3D printing parameters of acrylonitrile butadiene styrene polymer for friction and wear analysis using response surface methodology

Abstract

This study intends to analyse the coefficient of friction and wear properties of the acrylonitrile butadiene styrene polymer by determining the optimal parameters for 3D printing. The pin specimens were produced using the fused filament fabrication 3D printing. Response surface methodology is used for the multivariate analysis, and Box–Behnken Design is the chosen symmetrical design method. Changes to the dependent variables, coefficient of friction and wear rate, were analysed as a function of the nozzle temperature, layer height and printing pattern. The coefficient of friction and wear rate were measured using a pin-on-disc tribometer. A good agreement between the modelled and measured values of coefficient of friction and wear rate was observed. The study suggests that layer height affecting coefficient of friction and wear rate most significantly. It is determined that a layer height of 0.10 mm and a nozzle temperature of 234℃ using the triangle printing pattern is the optimal set of combination to minimise coefficient of friction and wear rate.

Correlation of tribo-mechanical properties of internal geometry structures of fused filament fabrication 3D-printed acrylonitrile butadiene styrene

“…Therefore, although surface roughness plays an important role in reducing COF over time, it does not have a significant effect on the tribo-mechanical properties of 3D-printed ABS with different internal geometries. The printing parameters were selected based on the optimum values of the previous study (Norani et al, 2020). Since the printing process parameters for all samples are similar in this study and thus surface roughness is assumed to be constant within a specific range and can be neglected.…”

“…SLS is a method that uses direct energy to melt thermoplastic material, whereas FFF uses thermoplastic filaments which are extruded from the tip of the nozzle to build parts layer by layer. However, owing to its ease of operation, low-cost machinery and reliability of the designed parts, FFF is considered the most suitable process for 3D printing (Rosochowski and Matuszak, 2000;Levy et al, 2003;Brenken et al, 2018). FFF has significant advantages in terms of eliminating expensive tools, flexibility and the ability to produce very complex parts and shapes.…”

A review of advances in tribology in 2020–2021

“…Various kinds of polymeric materials and a few kinds of alloys can be printed into 3D mechanical components. Hardness, friction, and wear properties of poly lactic acid (PLA) polymer printed using fused deposition modelling (FDM) method [586] and 3D printed acrylonitrile butadiene styrene polymer [587] were characterized respectively. Effects of 3D-printing parameters and surface roughness on tribological behaviors were revealed.…”

Grey relational analysis based optimization of process parameters for efficient performance of fused deposition modelling based 3D printer

“…Parameters such as layer thickness, air gap as well as build orientation, road width and the number of contours have been examined to determine how specimens printed using FDM wear over time. According to the findings of Norani et al,2020, when layer thickness and orientation rise, so does wear rate, while raster angle and air gap have inverse effect on wear rate while Fibres oriented at 90 0 had a higher coefficient of friction (Boparai et al,2015). Layer height had the greatest influence on wear behaviour, followed by nozzle temperature and pattern.…”
