Problems solved by technology

At present, most of the 3D printing technology stays under the process conditions of single powder forming. In the printing process, different powders are suitable for different process parameters, especially metal powders can be effectively sintered and formed under specific process parameters. The final metal powder process parameters are extremely difficult to find, but different materials have different metal properties, and the existing 3D printing devices cannot realize the simultaneous application of different materials

Abstract

The invention relates to a dual-powder mixing printing system for 3D printing. For an existing 3D printing system, a powder A cylinder (4) and a powder B cylinder (5) are arranged at the two sides ofa forming cylinder (3) in a sealing box (1) respectively, in cooperation with scraper systems designed for the powder cylinders respectively, on the basis of a laser device (2), alternate 3D printingbetween two kinds of powder is achieved, meanwhile, a powder A collecting cylinder (6) is introduced at the position between the powder A cylinder (4) and the forming cylinder (3), and a powder B collecting cylinder (7) is introduced at the position between the powder B cylinder (5) and the forming cylinder (3), the powder in the corresponding powder cylinders is scraped into the forming cylinder(3) through scrapers (12) in the scraper systems, and then surplus powder is scraped into the corresponding powder collecting cylinders; the surplus powder can be recycled, the powder obtained after layers of 3D printing is not mixed, the powder can be used secondarily, the advantages of the two kinds of powder are achieved, and the metal performance of forming materials is effectively improved.

Description

technical field [0001] The invention relates to a dual-powder mixed printing system for 3D printing, belonging to the technical field of 3D printing systems. Background technique [0002] 3D printing technology is a rapid prototyping technology based on digital model files, which uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. At present, most of the 3D printing technology stays under the process conditions of single powder forming. In the printing process, different powders are suitable for different process parameters, especially metal powders can be effectively sintered and formed under specific process parameters. The final metal powder process parameters are extremely difficult to find, but different materials have different metal properties, and the existing 3D printing devices cannot realize the simultaneous application of different materials. Contents of the invention [0003] The technical problem to be s...
