Claim:
1. A method of three-dimensionally shaping articles, the method being characterized in that it is performed using flexible cord(s) and comprises the following successive steps: winding at least one flexible cord around a support element, said cord incorporating a heating electrical resistance surrounded by at least a first set of yarns of thermoplastic polymer material, and said first set of yarns itself being surrounded by a protective sheath, and said protective sheath being made of yarns of linen, cotton, glass or carbon fibers; connecting the flexible cord to an electrical power supply for a given duration to cause the thermoplastic polymer of at least the first set of yarns surrounding the heating resistance to soften, the cord then taking on the shape imposed by the support element; cooling the cord; and obtaining the three dimensional object; optionally removing the support element in order to obtain the three-dimensional object independently of the support element.
