In-Situ Analysis of Vibration and Acoustic Data in Additive Manufacturing
Muhammad Fasih Waheed, Shonda Bernadin
Vibration from an erroneous disturbance harms the manufactured components and lowers the output quality of an FDM printer. For moving machinery, vibration analysis and control are…
Real time fault detection in 3D printers using Convolutional Neural Networks and acoustic signals
Muhammad Fasih Waheed, Shonda Bernadin
The reliability and quality of 3D printing processes are critically dependent on the timely detection of mechanical faults. Traditional monitoring methods often rely on visual insp…
