Abstract

The quality of fused deposition modeling (FDM) 3D printed parts are primarily influenced by the process conditions and mesostructural features. This study aims to establish the relationships between the process parameters/mesostructural features and the fracture resistance of printed parts. Double cantilever beam specimens of ABS were printed at different nozzle and bed temperatures, and with different layer height and layer width and then fracture-tested to measure the fracture resistance using J-integral in a finite element model. The result indicated that nozzle temperature and layer height had the most significant effects on the fracture resistance. The fracture resistance increased by ∼30% with 20°C increase in the nozzle temperature. The bed temperature and the layer width appeared to be less significant factors, compare to the nozzle temperature. The results of this work establish insight and guidance in the design of printed materials for structural and functional applications.
