Abstract: The present invention relates to a method for improving service life of mesoscopic gear manufactured by an additive manufacturing method. The outer diameter of the mesoscopic gear is characterized by range from 1 mm to 10 mm. The method according to the present invention provides introduction of compressive residual stress below the surface of the gear while the mesoscopic geometry remains the same. The second aspect of the present invention relates to the product manufactured by the method according to the present invention.
