One of the main limitations of parts made with Material Extrusion (ME) is their anisotropic mechanical behaviour. This behaviour limits the functionality of these components in multi-directional loading conditions. A critical factor for this mechanical behaviour is the poor bonding between layers. 5-axis ME has the capability to orientate the printed layers in order to limit the effect of poor inter-laminar bonding. Previous studies have investigated 5-axis ME, but not fully explored 5-axis capabilities of this manufacturing technique. To address this gap, this paper compares the mechanical behaviour of 3-axis and 5-axis ME samples when subjected to compressive loading. The results demonstrate how depositing material in “3D layers” can improve the consistency of a sample’s mechanical behaviour. This study indicates that 5-axis ME can enable more isotropic behaviour in printed samples.
