HPC4Mfg | Modeling of Powder Dynamics in Metal Additive Manufacturing 2017
On August 10-11,2017, LLNL’s Global Security Principal Directorate and the High Performance Computing for Manufacturing (HPC4Mfg) Program hosted the Modeling of Powder Dynamics in Metal Additive Manufacturing meeting in Austin, Texas.
LLNL’s Wayne King served as the meeting chair and is the leader of LLNL’s Accelerated Certification of Additively Manufactured Metals Project. He and the organizing committee united 100 participants from industry, laboratory, and academia.
Presentations from keynote and plenary lecturers focused on the following topics: needs from models for powder spreading; flowability, spreadability, and segregation; effects of particle size, particle size distribution, and particle morphology; recycle and reuse of materials, and effects of environmental conditions. Breakout sessions were held to discuss each topic and gather feedback in areas such as scientific challenges and priority research directions.
There has been an increased interest in using modeling and simulation to understand the dynamics of powder spreading for metal additive manufacturing. A meeting report prepared by the organizing committee was submitted to DOE’s Advanced Manufacturing Office.
