Influence processing parameters of FDM 3D printer on the mechanical properties of ABS parts

Shafaat, Amir ; Rezaei Ashtiani, Hamidreza


3D printing has been a type of additive manufacturing (AM) that creates parts by adding or printing thin layers of material on top of each other using computer-aided design (CAD) models. Fused deposition modeling (FDM) is a 3D printing process that produces parts by heating, extruding, and depositing the thermoplastic polymers. FDM-fabricated products have been becoming increasingly popular in various industries such as medical, electronics, automobile, pharmaceutical, etc. This study has been carried out on a set of standard samples out of acrylonitrile butadiene styrene (ABS) which have been produced using the FDM process. A comprehensive mechanical property evaluation has been performed to determine the influence of the infill density and layer thickness of ABS (FDM-fabricated) on the ultimate tensile strength, elastic modulus, yield strength, fracture strain, and toughness (energy absorption) using a tensile test. From the result analysis, it has been found that infill density and layer thickness haveimportant effects on the tensile properties. The behavior investigation of ABS-filament freeform fabrication has shown that infill density of 100% and a layer height of 0.1 mm achieve optimized process parameters values.
