A support structure for supporting an object during the manufacture of same by means of an additive manufacturing method; method for generating such a structure. This support structure (10) for supporting an object (2) during the manufacture of same by means of an additive manufacturing method, the support structure and the object being manufactured simultaneously, consists of a plurality of horizontal and straight bridges (12), vertical pillars (14) and inclined connectors (16), a bottom end of a pillar resting on a bridge, on a base plane or on a point of a surface of the object, and a top end of a pillar carrying a connector, and a bottom end of a connector resting on the top end of a pillar and the top end of a connector corresponding to a point on the surface of the object or to a point to be supported of a bridge, each bridge being supported at least at each of the two end points of same, either by a connector or by a point of the object, and the pillars and connectors being capable of having a height of zero.
