CMU wins additive manufacturing award
In a partnership with the University of Utah and the Los Alamos National Laboratory, CMU was named one of the awardees in America Makes and the Air Force Research Laboratory’s additive manufacturing challenge titled “Mirco-scale Structure-to-Properties.” MSE’s Tony Rollett represents CMU on this project. The team collaborated to advance the accuracy of modeling and simulation for AM metals. In particular, the challenge aimed to improve the accuracy of model predictions for metal AM, using INCONEL® nickel-chromium alloy 625 (IN625).
“Going into the AFRL AM Modeling Challenge Series, we knew that the outcomes would potentially lead to significantly improved predictability and accuracy of models and simulations, and the qualification of AM process and materials,” said America Makes Executive Director John Wilczynski. “The awardees certainly made solid contributions. They improved our understanding of the micro- and macro-structure level variability that was needed to advance the accuracy of modeling and simulation for AM metal. We thank all those who participated and extend our congratulations to the awardees.”
Carnegie Mellon team wins top design
MechE’s Kenji Shimada and Erica Martelly’s face mask design, Moldable Masks, were named a top design in America Makes’ “Fit to Face Challenge.“ Fit to Face Challenge participants were tasked with optimizing a face mask’s continuous fit-to-face contact for a wide range of face types. “Judging the Fit to Face Challenge designs was difficult as the submissions were all very good,” said America Makes Technology Director Brandon Ribic, Ph.D. “It was clear that designers spent significant time developing these masks to meet each of the challenge criteria.”
Rollett and Cunningham co-author two of the most downloaded papers
Scientific Reports 2019, Journal of Synchrotron Radiation
MSE’s Anthony Rollett, as well as Ross Cunningham, who was a Ph.D. student in Rollett’s group and moved onto Messer after his graduation in 2018, are co-authors on two of the most downloaded papers in their field for 2018-2019. “Real time observation of binder jetting printing process using high-speed X-ray imaging” was in the top 100 in Materials Science in Scientific Reports 2019. “Ultrafast X‐ray imaging of laser–metal additive manufacturing processes” published in the Journal of Synchrotron Radiation was among the top 10% most downloaded papers between January 2018 and December 2019.
Wolf elected to America Makes Executive Committee
The Dean’s Office’s Sandra DeVincent Wolf was recently elected to the America Makes Executive Committee, the main advisory group of the institute that focuses on strategy, policy, and advocacy. Wolf is one of two representatives from academia, of eight total representatives on the committee elected from the membership community.

Opening of Mill 19 at Hazelwood Green covered in the media
NEXTpittsburgh, Pittsburgh Post-Gazette, CBS Pittsburgh (KDKA)
Mill 19, a new research and development hub, officially opened on September 4. Currently housing Carnegie Mellon’s Manufacturing Futures Initiative (MFI) and the Advanced Robotics for Manufacturing (ARM) Institute, the building is designed to be a place for open collaboration on manufacturing. The opening was covered by multiple local news sources, including NEXTpittsburgh, Pittsburgh Post-Gazette, and CBS Pittsburgh (KDKA). “We wanted to make this different—a special place where we can attract more students,” said ECE/BME professor and faculty director of MFI Gary Fedder to NEXTpittsburgh. Executive Director of MFI Sandra DeVincent Wolf also appeared in an interview on KDKA.
Beuth talks additive manufacturing best practices
MechE and the Next Manufacturing Center’s Jack Beuth spoke with ASME Essentials about best practices in additive manufacturing, such as how, “if you simply print out an existing design on an additive machine, it’s almost never cost-effective. You have to design that component to exploit the capabilities of additive manufacturing.”
