Intelligent 3D printing device capable of achieving smooth printing and free of faults

Abstract

The invention relates to an intelligent 3D printing device capable of achieving smooth printing and free of faults. The intelligent 3D printing device comprises a printing sprayer and a plurality of supporting units. Each supporting unit comprises a casing pipe, a supporting rod, a buffer board, a spring and a pressure sensor. A material spraying mechanism, a material pipe, a heating ring and a throat pipe are arranged inside the printing sprayer. The material spraying mechanism comprises a slide bar and material spraying units arranged at the two sides of the slide bar. Each material spraying unit comprises a fourth driving motor, a driving wheel and a plurality of driving teeth. Bar-shaped teeth are arranged at the two sides of the slide bar. According to the intelligent 3D printing device capable of achieving smooth printing and free of faults, the pressure sensors in all the supporting units are used for detecting whether a printed sample moves or not, the printing sprayer is moved to a correct position through a camera and a plane moving mechanism and then printing continues, so that the fault problem happening in the printing process is avoided; and moreover, a liquefied material in the throat pipe can flow out of the printing sprayer through the material spraying mechanism, and therefore printing smoothness is guaranteed, nozzle blocking is avoided, and practicability of the printing device is improved.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to an intelligent 3D printing device with smooth printing and no faults. Background technique [0002] 3D printing device, also known as three-dimensional printing device, is a cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on digital model files and uses special wax, powdered metal or plastic and other bondable materials. Three-dimensional objects are made by layering and bonding materials. At this stage, 3D printing devices are used to manufacture products. Objects are constructed by printing layer by layer, and data and raw materials are put into the 3D printing device. The machine will manufacture products layer by layer according to the program.

Problems solved by technology

[0003] During the printing process of the 3D printing device, the printed samples on the printing platform are easily impacted by external forces, causing the printed samples to move on the printing platform. However, most of the existing 3D printing devices adopt an open-loop control system, that is, the control board does not After receiving the information feedback of the relative position of the printing nozzle and the printing sample, it is simply to achieve single-layer printing by moving the nozzle, resulting in that when the printing sample moves and deviates from the original position during printing, the final printed product is prone to faults problems, which directly lead to printing failure, not only that, but the existing print nozzles usually have the problem of nozzle clogging and inability to spin silk, too many impurities inside the nozzle, too much deposition of consumables in the nozzle or insufficient heat dissipation of the nozzle, all of which will lead to Nozzles are clogged, preventing printing from continuing
