Powder for manufacturing precious metal products, which have an appearance which is designed in advance and a precious metal content which is sufficiently high for being able to be hallmarked in accordance with existing laws and which are manufactured by means of free form fabrication (FFF) in the form of a CAD/CAM-controlled process during which the powder material is supplied in layers and is caused to bind metallurgically within the regions of each layer, and between these regions, where information stored in the CAD/CAM programming specifies that the product should consist of solid material, characterized in that the powder material should have a total precious metal content of at least 50% by weight and comprise at least one component which, during manufacture of the product, is melted down and which, in the melted phase, wets other components included in the powder, and has a powder size, powder form and other properties which are adjusted to the CAD/CAM-CONTROLLED FFF process in question.
