Abstract
The invention discloses a method for laser additive manufacturing of components and a laser additive manufacturing system, and relates to the technical field of additive manufacturing, so as to solve the problems caused by different specific gravity and long-term, long-term and long-term problems when pre-mixed powder is coaxially fed with laser deposition for additive manufacturing. The phenomenon of airborne transport segregation and separation of weight and light occurs before reaching the molten pool, which leads to the problem of uneven distribution of components in the composite material formed by laser deposition. The method applies laser additive manufacturing equipment. The method includes that the powder feeder controls the different material powder flows output by the at least two powder feeding tanks to converge at the same position on the substrate surface according to the additive manufacturing strategy of the component, so that the different material powder flows output from the at least two powder feeding tanks The mixture is formed on the surface of the substrate; the laser controls the laser processing head to melt and sinter the mixture according to the additive manufacturing strategy of the component to obtain the component. The method for laser additive manufacturing of components and the laser additive manufacturing system provided by the present invention are used for additive manufacturing.
Description
technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a method and a laser additive manufacturing system for a laser additive manufacturing component. Background technique [0002] Laser additive manufacturing technology is an automated forming technology developed by integrating the latest technologies such as computer, numerical control, laser and new materials. It can discretize complex three-dimensional structures into a series of layers for processing, which greatly reduces the difficulty of processing. [0003] At present, various components required by composite materials can be processed into composite material components by coaxial powder feeding laser deposition technology. However, when the existing coaxial powder feeding laser deposition technology is used to additively manufacture composite material components, there are some The problem of uneven distribution of internal components leads to a serious im...
