Description

Faculty of Manufacturing Engineering, Universiti Teknikal  Malaysia Melaka, Melaka, Malaysia. Fused Deposition Modeling (FDM) is one of the  Additive Manufacturing (AM) technology. Ultrasonic-assisted  FDM system has been proven to improve the mechanical  properties of the printed specimens. This study aims to explore the  uniformity of the amplitude of ultrasonic vibration that was used  during the printing process. The uniformity of vibration affected  the improvement of the mechanical properties of the 3D printed  part. If there is a bad uniformity of ultrasonic vibration, it will  influence and increase the variation of the tensile test result. An  open-source FDM printer attached with the piezoelectric  transducer in various locations of the printer platform was set up.  Five different positions and numbers of piezoelectric transducer  were set up in order to determine the best position and number of  the piezoelectric transducer for transmitting the vibration  uniformly to the printing platform. A laser scanning vibrometer  was used to determine the amplitude of ultrasonic vibration that  transmitted over the printing platform of an open-source FDM 3D  printer. From the results, it shows that with two piezoelectric  transducers at “Position 4” improved the uniformity of ultrasonic  vibration as it had the lowest standard deviation. The test also  revealed that the ultrasonic vibration effect uniformly on the 3D  printed specimens. In addition, it also reduces the variation and  provide better tensile test results of the printed specimens.
