Multi-nozzle 3D printer parallel printing method

Abstract

The invention discloses a multi-nozzle 3D printer parallel printing method. Efficient collaborative printing of a multi-nozzle 3D printer is achieved. The method comprises the steps that a model fileis analyzed, supports are added, the model file is sliced to generate a printing cross section, the cross section is partitioned, printing path planning is carried out, and printing is conducted according to a planned path. According to the multi-nozzle 3D printer parallel printing method, through the method of conducting partitioning based on the printing cross section, a printing time estimationalgorithm is combined, thus, the printing capacity of all nozzle assemblies can be sufficiently utilized, and the large-size 3D printing efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and in particular relates to a method for parallel printing of a multi-nozzle 3D printer. Background technique [0002] 3D printing technology is a kind of rapid prototyping technology. It is based on digital three-dimensional model files. It is a technology of forming objects by layer-by-layer printing of metal, plastic, photosensitive resin and other forming materials, which 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] FDM printers are formed by melting and extruding printing consumables into filaments, and then slowly stacking and depositing from point to line to surface. Therefore, compared with the 3D printing technology of surface...

Problems solved by technology

[0008] The biggest defect of this solution is that it only considers the physical size of the nozzle, and idealizes the X and Y axis motion mechanisms that drive the nozzle to a line with a width of 0. The partition scheme does not consider possible problems caused by the motion mechanism. Therefore, if this scheme is to be implemented, the driving mechanism of the sprinkler head can only be a structure similar to a series manipulator, and there are many restrictions on the placement position

Therefore, the implementation is complicated, the cost is high, and the practicability is not ideal

[0009] From the above analysis, it can be seen that the multi-nozzle parallel printing scheme in the prior art is not very ideal
