Embodiment Construction

[0021] The following describes the 3DP printing method of the present invention combining the layered dislocation printing and the layered image segmentation method with a specific embodiment in conjunction with the accompanying drawings.

[0022] In this embodiment, the 3DP printing method combining the layered dislocation printing and layer-map-width segmentation method is implemented according to the printing process shown in Figure 1.

[0023] The first step is to read the 3D printing model data information file, load the printing information, analyze the layered information of the 3D model, and obtain the total number N of layers.

[0024] The second step is to judge the printing layer, load the current printing layer from the first layer, and judge whether the number of printing layers i of the current layer is less than the total number of layers N, if i>N is false, exit the printing process, and the printing is over; if i≤ N is True, then enter the third step to execut...

Abstract

The invention relates to a 3DP printing method combining hierarchical shifting printing and layered sheet partition method in the technical field of 3D printing. In the 3DP printing method provided bythe invention, in each layer of printing, a printing head adopts a way of shifting printing layer by layer, so as to enable the same orifices are staggered in the corresponding position in every adjacent layers, thereby avoiding defects of printing module section breaking caused by blockage of multiple orifices or belated repairing; when performing printing in each layer, cutting the whole sheetinto multiple respectively printed sheet according to the width of the printing, and re-planning the treading trace of the printing head, realizing fast blocking on each layer of printing sheet blankarea, so as to improve the printing efficiency. Therefore, according to the invention, printing by using the printing head for hierarchical shifting printing and cutting each layer of printing sheet and re-planning the treading trace, high efficient and fast printing can be realized, the defect of printing section breaking caused by blockage of multiple orifices is avoided, the maintenance cost ofthe printing head is reduced, the service life of the printing head is prolonged.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3DP printing method combining layered misalignment printing and a layer-map-width segmentation method. Background technique [0002] 3DP printing technology uses extruded inkjet printing nozzles for printing. During the printing process, when the individual scattered nozzle holes of the printing head are blocked or damaged, it will cause broken joints that cannot eject the adhesive during the entire printing process. As a result, the entire printed model cannot be formed. This kind of problem requires repair or replacement of the print head, which increases the cost. At the same time, the cross-section of each layer of two-dimensional data model formed in the printing process has a fixed size, and the entire map loaded by the printing control system is used as the printing area, which cannot effectively control the rapid movement of the nozzle in the non-pictured part, whi...
