The invention refers to a method for selective laser melting additive manufacturing a three-dimensional metallic or ceramic article/component entirely or partly. The method includes successively building up said article/component layer by layer directly from a powder bed of a metallic or ceramic base material by means of remelting the layers with a high energy laser beam, moving repetitively across the areas, which are to be solidified. The movement of the laser beam is made of a superposition of a continuous linear movement and at least one superimposed oscillation with a determined frequency and amplitude. The oscillation is created by a beam deflection device and the same beam deflection device is also used for linear positioning movement.

The invention refers to a method for manufacturing a hybrid component including the following steps of manufacturing a preform as a first part of the hybrid component, then successively building up on that preform a second part of the component from a metallic powder material by means of an additive manufacturing process by scanning with an energy beam, thereby establishing a controlled grain orientation in primary and in secondary direction of at least a part of the second part of the component. The controlled secondary grain orientation is realized by applying a specific scanning pattern of the energy beam, which is aligned to the cross section profile of the component or to the local load conditions for the component.
