Where L is the experimentally measured perimeter of one square and A0 is the designed square area (taking into consideration the decrease in the area due to the experimentally measured printed fibre width). The mesh constructs were designed with dimensions of 1.2 cm × 1.2 cm width, 2 mm height, and 3 mm ´ 3 mm internal squares. At least three 3D printed replicates were measured per condition.
