Cobalt-Chromium-Molybdenum Alloy Kills COVID-19 in Minutes

The November 2021 International Journal of Molecular Sciences online article “3D Printed Cobalt-Chromium-Molybdenum Porous Superalloy with Superior Antiviral Activity” reviews research investigating the novel use of Laser Powder Bed Fusion (LPBF) to additive manufacture (AM) a porous Cobalt-Chromium-Molybdenum (Co-Cr-Mo) superalloy with potent antiviral activity (100% viral inactivation in 30 min). The Co-Cr-Mo material, commonly used in industrial AM medical and aerospace applications, exhibited superior antiviral properties, outperforming common antiviral metals such as silver and copper.

New Additively Manufactured Satellite

Fleet Space Technologies, Beverley, Australia, announced the planned development of a ‘constellation’ of metal AM satellites within the year. Aided by a recent $26.4 million Series B investment, the startup has expanded the scope of its dedicated R&D to create the Alpha satellite. The company believes this to be the world’s first entirely additively manufactured satellite, and it integrates Fleet’s advanced beamforming technology and patented antennas.

MIM is a Perfect Fit for Fitbit

The new Fitbit Luxe™, a fitness and wellness tracker from Fitbit, San Francisco, California, features a metal injection molding (MIM) stainless steel case. MIM was selected due to its precision and ability to provide “jewelry-like” appearance. The company believes the design is one of its most fashionable and comfortable devices yet.

2021 Excellence in Metallography Award


 

The 2021 Excellence in Metallography Award has been selected, and this year's winning paper is "Artificial Intelligence Applied to the Development and Characterization of PM Components" by Simon Gélinas*, Gabrielle Laramée and Carl Blais, Laval University. The paper was selected from among the highly qualified manuscripts that were presented at the PowderMet2021 conference in Orlando and critically evaluated for the prestigious award. The paper is available for download on the APMI website. It is also included in Advances in Powder Metallurgy & Particulate Materials—2021The authors will be officially recognized during PowderMet2022 in Portland, Oregon, June 12–15, 2022.
