A method for fabricating a substitute component for bone, including the processes of: provision of a chemical spray including at least three of calcium chloride, hydrogen phosphate, hydrogen carbonate and water to form a combined solution； reaction and precipitation of the combined solution onto a substrate； allowing the precipitated particles to form a porous structure on the substrate； applying substantially isostatic pressure to the porous structure to form a compressed structure； and (optional) providing one or more through-holes in the compressed structure to promote osteoinduction.
