A multi-material molding device with a powder control baffle and its 3D printing method

Abstract

The invention discloses a multi-material molding device with a powder control baffle and a 3D printing method thereof, including a powder supply mechanism, a powder spreading mechanism and a powder collection mechanism with a retractable powder control baffle, and the powder supply mechanism is installed on The two sides of the powder spreading mechanism are used to provide the powder spreading mechanism with the powder materials required for printing multi-material molded parts; a molding cavity is formed inside the powder spreading mechanism, and a retractable powder control baffle is set above the forming cavity, which can Out or retract, the amount of powder of different materials in the molding cavity is controlled through the retractable powder control baffle, so as to realize the quantitative powder coating of multi-material molded parts. The powder control baffle can be flexibly deformed according to the shape of the molded parts, Realize the printing of multi-material and irregular moldings; the powder collection mechanism is used to recover the residual powder in the molding cavity. The invention effectively solves the problem of powder mixing of multiple materials in the molding cavity, and the problem of a large amount of powder spreading of a single material after printing a large molded part to a certain height.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a multi-material forming device with a powder control baffle and a 3D printing method thereof. Background technique [0002] In recent years, the rapid development of 3D printing has attracted widespread attention from the society. 3D printing technology, also known as additive manufacturing technology, can quickly manufacture various structurally complex parts based on three-dimensional models. 3D printing technology enables the structural design of parts to be free from the limitations of traditional manufacturing techniques, and improves the manufacturing capabilities, especially metal 3D printing. Metal 3D printing is the most cutting-edge and potential technology in the entire 3D printing system. An important development direction of advanced manufacturing technology. With the development of 3D printing technology, multi-material molded parts are now a major developmen...
