A method of fabricating a bone substitute material, the method comprises the steps of: providing a foam material (4) having an open cell structure, substantially filling the cells of the foam material with a ceramic slip, removing the foam material, and sintering the ceramic slip to form a bone substitute material that is substantially a negative image of the foam material. The step of substantially filling the cells of the foam material with a ceramic slip includes the steps of immersing the foam material in the ceramic slip, drying the ceramic slip and again immersing the foam material in the ceramic slip. The bone substitute material produced has pores in the material corresponding to walls of the foam cells.
