A method of manufacturing a base winding assembly of a stator. The base winding assembly includes a plurality of conductor loop groups each formed of a plurality of conductor loops that are open on one side, wherein the closed ends of the conductor loops that are open on one side can be arranged at one face of the base assembly and the open ends can be arranged at the opposite face side of the base assembly, wherein the manufacturing of the base winding assembly is done by an additive manufacturing process in which a layer-by-layer application and local solidification of build-up material takes place. Furthermore, a method for manufacturing a stator for an electric machine, as well as a base winding group of a stator and a stator are proposed.
