Abstract

The invention relates to an intelligent 3D printer with high printing precision. The intelligent 3D printer comprises a base, a controller, a printing platform, a top plate, a lifting plate, a plane moving mechanism, a printing mechanism and two lifting units; the printing mechanism comprises a material disc, a wire feeding pipe, a heating device, a first flow pipe, a flow guide box, a second flow pipe and a printing head, wherein a flow guide mechanism is arranged in the flow guide box and comprises a second driving motor, a first connecting rod, a second connecting rod, a piston, a flow guide cylinder, a blocking mechanism and two third flow pipes; and a heating mechanism is arranged in the controller and comprises a heating unit and two translation units. According to the intelligent 3D printer with the high printing precision, the translation units are used for driving the heating unit to move to preheat the printing platform in sequence, the electric energy consumption is reduced, and the energy-saving effect is achieved; and moreover, and the material extrusion amount of the printing head is guaranteed each time through the flow guide mechanism, so that the heights of printing layers are equal, and then the precision of a printed sample and the practicability of equipment are improved.

Description

technical field [0001] The invention relates to the field of 3D printing equipment, in particular to an intelligent 3D printer with high printing precision. 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] When the 3D printer is printing, if the first layer of material cannot be attached to the printing platform normally, it will directly affect the later printing. Therefore, before printing, the user not only calibrates the horizontal angle of the printing platform, but also uses a heating pad Heat the printing pl...

Problems solved by technology

[0003] When the 3D printer is printing, if the first layer of material cannot be attached to the printing platform normally, it will directly affect the later printing. Therefore, before printing, the user not only calibrates the horizontal angle of the printing platform, but also uses a heating pad Heat the printing platform to reduce the temperature difference between the platform and the material extruded by the nozzle, and prevent the material from not sticking to the printing platform after shrinking when it is cold. Although this can ensure that the first layer of material is close to the printing platform, heating The way of pad heating usually heats the entire plane of the printing platform, which leads to a lot of power consumption during heating. Not only that, but also in the printing process, due to the uneven thickness of the material filament and the unstable temperature of the nozzle, each The amount of material extruded by the nozzle is uneven at all times, resulting in different layer thicknesses of each layer of the printed sample, making the side edges of the sample uneven and streaked, resulting in uneven and smooth surface of the sample, which affects the printed sample The accuracy of the printer reduces the practicability of the printer
