On-Site Speaker (Planned) Kellis Kincaid
Abstract Scope Next-generation laser powder bed fusion systems will employ multiple beams to increase throughput and provide finer control of melt pool shape. This capability will be augmented by laser systems which are capable of dynamically changing each beam profile. However, the impact of scanning with multiple, uniquely shaped beams is not well understood. In this work, the open-source modeling tool AdditiveFOAM is leveraged to investigate laser-material interactions for dynamic multi-beam systems. A Gaussian spot and ring heat source model is calibrated to the seven published modes of the commercial nLight AFX-1000 laser. A comprehensive parameter sweep is carried out for each mode to determine the printability window and impact on build rate. With the parameter map established for single beam scans, the model is then be used to determine the optimal combination of scan paths for up to four concurrent beams. This work was supported by the DOE AMMT Office.
