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. 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).
