Looking to Increase the Strength of Your 3D-Printed PLA Parts? Give Them a Shake, Researchers Say
Vibration, normally an unwanted force that serves to ruin the finish of your 3D prints, could be harnessed to deliver stronger PLA prints on fused filament fabrication (FFF, also known as FDM) 3D printers — at least, according to researchers from the University of Ha’il, the Higher Institute for Technical Sciences Tarhuna, the University of Sfax, and the University of Sousse.
"Material Extrusion (MEX), particularly Fused Filament Fabrication (FFF), commercially known as Fused Deposition Modeling (FDM), has become one of the most widely used additive manufacturing technologies for producing polymer components," the team explains by way of background to the work. "However, the mechanical performance of printed parts remains limited by weak interlayer bonding and internal porosity. This study investigates the effectiveness of controlled low-frequency bed vibration in improving the physical and mechanical properties of PLA components manufactured by vibration-assisted FFF/FDM."
Think that eliminating vibration delivers better 3D prints? Not...
