Abstract
The method makes it possible to produce a decorated element for a timepiece or piece of jewelry. This decorated element may be, for example, a watch dial. The method includes the steps of taking a base substrate, and micromachining on said base substrate a mould or decorative partitions in a programmed pattern, and filling the mould or the decorative partitions with at least one filler material to obtain the decorated element. The filler material may be enamel.
Claims15
A method for producing a decorated element for a timepiece or piece of jewelry, the method including:
- forming at least one intermediate layer on a base substrate;
- arranging a powder in a programmed pattern on said base substrate and intermediate layer to micromachine on said base substrate a mould or decorative partitions;
- and
- filling the mould or decorative partitions with at least one filler material to obtain the decorated element,
- wherein the micromachining of the mould or the decorative partitions is obtained by the selective melting or selective sintering of the powder on the base substrate in a selective melting or selective sintering machine using a laser beam or an electron beam or in an additive fabrication machine of a metal, ceramic or ceramo-metallic material along a stored line of the pattern to be created,
- wherein the intermediate layer formed on the base substrate is an enamel layer, and
- wherein said decorated element includes the mould or decorative partitions filled with the at least one filler material.
A method for producing a decorated element for a timepiece or piece of jewelry, the method including:
- forming at least one intermediate layer on a base substrate;
- depositing a layer of positive or negative photosensitive resin on the base substrate and intermediate layer;
- placing a contour mask in a programmed pattern to be created on the photosensitive resin;
- illuminating the resin through the mask;
- removing the illuminated portions of the resin, where the photosensitive resin is of the positive type, or removing the non-illuminated portions of the resin, where the photosensitive resin is of the negative type;
- filling the removed portions of the resin with a metal to form decorative partitions or a mould of a metal on the base substrate;
- removing all the resin;
- and
- filling the mould or the decorative partitions with at least one filler material to obtain the decorated element,
- wherein said decorated element includes the mould or decorative partitions filled with the at least one filler material, and
- wherein the intermediate layer formed on the base substrate is an enamel layer.
