Experimental Study of Tensile Properties of ۳D-Printed Titanium-Reinforced ABS

This research examines the tensile properties of titanium powder-reinforced acrylonitrile butadiene styrene (ABS) composites fabricated via fused deposition modeling (FDM). Three weight-percentage (wt%) compositions of titanium-reinforced ABS were investigated: ۶, ۱۳, and ۲۰ wt%. Tensile specimens were ۳D-printed and compared with neat ABS. The tensile properties obtained after tensile testing are the elastic modulus (E), ultimate tensile stress (UTS) and elongation at failure. Experimental results revealed that the E and UTS improve about ۲۸ % and ۱۸ % respectively by adding ۶ wt% titanium. The elongation at failure decreased by ۱۲.۸۴%, indicating reduced ductility and increased brittleness. However, higher Ti contents led to reduced UTS, likely caused by particle agglomeration and stress concentrations.
