The invention discloses a scanning line quality optimization method. The method comprises the steps that the invalid starting length and the invalid termination length of each scanning line are obtained; scanning line information of each horizontal section layer of a workpiece to be machined is obtained, each horizontal section layer is divided into multiple areas, and each area comprises multiple scanning lines; the scanning line information includes the lengths of the scanning lines; and the scanning lines are optimized according to the lengths of the scanning lines, the invalid starting lengths of the scanning lines and the invalid termination lengths of the scanning lines. The invention further provides a scanning line quality optimization device and a printer. The situation that the energy of a local area of a printed piece is too high can be avoided.
Description
technical field [0001] The invention relates to the technical field of laser forming, in particular to a scan line quality optimization method, a scan line quality optimization device and a printer. Background technique [0002] In order to alleviate defects such as warping, cracks and pores of the printed part, the printed part model will be sliced to form horizontal section layers before printing, and each horizontal section layer will be scanned according to checkerboard, bar, rotation vector line and other scanning strategies Plan the scan path. The scan lines formed after planning the scan path may be long or short. When performing 3D printing, some short scanning lines are in the process of accelerating to decelerating during laser light scanning, and often the scanning ends before the acceleration reaches the preset value. In this way, in order to melt the powder to be formed, the laser power required for a short scanning line is high, which will lead to excessive...
