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

摘要

The invention relates to layer building process for the additive manufacture of at least one wall region (12) of a component (14). The layer building process comprises at least the steps a) applying at least one powder layer of a material (22) to at least one building-up and joining zone (I) of at least one movable building platform (24), b) carrying out a first solidifying step, in which the material (22) is selectively irradiated with at least one energy beam (28), wherein irradiation parameters of the at least one energy beam (28) are set in such a way that a molten bath is produced and a defect-affected wall region of the wall (12) is produced, c) 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 selectively irradiated with the at least one energy beam (28), d) lowering the building platform (24) layer by layer by a predefined layer thickness and e) repeating steps a) to d) one or more times. The invention also relates to a layer building apparatus (10), a computer program product, a computer-readable storage medium and a component (14) with at least one additively manufactured wall region (12).
