En raison du processus de superposition de la fabrication additive, les pièces ont des propriétés intrinsèquement anisotropes.
This means the mechanical properties are not uniform in X, Y and Z directions. Typically, and in particular with FDM printing, the Z direction is the weakest direction as this is the direction of the layering process. It’s important to consider the best technology and material if you require a part to be isotropic in X, Y and Z and consider the part strength to optimise part performance.
