Multi-spray-head 3D printing system

Abstract

The invention provides a multi-spray-head 3D printing system, and relates to the technical field of aerospace 3D printing. The multi-spray-head 3D printing system comprises a framework, a first printing mechanism and multiple second printing mechanisms. The first printing mechanism and the multiple second printing mechanisms are movably arranged on the framework in the X-axis direction, the Y-axisdirection and the Z-axis direction. The first printing mechanism is arranged vertically downwards. The multiple second printing mechanisms are located below the first printing mechanism and are distributed in a radial shape. The multiple printing mechanisms are arranged in the multi-spray-head 3D printing system, and the problem about the locating datum in various printing directions is solved; specifically, during use, the first printing mechanism and the multiple second printing mechanisms can surrounding printing stations, and the printing mechanisms can cooperate with one another and extrude different raw materials; and the multiple printing mechanisms work at the same time, directional and quantitative control is carried out on the raw materials in the printed state, and 3D printingof high-performance composites is achieved.

Description

technical field [0001] The invention relates to the technical field of space 3D printing, in particular to a multi-nozzle 3D printing system. Background technique [0002] Space 3D printing technology is a research hotspot in various aerospace powers. At present, space 3D printing technology mainly uses thermoplastic polymer materials as printing raw materials, and 3D printing is carried out through fused deposition manufacturing technology. [0003] Existing space 3D printing solutions have the following deficiencies: [0004] 1. At present, the heat transfer method in the 3D printing process under high vacuum conditions mainly relies on thermal radiation, and the temperature of the material is relatively difficult to control; 2. In the current space 3D printing solution, a single nozzle is used to extrude the raw material bar, and then the robot arm will The extruded rods are gradually assembled into a large antenna structure by gluing, while the single-nozzle 3D printing...
