The design of the graded porous cylinders. The top images show a schematic representation of the design, the bottom images are photographs of the corresponding printed samples. Unit cell dimensions: left = 3 × 3 × 3 mm, middle = 4 × 4 × 4 mm, right = 5 × 5 × 5 mm. The porosity gradient is obtained by adjusting the strut thickness in the specimens (from top to bottom: 0.20 mm, 0.31 mm, and 0.45 mm)
