Embodiment Construction

[0031] Such as figure 1 As shown, in the layered cooperative printing method of three nozzles of the present invention, firstly, the left nozzle 3 and the right nozzle 4 are arranged at the same height, and between the left nozzle 3 and the right nozzle 4, there is a layer higher than the left nozzle 3 and the right nozzle 4. An upper nozzle 5 with the thickness of a printing layer is provided with a printing platform below, and the relative distance between the printing platform 14 and the left nozzle 3, the right nozzle 4 and the upper nozzle 5 is adjustable.

[0032] When printing, the specific steps are as follows.

[0033] a. Cut the designed workpiece model horizontally into several layers using slicing software, and the thickness of each layer is consistent with the thickness of the printing layer.

[0034] b. Make path planning for each layer of the workpiece model from bottom to top.

[0035]The three nozzles all move along a straight line. The nozzles first move al...

Abstract

The invention relates to a layered and cooperative printing method with three nozzles. In the three nozzles printing method, the same workpiece model is printed simultaneously by three nozzles, and the left and right nozzles respectively print the left and right regions of the same printing layer, and the upper nozzle The middle area of ​​the upper adjacent printing layer is printed, and the three nozzles are printed in layers, and the printing of the entire workpiece model is completed by adjusting the distance between the nozzles and the printing platform. The three-nozzle 3D printer is a 3D printer specially used to realize this printing method. It can drive three nozzles to move along the X-axis and Y-axis respectively, and can adjust the height of the printing platform to control the distance between the nozzles and the printing platform. The invention is easy to operate, realizes the seamless connection between the partitions through the layered and partitioned printing of three nozzles, avoids mutual interference among multiple nozzles, and doubles the time for printing a single workpiece model.

Description

technical field [0001] The invention relates to a 3D printing technology, in particular to a three-nozzle layered collaborative printing method. Background technique [0002] 3D printing technology is a rapid prototyping technology. It is based on digital three-dimensional model files, and it is a technology that forms objects such as metal, plastic, and photosensitive resin through layer-by-layer printing. It belongs to additive manufacturing. At present, 3D printers based on the principle of Fused Deposition Modeling (FDM: Fused Deposition Modeling) have become the most popular 3D printers due to their simple structure, rich variety of applicable materials, and low cost of equipment and consumables. [0003] The FDM printer melts the printing consumables and extrudes them into filaments, and slowly stacks and deposits them from point to line and then to surface. Therefore, compared with the 3D printing technology of the surface forming process, its printing efficiency is l...
