The 2021 Howard I. Sanderow Outstanding Technical Paper Award has been selected, and this year's winning paper is "Mix Solution for High Green-Strength and Green Machining" by Amber Tims, Roland Warzel, Bo Hu, North American Höganäs and Per Knutsson, Asa Ahlin, Angelica Hansen, Höganäs AB. 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 leading American technical conferences on powder metallurgy (PM) and metal additive manufacturing (AM) will be held June 12-15, 2022, at the Oregon Convention Center, Portland, Oregon. 

It was another successful year for the PM Parts Compacting/Tooling Seminar. The seminar, held about every other year, dates to 1989 and continues to educate a variety of people throughout the industry, mainly catering to powder metallurgy parts and product fabricators.

The future may belong to electric cars, but for U.S. automakers, heavy PM-containing trucks will rule for years to come. Automakers in North America plan to build more big pickups and sport utility vehicles than electric vehicles well into the late 2020s, chasing sales trends that run counter to the Biden administration's goal of boosting EVs to half the market by 2030, according to internal production forecasts viewed by Reuters.

A boat equipped with a metal additive manufactured (AM) aluminum alloy rudder suspension helped Australia win a gold medal at the Tokyo Olympics. The parts exhibited good strength, high ductility, and corrosion resistance, and the parts were required to have the same mechanical properties as their cast counterparts. The aluminum alloy selected can be used for metal AM, sand casting, pressure casting and mold casting, with the mechanical properties of the material said to remain very similar in all processes.

British engineers who are perfecting a technique for transforming moondust into oxygen have made a breakthrough that could shape the future of space exploration. Using specially designed pilot reactors, engineers have successfully extracted air from simulated moonrock, leaving behind kilos of metal powder that could one day be used to build lunar habitats. This is the first time the by-product has been produced in these quantities.

A collaboration between Oak Ridge National Laboratory (ORNL), Tennessee Valley Authority (TVA), and France’s Framatome, has produced four metal AM 316 stainless steel fuel assembly brackets.  The components are currently in operation at TVA’s Browns Ferry Nuclear Plant in Alabama.

Two GE Aviation facilities producing advanced jet engine components recently passed major production milestones—one facility shipped the 100,000^th CMC turbine shroud, the other the 100,000^th metal AM fuel nozzle tip.

The Fraunhofer Institute for Laser Technology (ILT), Aachen, Germany, has received an award for decades of development in the field of Additive Manufacturing: The institute won a competition conducted by ASTM International and is now working on a project towards standardization of machine condition monitoring in laser beam powder bed fusion (LB-PBF). It is focusing on selecting and qualifying imaging sensor technology that can be used to specifically monitor the condition of LB-PBF systems. The institute will derive cost-reducing recommendations for end users from these data.

To support and promote quality technology transfer, we offer the following select manuscript, which was highly rated during judging of the AMPM2021 Metal Additive Manufacturing Outstanding Technical Paper Award review process by the MPIF Technical Board.

This APMI “Members Only” benefit is located on the APMI site and is open only to APMI members.
