Disclosed is a method for controlling a laser beam for manufacturing three-dimensional objects by stacked layers, including, for each layer, a step for using a laser beam to solidify a zone corresponding to a two-dimensional object to be manufactured, such a two-dimensional section having a geometric contour. The method includes, for at least one the two-dimensional section, a step of acquiring (50) the geometric contour of the two-dimensional section, a step of determining (52) a reference path from the geometric contour of the section, the reference path having a shape correlated to the shape of the geometric contour, a step of determining (54) a set of paths based on the reference path, and a step of controlling (58) the laser beam to travel all of the determined paths using a travel strategy defining a travel order of the paths and a starting point for each path.
