Embodiment Construction

[0045] Such as Figure 1 to Figure 4 The shown multi-nozzle calibration mechanism of a 3D printer includes a nozzle base plate 1, three nozzle bodies are installed on the nozzle base plate 1, and a nozzle matrix 24 is arranged at the bottom of the nozzle body. The nozzle body includes a first nozzle body 2, a second nozzle body 3 and a third nozzle body 4. The first nozzle body 2 and the second nozzle body 3 are located in the same row, and the third nozzle body 4 is located between the first nozzle body 2 and the second nozzle body. Below the nozzle body 3. There will be a certain gap between the printing dot matrix ejected from the first nozzle body 2 and the second nozzle body 3. By controlling the printing time of the nozzle dot matrix 24 of the third nozzle body 4 below, the third nozzle body 4 The ejected printing dot matrix 25 fills these gaps, thereby increasing the printing area and improving the printing efficiency through the printing of the three nozzle bodies.

Abstract

The invention discloses a multi-nozzle calibration mechanism of a 3D printer. The multi-nozzle calibration mechanism comprises a nozzle bottom plate, wherein a plurality of nozzle bodies are arrangedon the nozzle bottom plate, mounting openings are formed in the nozzle bottom plate corresponding to each nozzle body, and each mounting opening is provided with a positioning device for positioning the corresponding nozzle body and an adjustment device used for adjusting the nozzle body. The nozzle calibration method comprises the following steps that a first nozzle body is rotated through a rotating assembly, so that a nozzle dot matrix of the first nozzle body needs to be kept parallel to the direction of the nozzle body in the Y-axis movement along the Y-axis connecting line, and the remaining two nozzle bodies are calibrated by taking the first nozzle body as a reference. According to the multi-nozzle calibration mechanism, the nozzle is calibrated through the multi-nozzle calibrationstructure before the multi-nozzle 3D printer is delivered, so that nozzle bodies are parallel to one another, the error of 3D printing is reduced, and the printing precision is improved.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a multi-nozzle calibration mechanism of a 3D printer and a method for calibrating the nozzles thereof. Background technique [0002] 3D printers build three-dimensional models through additive manufacturing methods. Wax type 3D printer is a kind of additive manufacturing equipment. It uses blue wax as the model material and white wax as the support material. It sprays the high-temperature heated wax onto the printing platform, and builds the model by layer-by-layer stacking. Due to the advantages of high precision and smooth surface of wax-sprayed 3D printing models, wax-sprayed 3D printers are widely used in jewelry, aerospace, engine and other manufacturing industries. The printing materials used in the wax spray 3D printer are white wax and blue wax. The wax is packed in a container, and the container is put into the ink supply assembly. The blue wax in the container fl...
