There is disclosed a method of manufacturing a component. The method comprises generating, by additive manufacture, an intermediate structure comprising a core corresponding to the component, and one or more excess portions to be removed and comprises machining the intermediate structure to remove the excess portions. The core is generated by a first additive manufacturing procedure and the one or more excess portions are generated by a second additive manufacturing procedure. The second additive manufacturing procedure differs from the first additive manufacture so that the excess portions are fused at a higher rate than the core.
