Abstract

The invention provides a 3D printing method and a powder feed printing mechanism thereof. The powder feed printing mechanism comprises a funnel type cylinder body. A powder outlet of the funnel type cylinder body is in a long strip shape. Elastic scraping plates which are driven by motors and can move up and down are symmetrically arranged on the two sides of the powder outlet correspondingly. A valve controlled by the motors to be opened and closed is arranged at the powder outlet of the funnel type cylinder body. A part model is designed through three-dimensional software, and parts of different materials are identified; then slicing and layering treatment is carried out, and one kind of needed powder is reserved in each of a powder cylinder and the funnel type cylinder body; and a control system controls the powder feed printing mechanism to provide powder for a forming cylinder according to the outline information of slices, the powder is sintered through laser melting, and therefore processing of one layer is completed. The 3D printing method and the powder feed printing mechanism thereof have the beneficial effects that operability is high, and production efficiency is high.A computer recognizes materials required by the parts, the control system controls the powder feed printing mechanism to provide powder for the forming cylinder through a servo motion system accordingto the outline information of the slices, and 3D printing manufacturing of the composite parts can be achieved.

Description

technical field [0001] The invention relates to a 3D printing method and a paint feeding mechanism thereof. Background technique [0002] Compared with traditional machining such as turning, milling, planing and grinding, metal 3D printing, as an additive manufacturing method (Addictive Manufacturing), can manufacture various complex structures and give full play to the efficiency of materials. It is one of the main methods of green manufacturing in the future. Its advantage lies in expanding the space for product creativity and innovation. Designers are no longer constrained by traditional craftsmanship and manufacturing resources, and reduce product R&D innovation costs, shorten R&D cycles, and enhance process manufacturing capabilities. Therefore, in aerospace, biomedical, industrial molds, automobiles, etc. Manufacturing and other industrial fields have unique application prospects, especially in small-batch and multi-variety aerospace applications and personalized medic...
