Abstract

The invention discloses a composite fast forming production device and preparation method. The device comprises a weaving machine rack. An ultraviolet light transmitter and a photocuring 3D printer are sequentially mounted on the weaving machine rack from top to bottom. A liquid containing tank is formed in the bottom face in the photocuring 3D printer. A row of horizontal shooting-in holes and arow of vertical shooting-in holes are formed in the inner wall of the photocuring 3D printer. A lifting device is mounted at the position, below the horizontal shooting-in holes and the vertical shooting-in holes, of the bottom face in the liquid containing tank. A printing platform is mounted on the lifting device and also located below the horizontal shooting-in holes and the vertical shooting-in holes. The inner side wall faces of the periphery of the top of the photocuring 3D printer are each provided with a plane mirror. According to the composite fast forming production device and preparation method, the problem that strength obtained after photosensitive resin forming is insufficient is effectively solved; and compared with a traditional composite machining method, the production period is shortened, and the production technological process of products is reduced.

Description

[0001] technical content [0002] The invention relates to a composite material rapid prototyping production device and a preparation method. Background technique [0003] 3D printing rapid prototyping technology is a new molding technology developed in the 1980s. After more than 30 years of development, the current 3D printing technology mainly includes FDM (Fused Deposition Manufacturing), LOM (Laminated Object Manufacturing), SLS (Laser Selective Sintering) ), SLA (stereolithography), etc. The use of 3D printing technology to prepare molded parts no longer needs to rely on molds and cutting tools, which simplifies the production process, shortens the production cycle, and reduces production costs. However, the biggest defect of 3D printing consumables is their poor strength, which limits the application of molded parts. Woven plain weave is the most common and simplest fabric weave. Fabrics made of plain weave usually have high strength and are not easily damaged. The i...
