A method for the manufacture of a three-dimensional article (10), comprising at least one layer of heat-formable material, which includes the steps of: heat forming a sheet of heat-formable material so as to obtain an intermediate product (12) having at least one fold line (16) and taking up less space than the finished three-dimensional article (10), the said heat forming being carried out in a mould of a shape substantially complementary to that of the intermediate product (12); the intermediate product (12) then being unfolded along the fold line (16) so as to obtain the finished three-dimensional article (10). <IMAGE> |
