Influence of layer height and print speed on the mechanical properties of 3D-printed ABS

The use of 3D printing for manufacturing has assured to produce parts with complex shapes and designs. Fused deposition modeling (FDM) is one of the type of rapidly growing additive manufacturing technology. Poly (lactic acid) (PLA) or Acrylonitrile butadiene styrene (ABS) are the mostly used materials in Fused Deposition Modeling (FDM) machine. This paper is devoted to study the 3D printing parameters like influence of layer thickness and print speed on the mechanical properties of 3D-printed ABS. Nine Samples with three different layer height (0.1, 0.2 and 0.3 mm) and print speed (1000, 2000 and 3000 mm/min) were built using a FDM printer and their tensile strengths were tested using universal testing machine. The optimal mechanical properties of ABS material were found in sample of 0.2 mm layer thickness and at speed of 3000 mm/min.
