America Makes Announces OASIS Challenge Winners

America Makes, with the Air Force Research Laboratory (AFRL) and GE Global Research (GEGR), has announced the awardees of the Open-source Additive Scanning Implementation Strategy (OASIS) Challenge recently at its annual Technical Review & Exchange event. The awards are worth $68K in total funding from AFRL.

Together, AFRL, GEGR, 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. 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.

“Continuing the advancement of open-source software and machine platforms for laser-based powder bed additive manufacturing is a priority for our industry and AFRL as the proprietary nature of commercial scan strategies inherently pose difficulties,” said America Makes Executive Director John Wilczynski. “The OASIS Challenge included learnings from three previous America Makes projects that were led by GEGR and built upon them to enable participants to devise innovative strategies, algorithms and methods to further advance this focus area. All the winners of the OASIS Challenge developed new and well-synthesized open-source computer codes for outputting laser scan paths that will be instrumental in creating a body of work to be leveraged industry-wide.”

The following project teams were selected as the OASIS Challenge winners:

– 1st Place, awarded $26.6K in funding: The Ohio State University (OSU)

– 2nd Place, awarded $16.6K in funding: OSU

– 3rd Place, awarded $11.6K in funding: Applied Optimization, Inc.

– 1st Honorable Mention, awarded $6.6K in funding: OSU

– 2nd Honorable Mention, awarded $6.6K in funding: OSU
