FDM printing technology produces parts with anisotropic properties. This means they are significantly stronger in the XY plane than in the Z-axis.
When designing functional components, it's crucial to consider the application and the direction of the loads. FDM parts subjected to tensile loads in the Z direction are far more prone to delamination and fracturing compared to loads in the XY direction, with tensile strength differences reaching up to 4–5 times.
Take into account upload orientation for achieving best strength for your part and position the part to align with the XY plane for areas under high stress.
How does part orientation affect the strength of 3D-printed parts?
