America Makes has launched a new challenge with the Air Force Research Laboratory (AFRL) and GE Research. The Open Source-Additive Scanning Implementation Strategy (OASIS) Challenge seeks the submission of open-source computer codes and algorithms to help advance laser-based powder bed additive manufacturing (AM).

“While tremendous progress has been made in this space there are still challenges with the proprietary nature of commercial scan strategies,” said America Makes Executive Director John Wilczynski. “This challenge seeks to address those issues head-on and create a body of work that can be utilized across the industry.”

OASIS challengeEntrants will download data from a secure project website to be used to create a new innovative scan strategy code and algorithms. All strategy submissions will be evaluated with predefined code requirements and then the top selections will have samples printed in Titanium to be evaluated for material properties and scored.

As the goal of this challenge is to find real solutions to an important issue facing the AM community, results of the sample evaluation will be integrated into the America Makes National AM Roadmap and the America Makes Digital Storefront.

Together, the Air Force Research Laboratory (AFRL) and America Makes have made tremendous progress in advancing open framework software, controls, and equipment with multi-laser metal additive manufacturing (AM).  However, most commercial scan strategies are proprietary making it difficult to fully understand the process.

OASIS challenge Therefore, development is necessary in the open-sector to realize improvement in microstructural homogeneity, surface roughness, geometric tolerance, and distortion via optimization of scan strategies. The Open-source Additive Scanning Implementation Strategy (OASIS) Challenge is a direct challenge to the AM industry to advance temporal and spatial thermal management through the submission of innovative scan strategy codes, algorithms, and/or methods.

This Challenge leverages previous America Makes project (4039) where open-source software was developed, along with the current Acceleration of Large Scale AM (ALSAM) project (3024).

As a pseudonym, Victor has also had a fascinating made-up life story, living as a digital (and virtual) nomad to cover the global AM industry. He has always worked extra-hard whenever he was needed to create unique content. However, lately, as our editorial team has grown, he is mostly taking care of publishing press releases.
