| In this paper, research progress in the electroforming and 3D printing method for gold jewelry has been reviewed. The technical principle and preparative process involved in electroforming gold were briefly described. Electroforming gold is divided into two processes, cyanide and non-cyanide plating. For non-cyanide plating, a few different solution systems such as citrate and sulfite were introduced. 3D printing is a new method and can be applied to indirect molding in gold jewelry. Its application status and advantages in gold jewelry were analyzed, along with the technical barriers caused by the powder raw materials, equipment and other aspects in the 3D direct molding. Fianally, the development direction and market potential of electroforming and 3D printing technology in gold jewelry were prospected. |
