A process for producing {HEAD ~ an artificial bone model} in accordance with {TAIL ~ the selective laser sintering process} which comprises extending a powder material for sintering comprising 30 to 90 parts by weight of powder of a synthetic resin and 10 to 70% by weight of an inorganic filler to form a thin layer and irradiating a portion of the thin layer having the shape formed based on tomograpic information of a natural bone with laser light so that the irradiated portion of the thin layer is sintered
