Claim Text:
1. A method of additive manufacturing a superalloy component, the method comprising the steps of: i. providing a powder bed of superalloy powder on a substrate; ii. scanning the powder with a laser to create a melt pool and thereby selectively fuse the powder into a desired shape, thereby forming a first layer of the component; iii. replenishing the powder bed and scanning the powder with the laser so as to form a subsequent layer of the component onto the first layer; and iv. repeating step (iii) as required until a final desired three dimensional component is formed; wherein scanning the powder with a laser comprises selective scanning of a focused laser beam across the surface of the powder bed in a line-by-line manner; and wherein the spacing between adjacent scan lines is no more than twice the layer thickness being formed.
