Abstract
3D printing of Acrylonitrile Butadiene Styrene (ABS) and Poly Lactic Acid (PLA) were used to prepare specimens utilising fused deposition modelling (FDM) technology. Two colours of PLA filament were printed; white and grey, whereas ABS only in white colour. Determining the tribological properties of 3D printed samples have been carried out, through obtaining the frictional features of different 3D printable filaments. Alternating-motion system employed for measuring the tribological factors. Studying the difference between static and dynamic friction factors and the examination of wear values were included. A comparison among the tribological behaviour of the 3D printed polymers has been investigated. The printed white ABS and PLA specimens show insignificant differences in the results tendency. On the contrary, the grey PLA exhibits a considerable variation due to the incredible growth in the coefficient of friction and wear average as well.
Highlights
Three-dimensional (3D) printing technology is an additive manufacturing (AM) process that enables the fabrication of objects by adding layers of materials on top of each other successively [1, 2]
The wear rate and the friction force are the most critical values obtained for this study
In the light of these findings, it will be concluded with a statement on the effect of the 3D printing parameters on the tribological property
Summary
Three-dimensional (3D) printing technology is an additive manufacturing (AM) process that enables the fabrication of objects by adding layers of materials on top of each other successively [1, 2]. Thermoplastics such as acrylonitrile butadiene styrene (ABS) [5, 6], polycarbonate (PC) [7], and polylactic acid (PLA) [8], are commonly used due to their low melting temperature as well as their diversity and ease of adoption to different 3D printing processes.
