Abstract
A method for producing a component is disclosed. In a first step, a planar component layer is produced on a base surface from a metal material which is above the melting temperature thereof. In a second step, shear stresses are introduced into the component layer produced in the first step by a friction pin which rotates about a rotation axis and which is pressed with a predetermined force onto an outer surface of the component layer opposite the base surface and which is moved along the entire outer surface of the component layer. Finally, in a third step, the first step is repeated on the outer surface as a base surface.

A method for producing a component, comprising:
- a) producing a planar component layer on a base surface from a metal material (M) above its melting temperature in a liquid state and is changed at that location into a solid state;
- b) introducing shear stresses into the component layer produced in step a) by means of a friction pin which rotates about a rotation axis (A) and which is pressed with a predetermined force (F) on an outer surface of the component layer opposite the base surface and which is moved along the entire outer surface of the component layer;
- wherein the axis of rotation of the friction pin extends transversely to the outer surface of the component layer and the friction pin is attached to the outer surface of the component layer with an end face extending transversely to the axis of rotation, wherein a recess is formed within the end face and symmetrically positioned relative to the axis of rotation, and a ring-shaped contact area of the end face bounds the recess and is configured to be pressed to the outer surface of the component layer;
- and
- c) repeating step a) on the outer surface as a base surface.
