Problems solved by technology

[0003] The existing 3D printers can only achieve single nozzle or multi-nozzle single nozzle due to the structural design. Today, in the pursuit of efficiency, it seriously affects the speed of 3D printing and limits the efficiency of 3D printing. Therefore, there is an urgent need for a multi-nozzle. The structure of the 3D printer that prints simultaneously with nozzle co-spraying improves the printing speed of the 3D printer
[0004] The accuracy of existing 3D printers is generally not high, and the accuracy is even worse when the printing trajectory is a curve, which makes the existing 3D printers unsuitable for printing shaft and rotary parts, so a class of 3D printers is urgently needed to fill the gap

Embodiment Construction

[0042] Below in conjunction with example and accompanying drawing, this technical scheme is further described:

[0043] Refer to attached Figure 1-7 , a cylindrical coordinate 3D printer capable of simultaneously printing with multiple nozzles includes an external meshing precision planetary gear mechanism (1), a retractable cantilever beam mechanism (2), a Z-axis motion mechanism (3), and a feeding mechanism (4).

[0044] The external meshing precision planetary gear mechanism (1) consists of a sun gear (1-1), a planetary gear (1-2), a support block (1-3), a reinforcing ring (1-4) and a disc-shaped working Taiwan (1-5) constitutes. There are at least two planetary gears (1-2) described above. This example takes a double print head as an example, so there are two planetary gears, namely planetary gear A (1-2A) and planetary gear (1-2B). B (1-2B). Among them, the sun gear (1-1), the reinforcement ring (1-4) and the disc-shaped workbench (1-4) are fixed on the support block ...

Abstract

The invention relates to a cylindrical coordinate type 3D printer capable of achieving simultaneous multi-spray-head printing. The printer comprises an external gearing precision planetary gear mechanism, a telescopic cantilever beam mechanism, a Z-axis movement mechanism and a feeding mechanism. The external gearing precision planetary gear mechanism is composed of a sun gear, a planetary gear, a supporting block, a reinforcing circular ring and a disc-shaped workbench. The telescopic cantilever beam mechanism comprises a spray head, a feeding motor, a Z-axis movement block, a polar axis driving motor, a polar axis ball screw and a limiting block. The Z-axis movement mechanism comprises a Z-direction driving motor, a Z-direction movement mechanism supporting frame, a Z-direction ball screw, a planetary gear driving motor and a motor base. The feeding mechanism comprises a feeding wheel and a feeding wheel supporting frame. Polar coordinate plane printing is achieved through the external gearing precision planetary gear mechanism and the telescopic cantilever beam mechanism, and Z-direction movement is achieved through a Z-axis control mechanism, so that three-dimensional printing movement of spray heads is achieved; by means of multi-layer multi-telescopic-arm cooperation, simultaneous multi-spray-head machining is achieved.

Description

technical field [0001] The present invention relates to a cylindrical coordinate 3D printer capable of simultaneously printing with multiple nozzles. In order to solve the problem that the nozzles of the current multi-nozzle 3D printer are prone to interference and that the multi-nozzle printer can only have one nozzle working at most at the same time , and the problems of slow speed and low precision of printing rotary parts by 3D printers at present, the structure of this 3D printer is proposed. technical background [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. [0003] The existing 3D printers can only achieve single nozzle or multi-nozzle single nozzle due to the structural design. Today, in the pursuit of efficiency, it seriously affects the speed of 3D printing and limits the efficiency of 3D p...
