Problems solved by technology
Common desktop-level 3D printers are gantry-type three-coordinate 3D printers, which have been widely used for their structural stability and long-term performance. The space is larger, the weight is heavier, and more power sources are required at the same time, which cannot achieve better energy-saving effects and meet human requirements for space.

The invention discloses a cantilever type polar coordinate feeding 3D printer. The cantilever type polar coordinate feeding 3D printer is composed of three parts including a 3D printer seat, a rotating arm mechanism and an electric push cylinder; the 3D printer seat is installed on the upper part of a base, the rotating arm mechanism is installed on a cantilever stretching out from the 3D printerseat, the electric push cylinder is installed on the other side of the base, and the cantilever type polar coordinate feeding 3D printer is formed. According to the cantilever type polar coordinate feeding 3D printer, polar coordinate movement of the cantilever type 3D printer is controlled through motors to realize the optimization of the volume structure of a desktop 3D printer, the weight of aprinting head is reduced, the printing precision is improved, and the printing efficiency is improved by direct driving by the motors; and the cantilever type polar coordinate feeding 3D printer has the advantages that the stability and the reliability are achieved, the space occupancy rate is low, and the printing is continuous and accurate, and later maintenance is convenient.
Description
technical field [0001] The invention belongs to the technical field of 3D printing, and relates to a cantilever type polar coordinate feeding 3D printer, which can realize desktop-level 3D printing equipment. Background technique [0002] In the field of 3D printing technology, desktop 3D printers have gradually become popular in human life. With the improvement of human life, the requirements for printers are also increasing, such as the speed of 3D printing, the variety of printing, and the 3D printers. Occupied space issues, etc. Common desktop-level 3D printers are gantry-type three-coordinate 3D printers, which have been widely used for their structural stability and long-term performance. The space is larger, the weight is heavier, and more power sources are required at the same time, which cannot achieve better energy-saving effects and meet human requirements for space. [0003] Therefore, a cantilever-type polar coordinate feeding 3D printer is designed. The movem...
