Abstract Additive manufacturing is used to produce open-cell scaffolds with tailored design to match bone performance. We used triply periodic minimal surfaces within a range of sizes and volume fractions designed to suit the needs of the different existing bone tissues – this meant manufacturing sub-millimetre unit cells with pore sizes between 200 and 500 μm. Ti–6Al–4 V is employed. Compression experiments reveal the stiffness and the collapse load of the scaffold as a function of geometry and density. This work confirms the suitability of the designed lattices to match the stiffness and the yield strength over a wide range of bone types.
