The working group focuses on laser-based additive manufacturing of metals, polymers and thermoplastics. Additive manufacturing techniques for generating functional engineering, metallic products via Selective Laser Melting and Laser Engineered Net Shaping will be specifically pursued. Applications currently being observed include the biomedical, aerospace and defense industries. Some current research topics include: (1) accurate prediction of the mechanical properties of additively-manufactured metallic parts; (2) predictive modeling of their behavior during their build and while in service; and (3) control of the manufacturing process to produce functional parts with targeted properties and performance characteristics and (4) establishing AM standards for characterizing post-fabricated thermo-mechanical properties. The focus of this working group is to bring the MSU expertise together to address the current challenges in the additive manufacturing sectors at a national scale.

The working group is active in submitting competitive proposals to federal and state-level agencies and aims to work with industry partners. The AMWG group is also pursuing equipment-use time at Oak Ridge National Laboratories and the National Institute of Standards and Technology (NIST). To date, the AMWG has outputted 5 conference papers and presentations. Many journal articles are in preparation and all AMWG members are in constant motivation to publish in this lucrative research topic.

Significant effort is being made to create a multidisciplinary team of faculty, graduate and undergraduate students from multiple MSU departments/colleges to effectively investigate the diverse physical aspects of additive manufacturing which include: thermal behavior and modeling, solidification, material characterizations, mechanical behavior and modeling, control, process parameter optimization, and generating functionally graded materials. A “product-driven” consortium has been formed – namely, the Consortium for Laser Freeform Fabrication of Engineered Products with Enhanced Structural Integrity (CLF²) - that consists of nearly 20 committed members from industry, government, not-for-profit organizations and academia sectors - listed below.

The goal for CLF2 is to establish a unique broad-based consortium consisting of academic-industry-government partnerships, to engage in collaborative scientific research resulting in significant improvements in controlling and characterizing the material/fatigue properties of additively manufactured metallic parts. The Additive Manufacturing Working Group (AMWG) is to coordinate our efforts on advancing the state-of-the-art on additive manufacturing at MSU.

Research and academic faculty from any department at MSU is welcome to join the AMWG. The topic of additive manufacturing is broad and requires various skill sets and expertise. Therefore, faculty interested in performing cross-disciplinary research are encouraged to contact the AMWG officers for more information on how to actively participate.
