Problems solved by technology

The traditional path planning method usually prints according to a pre-planned regular path. For complex 3D printing components, due to the frequent jumps of the print head during the printing process, too many printing breakpoints are generated, which leads to the failure of the 3D printing components. Poor molding quality
And because the 3D printer under the traditional path planning will frequently raise the nozzle, it will seriously prolong the molding time of 3D printing

Embodiment Construction

[0038] The present invention is described in further detail below in conjunction with embodiment.

[0039] refer to figure 1 , the specific steps of the present invention are described in detail.

[0040] Step 1: Slicing the printed model.

[0041] Step 1: In the acquisition process of this method, the geometric data (length, width, height, etc.) of the printing member is first read out using a measuring tool, then a printing model is established based on the collected data, and finally the established model is sliced ​​using Cura software.

[0042] Step 2: Convert the sliced ​​model into a geometric model.

[0043] Said step two: (1) delete the information in the slice model that does not need to be printed; (2) extract each geometric point in the slice model; (3) reduce the geometric data of the slice model collected in proportion , making the established geometric model easy to handle. Such as figure 2 .

[0044] Step 3: Initialize the position information of the geo...

Abstract

The invention discloses a path optimization method for concrete 3D printing. The path optimization method comprises following steps: step 1, slicing a printed piece model; step 2, converting the sliced model into a geometric model; step 3, initializing position information of geometric points in the geometric model, and dividing the geometric model into a plurality of areas which can be printed at a time according to a graph theory principle; and step 4, finding out a shortest printing path by adopting an ant colony algorithm. According to the method, the scanning sequence and the scanning starting point of each contour are reasonably planned, inflection points of a contour path in the 3D printing and scanning process are reduced, the idle stroke of the contour path is shortened, and the forming speed and quality are improved.

Description

technical field [0001] The invention belongs to the technical field of concrete 3D printing, and in particular relates to a path optimization method for concrete 3D printing. Background technique [0002] The current concrete 3D printing technology still has many defects. The traditional path planning method usually prints according to a pre-planned regular path. For complex 3D printing components, due to the frequent jumps of the print head during the printing process, too many printing breakpoints are generated, which leads to the failure of the 3D printing components. Poor molding quality. And because the 3D printer under the traditional path planning will frequently raise the nozzle, the molding time of 3D printing is seriously prolonged. Contents of the invention [0003] In order to overcome the deficiencies in the prior art above, the object of the present invention is to provide a path optimization method for concrete 3D printing. The method first establishes the...
