Universal movement mechanism of 3D printer

Abstract

The invention discloses a universal movement mechanism of a 3D printer. The universal movement mechanism of the 3D printer comprises a mechanism top, a mechanism bottom, a material extrusion device and a workbench. The workbench is arranged between the mechanism top and the mechanism bottom, and the material extrusion device is placed above the upper surface of the workbench. Three sets of universal rotating components and three sets of transmission components are further included, and the transmission components are sleeved with sliding blocks which can slide up and down. The three sets of transmission components are installed between the mechanism top and the mechanism bottom at intervals. The sliding blocks are connected with the material extrusion device through the universal rotating components and the material extrusion device. According to the universal movement mechanism of the 3D printer, only the Z-axis direction is reserved, by the aid of the scheme, the printing speed can be increased substantially, and moreover due to the fact that two axial movements are reduced, the problems of resonance and noise are solved.

Description

Technical field [0001] The invention relates to a 3D printer, in particular to a universal movement mechanism of the 3D printer. Background technique [0002] With the continuous progress of 3D printing technology, people have put forward higher requirements for the function, performance and reliability of 3D printers. For desktop 3D printers, there is still much room for improvement in the fineness of printed objects. [0003] Prior to printing, the existing 3D printer uses the traditional XYZ three-axis motion scheme, which has the disadvantages of slow printing speed, high resonance noise, and poor three-axis stability. The printed objects will have certain errors, resulting in reduced printing accuracy. . [0004] Moreover, the working table needs to adjust its position before printing on the 3D printer. When the workbench is adjusted, the surface of the workbench will be tilted and not level enough. Therefore, there will be certain errors in the printed objects on the workbe...

AI Technical Summary

Problems solved by technology

When adjusting the workbench, it will cause the table top of the workbench to tilt, which is not level enough

Therefore, there will be a certain error in the actual object printed on the workbench, and such errors are difficult to avoid, and it is easier to affect the precision of the printed object
