Manufacturing of a metal component or a metal matrix composite component involving contactless induction of high-frequency vibrations

Method for manufacturing a metal component by additive manufacturing, the method comprising:

• providing a work surface on which the component is to be manufactured,
• providing at least one deposition material from which the component is to be composed,
• advancing the deposition material to a localized deposition area where it is added to the component being manufactured,
• providing heat to the deposition area so that a free-standing melt-pool at least comprising molten metal is provided, so that the deposition material is deposited for building up the component,
• arranging an electromagnetic primary coil movably above the molten metal,
• adjusting a vertical position of a primary coil to a predefined distance above and not in physical contact with an upper free surface of the molten metal,
• applying power to the primary coil so that an electromagnetic field is obtained,
• adjusting the vertical position of the primary coil to maintain the predefined distance, and
• maintaining the electromagnetic field for a predefined period of time so that a desired microstructure is obtained in the component being manufactured, and
• mutually moving the work surface and the deposition material in a way that results in the additive manufacturing of the component.
