Acoustic Nozzles Improve the Performance of 3D Printed Parts

Published on: 17-Sep-2018

​Recent research has discovered that acoustic signal processing could be used to monitor the build quality of a 3D printed part while in progress. There are 3D printable sound-shaping super-materials, and 3D printed objects have been implanted with sound data for tagging purposes. Nanyang Technological University, Singapore (NTU) researchers have found that acoustics can be used to manipulate microparticles inside the actual 3D printing ink itself to improve the final object's performance and functionality. For better performance, fibres in a polymer matrix that could help transfer loads from critical areas needs to be properly oriented and aligned. 3D scaffolds with a controlled hierarchical structure at the nano- and micro- levels could increase their mechanical strength, which is good for cell, tissue generation and load-bearing bone defect repair. In addition, using simple acoustic waves to focus microparticles inside the microchannel could delay accumulation on the wall, improving extrusion-based 3D printing.
