T

he Fused Deposition Modelling (FDM), which is one of the main additive manufacturing technologies, is widely used

in many fields with multiple materials. Additive manufacturing shows a rapid development over the last decade and

hence FDM printing machines have been improved remarkably. In this work, the effects of several set parameters on 3D

printed samples’ mechanical properties and their printing quality were explored. It seems that the fill density affects samples’

mechanical properties significantly and the variation of maximum load stress and the Young’s modulus changed linearly

with increased density. Moreover, the fill pattern affects fiber’s structure and determines the products’ structural properties.

The mechanical properties of samples and the printing time were also affected significantly with different layer thicknesses.

Samples with different fill patterns showed highly varying properties; e.g. samples with linear fill pattern showed the best

tensile properties where samples with “diamond” fill pattern can have a large deformation during tests. Furthermore, the effects

of different materials (e.g. PLA (Poly Lactic Acid), ABS (Acylonitrile Butadiene Styrene), carbon fibre reinforced PLA/ABS) on

the properties 3D printed structures were also observed and the results showed that the samples with both carbon reinforced

PLA and ABS are better in tensile properties than pure PLA and ABS. However, they were found to be more brittle in nature.

Moreover, the samples printed from carbon fibre reinforced materials showed a 45-55% increase in tensile properties and a

40-55% increase in Young’s modulus compared to pure PLA and ABS.
