Additive manufacturing method and system for light-cured resin matrix composite parts (components)

Abstract

The invention discloses an additive manufacturing method and system for light cured resin matrix composite parts (components). According to the method, the advantages of photosensitive resin and a fiber / particle reinforced composite additive manufacturing technology are organically combined so as to generate the composite parts (components) with high surface accuracy and excellent performance; specifically, the characteristics that the parts (components) formed by a photo-curing technology are high in surface accuracy and are not limited by the structures are utilized; and reinforced composites with different materials, different orientations, different amount and the like can be added according to the design by utilizing a flexible mechanism. The manufacturing method and system have the advantages that the orientations, the contents, the positions and the like of the composites in the parts (components) can be accurately controlled, and therefore the composite parts (components) with high surface accuracy and excellent performance can be rapidly manufactured; the manufacturing method and system are not only suitable for single manufacturing of large-scale reinforced composite parts (components), but also suitable for batch production of small-sized reinforced composite parts (components); and the manufacturing cost can be saved, the production period can be shortened, and the application range of products can be expanded.
