Abstract: A 3D printing method implemented by swaths is disclosed. When printing swaths of a printing layer, a 3D printer first obtains a default swath-width, and adjusts the default swath-width based on a shift value, then controls a nozzle to print the swaths according to the adjusted swath-width. When printing a final swath of the same printing layer, the 3D printer compensates a remained swath-width of the final swath according to the adjusted shift value(s) of previous printed swath(s), and controls the nozzle to print the final swath according to the compensated remained swath-width. When printing different printing layers, the 3D printer uses different shift values to adjust the swath-width of each printing layer. Because swaths of different printing layers have different widths, the positions of seams between each two swaths of each printing layer are staggered, and thus the strength of printed 3D models is enhanced.
