Component produced by additive manufacturing

The present invention relates generally to components prepared by additive manufacturing (AM) methods, along with methods of preparing such components by AM. More especially, there is provided a process for the production of a component of an ignition device using an AM method by forming a layer of metal or alloy on a surface of a metal or alloy substrate; fusing the layer to the substrate; and repeating the addition of such layers upon one another to form a deposited metal or alloy attachment on the substrate.
