Three-dimensional printing method, apparatus and printer

A three-dimensional printing method, comprising: acquiring printing path data of a three-dimensional printing model; and printing, according to the printing path data, the three-dimensional printing model, wherein adjacent printing paths are partially overlapped at adjacent positions. Also provided are a three-dimensional printing apparatus and a printer. By partially overlapping printing materials of adjacent printing paths, the probability of a clearance between the adjacent printing paths is reduced, a printing model can be better filled with the printing material, the compactness of the printing model is increased, and the quality of the printing model is improved.
