Researchers at Kennesaw State University in the United States have found that adjusting 3D printing settings can nearly triple the strength of printed parts, paving the way for safer, more efficient designs in high-stakes applications like nuclear energy. The project, supported by the Summer Undergraduate Research Program and the Sophomore Scholars Program, is led by Aaron Adams, assistant chair of the Department of Engineering Technology, and carried out by mechatronics engineering student Eric Miller at KSU’s START Lab. The team explores how subtle changes in lattice angles, densities, and internal channels influence material behavior. Adams notes that these improvements could help address inefficiencies in nuclear fuel systems, where tightly packed fuel pellets have little room to expand. “Right now, the fuel is in the form of a pellet about the size of a penny, and the pellets are stacked together like a roll of coins,” said Adams, an associate professor… read more
