Problems solved by technology
Long-term vibration of 3D printers will cause parts to loosen, reducing the surface quality and dimensional accuracy of printed parts
At the same time, the 3D printer will also generate certain noise due to vibration during the working process, which will pollute the working environment.
Most of the existing 3D printers use rubber damping blocks on the base to attenuate vibration, but the cushioning effect cannot fully meet the shock absorption requirements of high-precision 3D printers

The invention provides a 3D printer active-type three-dimensional damping device and a using method thereof. Through the mutual effect of electromagnetic fields generated by five pairs of electromagnetic coils, the damping function of a 3D printer body can be achieved in a three-dimensional space; when vibration occurs, a PID control method is adopted, the current intensityin the electromagnetic coils is actively adjusted, thus the 3D printer body rapidly restores to a balanced position under the effect of electromagnetic force, and the disturbance influence is overcome; in the printing process, the 3D printer body suspends in air under the effect of the electromagnetic force, and thus transmission of vibration of the outside world can be prevented; and the 3D printer body is detachably connected with a connecting module, thus the 3D printer active-type three-dimensional damping device and the using method thereof are universal and suitable for damping of 3D printers of different models. Through the 3D printer active-type three-dimensional damping device and the using method thereof, vibration generated in the work process of the3D printercan be effectively reduced, the influence of vibration of the outside world can be isolated, the printing accuracy is improved, and noise is reduced.
Description
technical field [0001] The invention belongs to the technical field of 3D printers, and in particular relates to an active three-dimensional damping device for a 3D printer and a method for using the same. Background technique [0002] 3D printing technology is a kind of additive manufacturing technology. First, use computer-aided design software to establish a three-dimensional model of the printed object, and then "partition" the three-dimensional model into layer-by-layer sections, that is, slices. The 3D printer reads the data information of the slices, prints these slices layer by layer with liquid, powdery or molten materials, and superimposes and bonds them together to create a printed entity. [0003] During the working process of the 3D printer, when the moving device in the X and Y axes moves rapidly, if the speed or direction of the displacement changes suddenly, low-frequency vibration will be generated due to inertia. In addition, if the anti-vibration measures...
