract

The invention discloses a composition based on bismaleimide / acrylic acid liquid crystal photosensitive resin and application of the composition in 405nm 3D printing. The composition capable of being used for 405nm 3D printing is prepared by mixing the following components in parts by weight: 10 to 50 parts of bismaleimide-based photosensitive resin, 10 to 50 parts of acrylic liquid crystal photosensitive resin, 10 to 50 parts of acrylic resin, 0 to 25 parts of polyethylene glycol dimethacrylate resin, 0 to 25 parts of alkoxylated acrylate, 0 to 25 parts of diluent, 0.1 to 10 parts of photoinitiator, 0 to 5 parts of defoaming agent, 0 to 5 parts of flatting agent and 0 to 5 parts of antioxidant. The bismaleimide / acrylic acid liquid crystal photosensitive resin-based composition provided by the invention is good in printability and has the capability of printing a complex structure; meanwhile, the characteristics of the bismaleimide photosensitive resin and acrylic acid liquid crystal photosensitive resin composition are reserved, and a printed product is excellent in heat resistance and good in mechanical property and can be widely applied to the fields of fine electronic devices, aerospace and the like.

Description

technical field [0001] The invention relates to the field of photosensitive resin processing and its application, especially the composition based on bismaleimide / acrylic liquid crystal photosensitive resin and its application in 405nm 3D printing. Background technique [0002] In recent years, 3D printing technology is in a stage of rapid development, attracting more and more researchers. Compared with traditional manufacturing methods, 3D printing does not need to use molds, which can effectively reduce the production cycle and cost of industrial products. With the development of 3D printing technology, it has been more applied in the fields of aerospace technology, medical engineering, construction industry and electronic manufacturing. Among various types of 3D printing technologies, stereolithography (SLA) stands out due to many advantages such as short curing time, high printing accuracy, energy saving and environmental protection. In addition, the printed articles h...
