    • PROBLEM TO BE SOLVED: To provide a method for producing a precision three-dimensional shaped article especially suitable for a living body model in which a plurality of parts different in color tone, transparency, mechanical properties, physical properties, chemical properties, biochemical properties, etc., are formed compositely.
      SOLUTION: The three-dimensional shaped article is produced by a method for optical three-dimensional shaping by using at least two photo-curable resin compositions capable of reversible sol-gel phase transition by the change of temperature or a method for optical three-dimensional shaping by using at least two thermoplastic polymers or thermoplastic polymer compositions 60-200°C in flow starting temperature, or by combining the two methods.
