Abstract

Fused Deposition Modelling (FDM) is one of the most important Additive Manufacturing (AM) technologies. This is a technology suitable for various engineering applications and currently used with many types of thermoplastic materials including Acrylonitrile Butadiene Styrene (ABS). AM-FDM printed ABS possesses an inherent capacity for property modifications as a function of printing parameters. The main goal of the present ongoing research project is to estimate the strength of the AM-FDM printed ABS for varying printing process parameters. In the present study, the mechanical and structural characterizations of AM-FDM ABS were evaluated by light microscopy and mechanical testing. Three-point bend flexural test results revealed the mechanical properties as well as the fracture behaviour according to the dimensions and printing strategies of the build-on specimens. An innovative transmitted-light microscopy experimental method was developed and utilized to investigate the crack propagation behaviour under bending.
