America Makes and Air Force Research Laboratory Announce an Additive Manufacturing Modeling Challenge Series

Goal of the AFRL AM Challenge Series is to Predict the Internal Structure and Resultant Performance of Metallic Components Produced by AM

Youngstown, Ohio — November 25, 2019. America Makes and Air Force Research Laboratory, Materials & Manufacturing Directorate Structural Materials, Metals Branch (AFRL/RXCM), proudly announce an additive manufacturing (AM) Modeling Challenge Series, comprised of four individual Challenges, with $150K to be divided among awardees.

The AFRL AM Modeling Challenge Series represents another innovative approach America Makes, the National Additive Manufacturing Innovation Institute, and AFRL are taking to advance the AM industry. By challenging the brightest minds from industry and academia, the AFRL AM Modeling Challenge Series will be influential in the development of solutions focused on validating/improving the accuracy of model predictions for metal AM.

The goal of the AFRL AM Challenge Series is to make high-pedigree calibration data sets available to modelers to use in the calibration of the developed models as it directly relates to predicting the internal structure and resultant performance of AM metallic components.

“We are excited that the AFRL AM Modeling Challenge Series is now underway,” said America Makes Executive Director John Wilczynski. “The implications of the AFRL AM Modeling Challenge Series on the AM modeling and simulation area are substantial. We are optimistic that the Challenge Series will significantly improve the predictability and accuracy of models and simulations and the qualification of AM processes and materials.”

Scope

The AFRL AM Modeling Challenge Series seeks to account for material heterogeneity intelligently through geometry-sensitive property prediction at both the micro- and macro-structure level. Models and simulations that can accurately account for this type of variability can be utilized by the AM design process and may be critical when designing complex parts with thin features. The material, INCONEL® nickel-chromium alloy 625 (IN625), was used across all four Challenges as it is relevant to aerospace applications due to its corrosion resistance, elevated temperature performance, excellent fatigue, and thermal-fatigue properties.

Challenge participants will be asked to develop models and algorithms that produce dynamic material property prediction module(s), sensitive to geometry and local processing state.

As with all America Makes research and development projects, the AFRL AM Challenge Series directly relates to the America Makes Technology Roadmap, aligning to the AM Genome swimlane. The AM Genome swimlane was created to drive disruptive pervasive technologies that change paradigms, such as moving from serial processes to fully concurrent computationally enabled ones. This swimlane is the home for infrastructure technologies (access to open material property data, modular open simulation frameworks, multi-scale data management and sharing, etc.) and cross-cutting pervasive technologies (physics-based modeling and simulation methods, computer-aided materials development or ICME, more efficient material characterization and property prediction methods, etc.) that enable concurrent processes to be realized.

Eligibility

AFRL AM Challenge Series problems are open to academia, small and large businesses, and national laboratories, both in the U.S. and internationally. Data packages will be publicly released by AFRL and made available to participants.
