GOLDEN -- ADAPT, the Alliance for the Development of Additive Processing Technologies, a research consortium focused on developing technologies to accelerate the certification and qualification of 3D printed metal parts, will host Dr. Wayne King of Lawrence Livermore National Laboratory for a talk on Nov. 8.
King’s speech will be given from 4-5 p.m. in 250 Brown Hall on the Colorado School of Mines campus in Golden. Details can be found here.
“Understanding how materials and processes interact is critical to 3D printing’s role in driving innovation and advanced manufacturing,” said King. “The work underway at LLNL and ADAPT is key to expanding our understanding and plays a critical role in growing the 3D metal additive industry.”
“Dr. King heads a world-leading research group for physics-based simulations and high-speed measurement of additive manufacturing processes, with the goal of developing ‘feed-forward’ technologies to certify 3D printed parts as they are built,” said Aaron Stebner, ADAPT technical director.
“This goal is the same vision for the data-informatics-based modeling that is at the heart of our work at ADAPT.”
Dr. King will discuss “Simulation and Modeling of the Metal Powder Bed Fusion Additive Manufacturing Process.” Qualification of parts produced using laser powder bed fusion additive manufacturing is broadly recognized as a significant challenge. Physics-based models have been identified as being foundational to qualification of AM metal parts.
King’s presentation covers a multiscale modeling, including a model at the scale of the powder that simulates single track/single-multi layer builds and provides powder bed and melt pool thermal data. A second model computationally builds a complete part and predicts manufactured properties (residual stress, dimensional accuracy) in 3D. Modeling is underpinned by extensive experimental validation and is tied to experiment through data mining.
Dr. King currently serves as project leader of the Accelerated Certification of Additively Manufactured Metals Project at LLNL. This project focuses on developing physics-based models relating microstructure, properties, and process to performance of materials and includes predictive models for the laser powder bed fusion process. The project also focuses on using integrated in-process sensing, monitoring, and control technologies to accelerate part qualification.
ADAPT is a research and development organization dedicated to the creation of next-generation data informatics and advanced characterization technologies for additive manufacturing technologies. ADAPT uses these tools to help industry and government qualify, standardize, assess, and optimize advanced manufacturing processes and parts.
Founding industry members include Ball Aerospace & Technologies Corp., Faustson Tool, Lockheed Martin, Citrine Informatics.
