Method for manufacturing a three-dimensional item with metal pattern(s)

Abstract

The invention relates to a method for manufacturing a three-dimensional item comprising at least one metal pattern, comprising at least: a step A of providing a flat substrate of thermoformable material; a step B of forming on a surface of the flat substrate a temporary masking coating that adheres to said surface, to obtain a masked substrate having at least one unmasked area; a step C of thermoforming the flat substrate to give the latter a generally three-dimensional shape; a step D of metallizing the masked substrate to form a metal deposit on the latter, at least on said unmasked area; and a step E of eliminating said temporary masking coating, the thermoforming step C being carried out before metallization step D and before step E of eliminating said temporary masking coating, the metallization step D being carried out by non-electrolytic deposition from one or more metallization solution(s) containing at least one metal in metal cation form and at least one reducing agent adapted to transform the metal cation into metal, by spraying the metallization solution(s) in the form of one or more aerosol(s).
