The Alliance for the Development of Additive Processing Technologies (ADAPT), a research consortium based in the US focused on developing technologies to accelerate the certification and qualification of 3D printed metal parts, has invited Dr Wayne King to speak about additive manufacturing on 8 November 2016 at the Colorado School of Mines campus. 

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. The 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. 

‘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 ADAPT technical director Aaron Stebner. ‘This goal is the same vision for the data-informatics-based modeling that is at the heart of our work at ADAPT.’
