America Makes and AFRL name awardees of AM Modeling Challenge Series

July 20, 2020

America Makes, Youngstown, Ohio, USA, and the USA’s Air Force Research Laboratory, Materials & Manufacturing Directorate Structural Materials, Metals Branch (AFRL/RXCM), have announced the awardees of its Additive Manufacturing Modeling Challenge Series. $235,000 will be divided among them.

The AFRL AM Modeling Challenge Series,  comprising four individual challenges, was launched in November 2019. The goal of the Challenge Series was to improve the accuracy of model predictions for metal AM parts using Inconel® nickel-chromium alloy 625 (IN625). 

Challenge participants were provided high-pedigree calibration and validation data sets needed to develop new models as directly related to predicting the internal structure and resultant performance of AM metallic components.

“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,” stated John Wilczynski, America Makes’ Executive Director. 

“The awardees of these four challenges certainly made solid contributions,” he continued. “They improved our understanding of the micro- and macro-structure level variability that was needed to advance the accuracy of modelling and simulation for AM metal. We thank all those who participated and extend our congratulations to the awardees.”

The AFRL AM Modeling Challenge Series project team awardees are:

  • Challenge 1
    Macro-scale Process-to-Structure Predictions, Dassault Systems Government Solutions Corp.
  • Challenge 2
    Micro-scale Process-to-Structure Predictions, The Wing Kam Liu Group, Northwestern University
  • Challenge 3
    Macro-scale Structure-to-Properties Predictions, QuesTek Innovations LLC
  • Challenge 4
    Micro-scale Structure-to-Properties Predictions, University of Utah, Carnegie Mellon University, and Los Alamos National Laboratory
