An object of the present invention is to provide an optical fiber sensor embedding method for a three-dimensional (3D) metal printing structure capable of embedding an optical fiber sensor without any damage by regulating 3D printing dwell time at a location where an optical fiber sensor is embedded while embedding an optical fiber sensor for sensing temperature, stress, etc., in a high-temperature harsh environment close to a melting point of metal when manufacturing a 3D metal printing structure. Another object of the present invention provides an optical fiber sensor embedded 3D metal printing turbine blade manufactured by applying the embedding method so that the turbine blade, which is a complex and precise product, is manufactured using 3D metal printing but the optical fiber sensor is embedded using the above-described optical fiber sensor embedding method.
