There are several powder metallurgy-based manufacturing technologies that are in development or being practiced that have potential to significantly contribute to jewelry manufacturing. These include the traditional powder metallurgy technologies of press and sinter, metal injection molding (MIM), and hot pressing. The new non-fusion-based additive manufacturing technologies such as inkjet binding, inkjet printing, stereolithography, and extrusion methods will be discussed with their relevance to jewelry manufacturing. This paper will provide a review of powder metallurgy technologies and detail the current methods and applications of these technologies.
