Abstract: A production method for screw elements (1) with a screw body (3) with an axially through-opening (5) with internal gearing (7) for mounting on a support shaft and an outer contour (9) for closely meshing twin-shaft extruders. A metallic powder material (13) is arranged step by step in layers in the direction of a production axis (Z-Z) on a work platform (11), wherein a laser beam (19) for each layer of the screw element (1) irradiates the powder material (13) according to the data of a three-dimensional model in a specific irradiation sequence at specific sites of the layer. The powder material (13) is melted, fully in places, and bonded with the directly underlying layer, so that after hardening of the layers, a complete, stable screw body (3) is produced. Further, the invention relates to a screw element produced in this way.
