Method of additively manufacturing a structure on a pre-existing component out of the powder bed

Abstract

A method of additive manufacturing a structure on a pre-existing includes disposing the pre-existing component in a bed of powdery base material and levelling the component, such that a manufacturing plane of the component can be recoated with the base material and alternatingly recoating and irradiating the manufacturing plane with an energy beam in order to additively build up the structure, wherein the irradiation is carried out in that the manufacturing plane is scanned by the beam in a non-continuous way, wherein, for the irradiation according to a second vector for the structure, the beam is either only guided parallel with respect to a previous first vector, or the irradiation process is paused after the irradiation of the first vector for a time span between 1/10 second to 2 seconds until the irradiation is continued with the second vector.
