In-Situ Analysis of Vibration and Acoustic Data in Additive Manufacturing

Vibration from an erroneous disturbance harms the manufactured components and lowers a FDM printer's output quality. For moving machinery, vibration analysis and control are crucial. The additive manufacturing technique is the basis for 3D printing which utilizes mechanical movements of extruder to print objects and faults occur due to unwanted vibrations. Therefore, it is vital to examine the 3D printer's vibration pattern. In this work we will observe these parameters of FDM printer exemplified by MakerBot method X. To analyze, it is necessary to understand the motion it generates, and appropriate sensors must be selected to detect those motions. The sensor measurement values can be used to determine the printer's condition. We have used an accelerometer and an acoustic sensor to measure the vibration and acoustics produced by the printer. The individual output from these sensors are examined. The findings show that vibration occurs at relatively low levels during continuous motion because it only occurs at the components' soft edges. Due to the abrupt acceleration and deceleration during the zigzag motion, the vibration is at its peak.
