Intelligent 3D printer with anti-drawing function

Abstract

The invention relates to an intelligent 3D printer with an anti-drawing function. The intelligent 3D printer with the anti-drawing function comprises a base, a printing platform, a top plate, a material tray, a wire feeding pipe, a lifting plate, a printing unit and two lifting units. The printing unit comprises a horizontal movement plate, a supporting unit, a printing sprayer, a plugging plate and two drive units. Each drive unit comprises a second drive motor, a second drive shaft, a telescopic unit and a heat dissipation unit, wherein the telescopic unit comprises an air pump, an air pipe, an air cylinder and a piston; and the heat dissipation unit comprises a third drive motor, a third drive shaft and a plurality of blades. According to the intelligent 3D printer with the anti-drawing function, the plugging plate is moved to the position below the printing sprayer through the drive units and moved upwards to block the printing sprayer, so that materials are prevented from flowing out, and drawing is avoided; and besides, heat dissipation and cooling are conducted on the printing sprayer through the heat dissipation units, so that the materials easily adhere to the inside of the printing sprayer and are not prone to being extruded out, drawing is further prevented, and practicability of the printer is improved.

Description

technical field [0001] The invention relates to the field of 3D printing equipment, in particular to an intelligent 3D printer with an anti-drawing function. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of accumulative manufacturing technology, that is, a machine of rapid prototyping technology. Layers of bonded material are used to create three-dimensional objects. At this stage, 3D printers are used to manufacture products. Objects are constructed by printing layer by layer, and data and raw materials are put into the 3D printer. The machine will manufacture products layer by layer according to the program. [0003] During the printing process of existing 3D printers, there is often the problem of stringing, which is the residual thread-like objects left when the extruder crosses the open space. In order to avoid wire drawing, the method of material withdrawal is usually adopted, that is, before the nozzle moves to the next...

AI Technical Summary

Problems solved by technology

Although it can be avoided in theory, there will still be wire drawing problems in the actual process, especially in the four situations of insufficient retraction distance, too slow retraction speed, too high nozzle temperature and too long suspension moving distance. Part of the consumables will still flow out of the nozzle, so that the drawing problem cannot be completely solved, resulting in printing failure
