Analysis of Applying Ultrasonic Frequency on a Desktop FDM Nozzle

Abstract

Fused deposition modeling (FDM) is an Additive Manufacturing (AM) that allows a designer or engineer discloses a desired shape by simply drawing a design on the computer. It is also the most economical AM process. Despite these advantages, it has the biggest drawback that it requires post processing to produce a good surface finish of parts produce. This research studies the application of ultrasonic to a desktop FDM system. The idea is to transmit high vibration from the ultrasonic transducer to the FDM system particularly on the nozzle. However, the idea has yet to be proven. This paper aims to examine whether the FDM nozzle is able to withstand the high vibration transmitted. The project was carried out using a CAD and ANSYS software. The CAD software is used to develop a 3-dimensional model and the ANSYS software is used to perform static and vibration analysis. 20 kHz to 30 kHz and 30 kHz to 40 kHz vibrations were applied. From the results of the analysis, the FDM can stand up to 40 kHz of frequency of vibration to the FDM nozzle. In addition, the lowest Factor of Safety obtained is 18.8975. Thus, it can be concluded that the nozzle of FDM can withstand the high vibration transmitted from the ultrasonic transducer.
