This study investigates the effects of the raster angle, layer thickness, and interior fill style on the mechanical properties and strain evolution of 3D-printed Acrylonitrile Butadiene Styrene parts produced via FDM. Mechanical properties studied include yield strength, tensile strength, toughness, and resilience.
Tensile tests were performed in accordance with ASTM D638 standards at four different strain rates. Digital Image Correlation was used to investigate the influence of the aforementioned build parameters on macroscale deformation behavior of 3D-printed ABS.
Results indicate that the raster angle dictates failure by weak interlayer bonding or craze propagation. The “solid” interior fill style produced greater yield and UTS than “high density” counterparts, while the influence of layer thickness on investigated mechanical properties was inconclusive.
