LAYER BUILDING PROCESS AND LAYER BUILDING APPARATUS FOR THE ADDITIVE MANUFACTURE OF AT LEAST ONE WALL OF A COMPONENT, AS WELL AS COMPUTER PROGRAM PRODUCT AND STORAGE MEDIUM

The invention relates to a layer building process for the additive manufacture of at least one wall region of a component including applying at least one powder layer of a material to at least one building-up and joining zone of at least one movable building platform, carrying out a first solidifying step, in which the material is irradiated selectively with at least one energy beam, wherein irradiation parameters of the at least one energy beam are set so a molten bath is produced and a defect-affected wall region of the wall is produced, without applying a further powder layer, carrying out a second solidifying step, in which the defect-affected wall region produced in the first solidifying step is irradiated selectively with the at least one energy beam, lowering the building platform layer by layer by a predefined layer thickness, and repeating the steps above one or more times
