Come join ISE’s faculty and fellow students as they welcome Linkan Bian from Mississippi State University as he discusses a theoretical framework and partial solutions for the Laser-Based Additive Manufacturing (LBAM) process.
As always refreshments will be served from 10:30 – 10:50 am in room 428 Daniels Hall.
The Laser-Based Additive Manufacturing (LBAM) process has the potential to propel the United States to a worldwide leader in the production and repair of complex/precious parts which will impact automotive, biomedical, and other major industries. However, the highly dynamic thermo-physical transitions during the fabrication make it hard to identify operational conditions that result in targeted physical and mechanical properties (e.g., density, tensile, and fatigue). The associated uncertainty associated with AM processes leads to inadvertent and inevitable process anomalies(e.g., defects and porosity), causing fabricated part slack of satisfactory quality to meet the requirements of industrial applications. We propose a theoretical framework to characterize the parameter-process-property relationships of AM, using a combined experimental and analytical approach. By optimizing the process parameters and characterizing in-situ process signals, we demonstrate that our approach allows us to accurately predict the mechanical properties of fabricated parts and reversely optimize the processing parameters. Future work aims at transforming the AM procedure to a‘ hands-off’ operation governed by in-situ diagnostics and control which provides customized parts for targeted applications.
Linkan Bian is an Associate Professor in the Industrial and Systems Engineering Department at Mississippi State University. He received his Ph.D. in Industrial and Systems Engineering from Georgia Institute of Technology in 2013 and then joined MSU as an Assistant Professor. Dr.Bian’s research interests focus on the analytics of Big Data generated from complex engineering systems, especially advanced manufacturing systems. He has received over $7m funding from NSF, NIH, DoD, DoE, and industrial companies. Dr. Bian has published over 50 peer-reviewed papers that appear in prestigious journals. He received the Outstanding Young Investigator Award from the IISE, as well as multiple Best Paper Awards. He is an Associate Editor for IISE Transactions on the focus area of Design and Manufacturing.
