Method for generating 3D printing data, path planning method, system and storage medium

A non-transitory computer-readable storage medium, wherein at least one program is stored on the storage medium, and when the at least one program is called by a processor, the at least one program executes and realizes a method for generating 3D printing data, wherein the method comprises:

• slicing a model of a to-be-printed object into multiple horizontal layers;
• for each of the horizontal layers:
• projecting the to-be-printed object onto a plane corresponding to said layer to obtain a projected contour of said layer, wherein, the projected contour refers to a projection of a contour of the to-be-printed object;
• generating at least two single-layer texture planes, wherein each single-layer texture plane includes at least one texture line;
• adjusting spatial positions of the at least two single-layer texture planes so that their projections onto a same plane partially overlap, to obtain a multi-layer texture plane;
• generating at least one slice pattern through cutting the texture plane by the projected contour, wherein each slice pattern comprises one or more texture lines, and the one or more texture lines comprise non-closed texture lines whose endpoints are located on the projected contour;
• generating the 3D printing data based on spatial positions of printing lines of cross-sectional patterns, with the cross-sectional patterns determined based on the at least one slice pattern, wherein a first cross-sectional pattern is determined based on a first slice pattern of the at least one slice pattern, the first cross-sectional pattern comprises one or more printing lines, and the first slice pattern comprises first texture lines;
• wherein the printing lines comprise the first texture lines;
• generating G-codes based on the 3D printing data;
• and
• printing the to-be-printed object layer by layer by a 3D-printer using the G-codes.
