Abstract: The present invention relates to a novel method of producing in one and the same operation precious hallmarked precious metal products. The method is particularly suited for production of such precious metal products, i.e. jewelry and objets d'art, which have complex geometries. The basic principle of the invention is the use of the free form fabrication FFF, method known per se which involve a stepwise build-up in layers of the product from a precious-metal-containing metal powder.

Abstract: The present invention relates to metal powders mixtures which are intended for manufacturing precious metal products which have special designs and complex geometries, also including those which consist of several uninterrupted parts which are indivisibly but flexibly coupled to each other. From the powder mixture jewelry and other objets d'art are manufactured by making use of free form fabrication (FFF) technique. The invention also comprises jewelry and other ornamental products which are manufactured from the powder material in question using the FFF technique.
