Embodiment Construction

[0034] Such as figure 1 As shown, it is the front view of the 3D printing Venturi nozzle of the present invention; it includes a gas inlet 101, a conical constriction section 102, a cylindrical throat 103, a heating mechanism 104, a conical diffusion section 105, an extrusion outlet 106, and a feeding The pipeline 107, the inner channel 109 of the material delivery pipeline, and the shrinkage 108 of the material delivery pipeline. Among them, the pressurized gas enters from the inlet 101 and passes through the conical constriction section 102. At this time, the gas flowing at a high speed passes through the cylindrical throat 103. Adsorption takes place. The other end of the throat is connected to the feeding pipeline 107. When passing through the heating mechanism 104, the silk material in the channel 109 in the feeding pipeline will be formed into a molten state. When the low pressure cylindrical throat 103 is reached, it will be absorbed by the air along with the air. Mix...

Abstract

The invention relates to the technical field of 3D printing equipment, in particular to an FDM3D printing achieving method, a printing system and a jet flow control method under the space environment. A glue sprayer and a pressurizing sprayer are arranged, the glue sprayer sprays a layer of glue in the program assigned area, and then the pressurizing sprayer melts hot melting wires and increases conveying. After the molten spraying wires are extruded out, bonding forming is carried out under the microgravity state. The flow of molten spray wires and the extruding bonding forming process are controlled by controlling the movement of the pressurizing sprayer. Accordingly, solid printing is achieved. The 3D printing purpose under the microgravity space environment is achieved. The FDM3D printing achieving method, the printing system and the jet flow control method can be used for 3D printing under the space environment.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to an FDM 3D printing implementation method, a printing system and a spinneret flow control method suitable for space environments. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is based on the layered discretization of 3D digital models through software, and is formed by cumulative manufacturing technology. The advantages of 3D printing are: manufacturing complex items does not increase the cost, and can print complex parts required in spaceships; 3D printing technology belongs to the category of additive manufacturing, which saves materials compared with traditional manufacturing and minimizes the demand for printing materials for space mission parts; Enables exact physical duplication by creating exact copies or optimizing originals, while simultaneously performing the tasks of scanning, editing, and duplicating physical obj...
