AI Technical Summary
Technical Problem
In existing 3D printing technology, there is a problem where material leakage after the print head stops extruding leads to a decrease in the surface quality of the finished product.
Method used
By planning the printing path and controlling the speed and direction of the print head, the tail material is made into filaments, and the print head is lifted at a safe end point to avoid the tail material affecting the quality of the outer surface.
Benefits of technology
It improves the surface quality of 3D printed products and prevents the adverse effects of material overflow and filament pulling on the finished product.

Abstract
The application discloses a method, device and storage medium related to 3D printing path planning, and belongs to the technical field of 3D printing. The method comprises the following steps: acquiring a printing path, closing an extrusion signal of a printing head when the printing head moves to a preset point of a first printing path; increasing the printing speed of the printing head to a preset printing speed and moving the printing head to a preset direction of a second starting point of a second printing path; after the printing head moves a preset distance in the preset direction, lifting the printing head upward to a safe ending point of the first printing path; determining a safe starting point of the second printing path, moving the printing head to the safe starting point of the second printing path, and continuing to perform a printing action. The technical problem that the processing of tail material of a related scheme affects the surface quality of a 3D printing product is solved, so that the surface quality of the 3D printing product is improved by controlling the tail material drawing through speed change.
