The primary aim of the work described in this paper was to identify the tests that can be most sensitive to the changes in processing conditions and differences in interlayer bond strength which affect the quality of parts made by Fused Desposition Modelling (FDM). The quality of the bond between layers is very important to the structural integrity of FDM fabricated parts. The various mechanical properties of tensile, flexural properties, notched and un-notched impact strengths and the influence of changes in processing parameters and orientations of specimens on the quality was investigated. Analysis of variance (ANOVA) was used to compare the significance of the effect of processing parameters on the mechanical properties. On the basis of the data from experiments we conclude that a combination of measures of modulus, weight and impact strength can be used to infer the quality of a build on a FDM machine.
