America Makes and the US Air Force Research Laboratory (AFRL), have announced the winners of its additive manufacturing (AM) Modeling Challenge competition.

Some US$235,000 will be divided among the awardees, the organization said.

The AFRL AM Modeling Challenge, which was launched in November 2019, includes four individual challenges aimed at improving the accuracy of model predictions for metal AM, using Inconel nickel-chromium alloy 625 (IN625).

The 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 at Northwestern University
  • Challenge 3: Macro-scale structure-to-properties predictions, QuesTek Innovations
  • Challenge 4: Micro-scale structure-to-properties predictions, University of Utah, Carnegie Mellon University, and Los Alamos National Laboratory.

‘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 of these four challenges 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.’
