Abstract :

The 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 samplesâ�?�? mechanical properties and their printing quality were explored. It seems that the fill density affects samplesâ�?�? mechanical properties significantly and the variation of maximum load stress and the Youngâ�?�?s modulus changed linearly with increased density. Moreover, the fill pattern affects fiberâ�?�?s structure and determines the productsâ�?�? 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 â�?�?diamondâ�? 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 Youngâ�?�?s modulus compared to pure PLA and ABS.
