Embodiment Construction

[0042] The multi-nozzle 3D printer of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] Such as figure 1 The multi-nozzle 3D printer shown includes a printer base 1 and two printing arms 2 installed on the base 1 .

[0044] The structure of the printer base 1 is as figure 2 As shown, it includes a rotating platform 11 , a photoelectric encoder 12 , a first motor 13 , a base 14 and a spindle 15 . Specifically, such as image 3 As shown, the base 14 includes a first bottom plate 142 and a printing arm fixing plate 141 disposed on an upper surface of the first bottom plate 142 . Both the first bottom plate 142 and the printing arm fixing plate 141 are circular plates with the same diameter and arranged coaxially. The first bottom plate 142 has a number of through holes for connection, and the lower end surface of the printing arm fixing plate 141 has a number of screw holes, and th...

Abstract

The invention discloses a multi-nozzle 3D printer based on a rotary platform, and belongs to the technical field of 3D printing. The printer comprises a machine seat and a plurality of printing arms inserted into the machine seat, wherein a rotary platform and a motor for driving the rotating platform are arranged on the machine base, and each printing arm can realize z-direction and radial movement of a printing spray head on each printing arm. The printer adopts a rotary printing mode, the printing route is a polar coordinate, and therefore, the printer is especially suitable for printing arotary body object. Meanwhile, the number of the printing spray heads used by the printer can be adjusted through the number of the inserted printing arms, and the printer is flexible and convenient to use and high in applicability. In addition, the multiple spray heads work together, so that the printing speed can be increased, the printing efficiency can be improved, and the printing time can besaved.

Description

technical field [0001] The invention belongs to the field of 3D printing, and relates to a multi-nozzle 3D printer based on a rotating platform. Background technique [0002] Most of the existing 3D printers use a rotating stepper motor plus a timing belt to realize the movement of the printing nozzle in the X, Y and Z directions, and then realize the cumulative printing layer by layer. However, this type of printer has certain limitations in printing, that is, when printing revolving objects, the surface is often rough and the quality is poor, which is difficult to meet the requirements. Contents of the invention [0003] The invention proposes a multi-nozzle 3D printer based on a rotating platform suitable for printing a rotating body. [0004] The technical scheme adopted in the present invention is: [0005] A multi-nozzle 3D printer based on a rotary platform, comprising a printer base and a plurality of printing arms; the printer base includes a rotary platform, a ...
