Embodiment Construction

[0012] The technical solutions in the embodiments of the present invention will be described clearly and in detail below with reference to the drawings in the embodiments of the present invention.

[0013] Such as figure 1 As shown, the present invention provides a 3D printer slicing contour path planning algorithm, comprising the following steps: first, an optimized shortest distance algorithm is used to determine the starting point of each closed loop contour in the slicing process, as the connection point of the 3D printing sequence, The goal should be to keep the distance between each starting point as short as possible. Then the single variable method is used to determine the initial parameter value of the ant colony algorithm. Finally, the ant colony algorithm and genetic algorithm are combined, and the improved ant colony algorithm is used to plan the path of the determined printing starting point, and the optimal printing path is obtained.

[0014] The specific steps...

Abstract

The invention relates to protect a 3D printer slice contour path planning algorithm. According to the 3D printer slice contour path planning algorithm, firstly, an optimized shortest distance algorithm is adopted to determine starting points of all closed loop contours in the slicing process, the starting points serve as connecting points of a 3D printing contour sequence, and the target of the algorithm is to shortens the distance between the starting points as much as possible; secondly, an initial parameter value of the ant colony algorithm is determined by adopting a single variable method; and thirdly, path planning is carried out on the determined printing starting point by utilizing an improved ant colony algorithm, so as to obtain an optimal printing path. According to the 3D printer slice contour path planning algorithm, the optimal printing sequence is planned by reasonably selecting the printing starting point of each closed loop contour, so that the 3D printing efficiency is improved, and the printing time is shortened.
