The 2021 Metal AM Outstanding Technical Paper Award

The 2021 Metal AM Outstanding Technical Paper Award has been selected, and this year's winning paper is "Electrostatic Charging and its Impact on Powder Flowability" by Louis-Philippe Lefebvre, Roger Pelletier and Cindy Charbonneau, National Research Council Canada. The paper was selected from among the highly qualified manuscripts that were presented at the AMPM2021 conference in Orlando and critically evaluated for the prestigious award.

The paper is available for download on the MPIF website. It is also included in Advances in Additive Manufacturing with Powder Metallurgy—2021. The authors will be officially recognized during AMPM2022 in Portland, Oregon, June 12–15, 2022.

LLNL explores laser beam shaping to improve metal AM printing


While additive manufacturing (AM) techniques have revolutionized metal parts design complexity, the traditional laser beams could lead to defects and poor mechanical performance.

Lawrence Livermore National Laboratory (LLNL) is exploring alternative shapes to the Gaussian beams commonly employed in high-power laser printing processes such as laser powder bed fusion (LBPF). In a paper published by Science Advances, researchers experimented with exotic optical beam shapes known as Bessel beams—reminiscent of bullseye patterns—which possess a number of unique properties such as self-healing and non-diffraction. They discovered that the application of these types of beams reduced the likelihood of pore formation and “keyholing,” a porosity-inducing phenomenon in LPBF exacerbated by the use of Gaussian beams.  

Electric Vehicles Outsell Diesel in Europe for First Time

According to data from 26 European markets, electric vehicles (EVs) and plug-in hybrids outsold diesel vehicles by 10,100 units in August, representing 21% of all cars sold in the month. Even with an increase in sales of EV’s and hybrids, new car registrations overall reported a decline of 18% to 713,714 units, marking the lowest recorded volume in August since 2014.

2021 Howard I. Sanderow Outstanding Technical Paper Award

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.

PowderMet2022/AMPM2022

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.
