Researchers at Kennesaw State College have discovered that adjusting 3D printing construct settings could make printed parts almost 3 times stronger. The research, led by Assistant Chair Aaron Adams and mechatronics engineering scholar Eric Miller, focuses on how inside structural options have an effect on efficiency in vital purposes resembling nuclear power.
The analysis goals to deal with limitations in present nuclear gas utilization. “Proper now, the gas is within the type of a pellet concerning the measurement of a penny, and the pellets are stacked collectively like a roll of cash,” mentioned Adams, an affiliate professor of mechanical engineering know-how. “These gas pellets are then positioned inside a gas rod. When the nuclear response begins, they warmth up, increase, and are available into contact with the rod wall. As a result of they haven’t any room to increase, they have to be eliminated earlier than the gas is totally depleted, limiting how a lot of the gas can be utilized.”
The workforce is exploring how 3D printing can create inside channels and lattice buildings that permit supplies room to increase. Adams said the aim is to “obtain a 15 % improve in gas utilization utilizing advanced geometries.” Miller’s work entails designing fashions, getting ready simulations, and utilizing Finite Component Evaluation to check varied combos of lattice angles and densities.
The mission, supported by KSU’s Summer season Undergraduate Analysis Program and Sophomore Students Program, has introduced computational challenges. “If you happen to sum up our greatest problem in a single phrase, it’s sources, particularly our means to run extremely computational simulation fashions,” Adams mentioned. Miller will current the workforce’s findings at an upcoming American Society of Mechanical Engineers convention.
Miller famous the analysis has expanded his understanding past his typical coursework. “Moving into energy of supplies and FEA has been an excellent studying expertise,” he mentioned. “Even when one thing seems to be a failure, it’s nonetheless a hit as a result of it tells us what route to not take.”
