Highly porous and biocompatible titanium scaffolds were fabricated using metal injection moulding ofspherical titanium powder (powder size: -45 μm) with potassium chloride (powder size: -250 μm) as atemporary space holder. Property evaluation of scaffolds with different porosity fractions, confirmed ahigh level of compatibility between their mechanical properties and those of human cortical bone. Theoptimum sintering temperature was found to be 1250 °C producing scaffolds with more than 90%interconnected pores in the size range of 200-250 μm, Yield stress of 220 MPa and Young’s modulusof 7.80 GPa, all of which are suitable for bone tissue engineering. Increasing the sintering temperatureto 1300 °C increased the Young’s modulus to 22.0 GPa, while reducing the temperature to 1150 °Creduced the yield stress to 120 MPa due to incomplete sintering.
