METHOD FOR THE THREE-DIMENSIONAL SHAPING OF AN OBJECT FROM A FLEXIBLE CORD, A CORD FOR CARRYING OUT THE METHOD AND AN OBJECT PRODUCED IN THIS WAY

摘要

A method of three-dimensionally shaping articles, such as articles that are difficult to transport, includes the following successive steps:
placing at least one flexible cord (1) on a former (10), the cord (1) incorporating a heating electrical resistance surrounded by at least a first set of yarns of thermoplastic polymer material;connecting the flexible cord (1) 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 former (10);cooling the cord; andoptionally removing the former (10) in order to obtain the three-dimensional object.

1. A method of three-dimensionally shaping articles such as articles that are difficult to transport, the method being characterized in that it is performed using flexible cord(s) and comprises the following successive steps:
placing at least one flexible cord (1) on a support element such as a former (10), said cord (1) incorporating a heating electrical resistance surrounded by at least a first set (3) of yarns of thermoplastic polymer material; connecting the flexible cord (1) to an electrical power supply for a given duration to cause the thermoplastic polymer of at least the first set (3) of yarns surrounding the heating resistance to soften, the cord then taking on the shape imposed by the support element (10); cooling the cord; and optionally removing the support element (10) in order to obtain the three-dimensional object independently of the support element.
