Southern Illinois College Carbondale assistant professor Sangjin Jung has acquired a $200,000 Nationwide Science Basis Engineering Analysis Initiation grant to sort out reliability points in steel 3D printing. The 2-year venture focuses on designing steel elements that stay robust even when small manufacturing defects happen, addressing a key barrier to wider adoption of additive manufacturing in manufacturing environments.
Metallic 3D printing defects can come up from numerous sources together with laser energy settings, scan velocity, powder high quality, and tools put on. These microscopic flaws make half efficiency unpredictable and scale back producer confidence within the expertise. “Actual manufacturing isn’t good,” Jung stated. “As an alternative of pretending defects don’t occur, we construct them into the design course of and make the half strong anyway.”
Jung’s method differs from present strategies by modeling defect probability and affect through the preliminary design part moderately than discovering points throughout testing. His group will use simulations to optimize half geometry for defect tolerance from the beginning, probably decreasing expensive trial-and-error iterations. The worldwide additive manufacturing market is projected to achieve $100 billion by the early 2030s, however progress relies on proving constant efficiency at scale.
The analysis will leverage SIU’s steel 3D printing amenities and contain college students in interdisciplinary initiatives combining simulation, optimization, and hands-on printing expertise. The group plans workshops and utilized initiatives with native corporations, creating alternatives for capstone collaborations and internships. Outcomes may even be built-in into design for additive manufacturing curricula to modernize programs and laboratory work.
Jung brings business and educational expertise to the venture, having beforehand labored as a senior analysis engineer at LG Electronics and as a analysis scientist at Carnegie Mellon College and Pennsylvania State College earlier than becoming a member of SIU in 2021. The analysis goals to assist place the college and regional companies as a hub for additive manufacturing whereas coaching engineers to assist dependable steel 3D printing adoption.
