Problems solved by technology

The 3D printing model in the prior art sometimes contains some symmetrical elements, and even the whole model is a symmetrical structure. When printing this kind of three-dimensional model, the nozzle prints a section and repeats the same path several times, which not only affects printing efficiency, but also And it will increase the complexity of programming to a certain extent

Abstract

The invention belongs to the technical field of 3D printing and particularly relates to a 3D printer. The 3D printer comprises a rotating sprayer assembly, wherein the rotating sprayer assembly comprises a connecting part and a rotating part, the connecting part is used for connecting a sprayer driving mechanism of the 3D printer, and the rotating part is arranged at the connecting part along the vertical axis in a rotating manner; at least two sliders are arranged at the rotating part, each slider is arranged at the rotating part in a sliding manner in the radial line direction of a circular region which takes the rotating center of the rotating part as a circle center, and the sliders are arranged in a manner of making synchronous symmetrical motion with the rotating center of the rotating part as a symmetrical point; and a sprayer is separately mounted on each slider, and the sprayers are symmetrically arranged with the rotating center of the rotating part as the center. As the 3D printer comprises at least two sprayers making synchronous symmetrical motion, a symmetrical structure on a model can be synchronously printed in the printing process, the printing time of the model is greatly shortened, and at the same time, the encoding process is effectively simplified.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file and uses special wax, powdered metal or plastic to bond materials, which create three-dimensional objects by printing layers of adhesive materials. At this stage 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. The 3D printing model in the prior art sometimes contains some symmetrical elements, and even the whole model is a symmetrical structure. When printing this kind of three-dimensional model, the nozzle ...
