Embodiment Construction

[0031] Such as figure 1 As shown, it is the front view of the 3D printing piston pressurized nozzle of the present invention; it includes a delivery pipeline shrinkage 101, a delivery pipeline inner channel 102, a delivery pipeline 103, a piston 104, a heating mechanism 105, and a delivery tube Road 106, extrusion outlet 107, mechanical drive 108. Among them, the working principle of the piston booster pump is similar to that of a pressure booster, which applies a very low pressure to the large-diameter driving piston 104 , and generates a high pressure when the pressure acts on a small-area passive piston 104 . The material enters through the passage 102 in the feeding pipeline, as shown by the dotted line in the figure; the connecting rod of the piston 104 is hollow, and runs through the passage 102 in the feeding pipeline in the middle (that is, the passage in the feeding pipeline runs through the hollow connecting rod Inside), the filamentous material is driven by an exte...

Abstract

The invention relates to the technical field of 3D printing equipment, in particular to a 3D printing achieving method, a printing system and a jet flow control method under the microgravity environment. A glue sprayer and a pressurizing sprayer are arranged, the glue sprayer sprays a layer of glue in the program assigned area firstly, 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 3D 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 a 3D printing realization method, a printing system and a spinneret flow control method suitable for a microgravity environment. Background technique [0002] 3D printing is a form of additive manufacturing technology. The design process of 3D printing is: first use computer modeling software to model, and then "partition" the built 3D model into layer-by-layer sections, that is, slices, so as to guide the printer layer by layer. Print. The advantage of 3D printing is that it realizes the net shape of the first product, so that the amount of auxiliary processing in the later stage is greatly reduced, and the data leakage and time span of outsourcing processing are avoided. It is especially suitable for some industries with high confidentiality, such as military industry and aerospace. and other fields. Manufacture of complex items does not increase the cost, and t...
