Dr. Joseph Tunick Strauss - HJE Company, Inc., USA
Dr. Strauss is president and engineer of HJE Company, Inc. He holds a Ph.D. in materials engineering from Rensselaer Polytechnic Institute. He has authored more than 50 published works. He organized and co-chaired the Additive Manufacturing Powder Metallurgy Conference (AMPM) in 2014/2015 and again in 2020. He is a member of the Technical Committee of the Metal Powders Industries Federation (MPIF); the Minerals, Metals & Materials Society (TMS) Committee on Powder Materials; the ASTM Committee B09 on Metal Powders and Metal Powder Products and the ASTM Committee F42 on Additive Manufacturing Technologies. Joe teaches additive manufacturing in the annual MPIF PM Short Course and co-presents a tutorial on additive manufacturing at the annual MPIF PowderMet Conference. He
was chosen to write the chapter on MIM of Precious Metals for the Handbook of Metal Injection Molding and the chapter on Additive Manufacturing of Precious Metals for the ASM Handbook on Additive Manufacturing. He received the Distinguished Service Award by the Metal Powder Industries Federation and was awarded a Fellow of the American Powder Metallurgy Institute. Joe has also received the Santa Fe Symposium® Ambassador Award and is a two-time recipient of the Collaborative Research and Applied Engineering Awards. This is his twelfth year presenting at the Symposium.
Current Developments in Powder Metallurgy-Based Manufacturing Technologies for Precious Metals
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.
