This paper studies the compressive properties of the 3D printed spherical-roof contoured-core (SRCC) sandwich panels under quasi-static loading. This shows that the presence of graphene even at a low percentage can alter the hardness value of the composite material. Also, the hardness increased with the increase in graphene ratio. The hardness of post-processed specimens has increased by 11.4% comparing to non-post treated samples. The horizontally printed specimens have offered the smoothest surface as compared to other build orientation samples. A worse mechanical attitude was gained when increasing the graphene concentration, owing to the porosity increase. The highest tensile strength attitude was observed in the lowest layer thickness (35 μm) specimens, due to the increase in the number of layers. The graphene percentage of 0.5 wt.% was suggested as the optimum ratio for attaining the best tribological behaviour results in this work, as it decreased the friction coefficient roughly 50%. Based on the SEM images, the freshly mixed sample showed a uniform distribution for graphene platelets with a smooth fracture surface, unlike the specimens printed after one day or a week.

The print orientation has the highest contribution parameter which affects mechanical features of the used materials compared to the other examined 3D printing process factors.įor DLP 3D printing, the non-cured specimens demonstrated the highest wear depth and lowest friction coefficient as compared to the cured ones. Meanwhile, the Upright sample showed a very fragile behaviour, with extremely rapid fracturing of the printed layers at the break point. The Young's modulus and UTS are maximum at On-edge print orientation due to its robust construction, while elongation at UTS and elongation at break are better at Flat orientation. The friction coefficient of 45° angle and Vertical orientation samples decreased at higher load due to the deformation in the contact area. Further, the wear depth and implicitly specific wear rate reduced with growing the applied load. The occurrence of the stick-slip phenomenon was more likely in the context of sliding under low loads. The black coloured specimens reported a high wear depth rate. Hardness and surface roughness of specimens were also tested and analysed for their association with tribological behaviour.įor FDM 3D-printed specimens, the results showed that the white colour samples have offered the highest friction coefficient, whereas the lowest was observed at the grey. SEM and optical microscope were used to study the microstructure and the surface morphology of printed components prior to and after the tribological tests. The tensile tests were investigated on 3D-printed specimens, and the tensile strength, UTS, elongation at UTS, and elongation at break have been assessed in consistence with the behaviour gained from the examined print settings. The effect of 3D printing parameters and additives' existence on the coefficient of friction, wear depth, and specific wear rate were evaluated. Two applied loads (150 N and 200 N) were employed throughout the experiments of tribological tests. The experiments of tribological tests were performed in alternative reciprocating sliding under dry conditions.

For DLP, the specimens were inspected with and without post-processing (heating and UV post-curing). Various print settings (build orientation, raster direction angle, and layer thickness) and material colours (white, grey, black, and red) were used during the specimens' manufacture.

Four different polymer materials were examined (neat PLA and bronze/PLA composite for FDM, and neat resin and graphene/resin composite for DLP). The tribological and mechanical behaviour of two 3D printing technologies (FDM and DLP) were studied comprehensively.
